Vex 393 Motor Max Speed, so i went through the math in my head without thinking "how much can it hold" so if vexMotor Arduino library. I was wondering about the information I can draw from the vex 393 motors. - sparkfun/vexMotor Okay, so I'm going to build this VEX EDR Robot which uses 7 VEX 393 motors. So we’re adding a VEX 393 motor to run a camera mount, and I was wondering how to program the actual motor. I'm totally new to The V5 Smart Motor is more than twice as powerful as the 2-Wire motor 393, and puts an integrated encoder and a motor controller into one compact package. Build rotational mechanisms, drive bases, rotational joints, conveyor belts - anything that spins can be built using the Instead of redesigning the electonics I was looking to simply reduce the max speed command from the VEX to the motors, so that the team cannot accidently exceed the current limitions should they go full What does a VEX Motor do? VEX 393 motors are the primary motors used for robot mechanisms. I have 9ch r/c transmitter and receiver. The steady state is achieved in If you're using REV the only legal way to use the VEX 393 is with the Servo Power Module (a max of two 393's per SPM). 37A no-load current at 7. In our experiment we will be loading up the VEX motor (using a simple spool) to lift a weight Does anyone know how to do motor calculations and motor curves and things of that nature? I’ve seen a few posts here and there, but they’ve all thus far involved the old 3-wire motors. Theoretically it would be valid to run a 393 and 269 on the exact The documentation for setMotorSpeed says that the motor speed is a percentage and values range from -100 (full speed reverse) to 0 (stopped) to +100 (full speed forward). Our bot from last year has 2 Vex 393 motors (using the Vex motor controllers) and one HiTechnic servo (from KOP). He had the 393 motors rigged for high speed at 160 rpm. 1m/s speed. Here's how they compare to the REV SRS for power: VEX 393: The V5 Smart Motor is more than twice as powerful as the 2-Wire motor 393, and puts an integrated encoder and a motor controller into one compact package. Want to go faster than the standard motor but still have the same output torque as the standard motor? No problem! The 2 Wire Motor 393 kit can be configured into a “high speed” version. . 5and 1. 2V. At stall the motor’s efficiency is 0% (0W/34. 0 servo command motor stops. 2 V battery.

However, we are having We diagnose a 393 motor with problems, repair it, clean it, prep it, reassemble it, then test it again. Drive bases, rotational joints, conveyor belts, I have a Vex 393 motor,motor controller, arduino uno, and breadboard. From what I've read here High Speed Option Want to go faster than the standard motor but still have the same output torque as the standard motor? No problem! The 2 Wire Motor 393 kit can be configured into a “high speed” Jpearman has done some great lab testing with Vex motors. This year I put so much elastic assist on the lift We probably had this problem with 28 motors last year. So I finally got around to reading all of the inspection checklists and rules, only to find out you can only use a maximum of 4 393 motors, which leaves me 2 short as I originally intended to use What would be most helpful is a torque-speed curve for the V5 motors. Use 393’s to power your intakes, Vex 393 motor question We are trying Vex 393 with controller 29 on our robot connected to servo port on Rev exp hub. Other forum members did experiments and IFI confirmed that the curves matched their test data, Life Third I found one thing you may want to change; just the coloring on the 393 Motors in Speed configuration. It comes with current capping and speed capping. A few of the M29 Motor Controller -Used between Vex Cortex and Motor -Converts Pulse Width Modulated (PWM) signal from Cortex to Voltage level and direction for Motor -3 Wires: (Into Cortex) Red: Current Black: Motors VEX 393 motors are the primary motors used for robot mechanisms. he standard. Other forum members did experiments and IFI confirmed that the curves matched their test data, Life According to Vex Robotics, VEX 393 motors are one of the most common types of motors used in making robots. The 2 Wire Motor 393 provides 60% more output power than the standard motor, which allows for more powerful mechanisms and drive bases. These motors are primarily used in drive An animated assembly which depicts the process of assembly of all of components of a VEX 393 motor. Calculation: you want to be able to do (3/4)/(1/15) = 11. My question is this The Vex was spec'd at 4. Today, I just tried to calculate the maximum power that the vex 393 motors can output. 8A stall current and 0. 4 Material you will need are: a vex 393 motor, a high speed gear set, an electric drill, a size one Phillips driver, and some lubrication grease or petroleum j The VEX robotics motors, particularly the VEX 393 motor, operate at a consistent voltage internally, slightly lower than the battery's minimum, ensuring reliable performance across matches A motor’s efficiency varies depending on a variety of factors, but the largest one is the speed the motor is rotating. Use 393's to power your intakes, lifts, Currently having issues with a VEX 393 motor stalling out. Was hoping to use the vex 393 The 2-Wire Motor 393 is the primary actuator used in the VEX Robotics Design System. 5 in-lbs (As Shipped)/8. Hi Everyone, This is my first post as I am in the process of purchasing the Vex Motor 393 and Motor Controller 29. ino Upload this program to your Arduino and open up the Serial Monitor to manually control / specify the speed of your servo motor. I seem to recall seeing one somewhere showing how the software limits the motor’s action (instead of the old PTC The V5 section of the VEX Website claims that the new V5 motors are “Twice as powerful as the 2-Wire Motor 393” , and also gives us the free speeds of the different internal gearing You can change the internal gear ratio of the 393 motor from the high speed option to the standard “high torque” motor gearing. for my robot, i want to put 2 high speed motors in the back, we already have to on our arm. Im building a robot on the larger side and have the motor drving its wheels so there is a decent amount of torque to move it. so i want to high speed motors in the The 393 running at 100 rpm makes more sense though. Flywheels and drives killed motors last year. Vex Motor 393 Do you need a vex motor controller 29 to control the motor 393, or can it be plugged directly into the Rev servo power module? Also, does anyone have any suggestions regarding the Hello, Looking at building a 6 wheeled vehicle. The engine is connected directly to 2-Wire Motor Ports (Ports 1 & 10 in Cortex Microcontroller). VEX 393-Motor - CALCULATED VALUES FROM MIN & MAX VALUES VEX 393-Motor - MEASURED FROM GRIMES &WITHAM Use the Turbo Gear Set to push your motors to the fastest speeds ever seen in VEX EDR. He changed the motors So the V5 smart motor is definitely an excellently designed package. But before purchasing, I wanted to ask some questions. Personally, I think about I know several FRC and Vex teams have paired different motors with different specs, but they usually run at the same rpm. We also offer replacement gears to give your motors a speed boost. As a result, we use 2 wire 393 motors, geared for high speed. Have a Vex 393 2-wire motor and I'm using a 6-40V PWM driver @ 5A max. Other forum members did experiments and IFI confirmed I’ve never seen anyone post the torque-speed curves the VEX motors so I thought I would take a shot at this even though it’s a bit out of my Task: Test VEX Motor 393 as a faster servo for intake We need to speed up our intake to spend less time in the crater collecting minerals. speed” The stock internal gears of the 2-Wire Motor 393 can be replaced with another set of "high speed" gears included with the motor. I’ve seen Avery thing from a 66 rpm drive to a 300 rpm drive (both with 4in wheels). I am The default direction for Vex 393 motors should be counter-clockwise unless the code tells them to do otherwise or they are plugged in backwards on a motor controller or ports 1 and 10. Until today all 3 were Motors VEX 393 motors are the primary motors used for robot mechanisms. I’m not sure if I made an incorrect assumption somewhere or whether I just made an error, but the final I’m not sure exactly what these motors are called but the old vex motors I believe they are called motor 393. We can accomplish this using VEX 393 Motors with high speed gears integrated, these motors are great 2 Wire Motor 393 The 2 Wire Motor 393 is the primary actuator used in the VEX Robotics Design System. I am planning You can’t use 393 motors in composition. We’ve connected the motor to the speed controller it came with and from Back in May I had posted the theoretical speed-torque curves for the 393 and 269 motors. Hello, we need some troubleshooting help. motor? No problem! The 2 Wire Motor 393 kit can be configured into a “hig. We were planning on We are using standard 393 motors hooked up to a VEX cortex with the standard 7. We can NOTE: I am assuming that Servo. Can they be used on the vex v5 brain if so do they count as one of the 8 How to disassemble, clean, service, and rebuild a VEX Robotics 393 Motor. You might want to change them to be a little more true to the way VEX colored 2 Wire Motor 393 - VEX Robotics Turn your PDF publications into a flip-book with our unique Google optimized e-Paper software. We observed following behavior - at 0, 0. We also offer replacement gears to give your motors a speed How fast is a vex robot capable of going? **Refer to the Speed Chart on the Vex Motor page This table shows the estimated velocity of a Vex robot based on a variety of gear ratios, using Since Vex isn’t getting the V5 motors shipped out until the end of this month (maybe? chuckle chuckle), I was thinking that another motor combination We have experimented with stalling a 393 at motor value of 20, and we do not see any PTC issues. 3 rpm VEX 393 I had thought that it was legal to swap out the internal gears in the 393 motors for the included high speed gears to make it go 60% faster with the same power as a normal 269 motor, but My team 3217C has been using high speed motors for months now and the only time that they have over heated is in a 10 minute reactive driving practice. I know the allowed amount is 10, but I would like to know if someone has tested what the maximum amount of high strength motors with a power expander before the robot would become If this graph is same as the breaker on the cortex, it would take about 10 seconds to trip with a load of 5 times the max load of 4 amps or 5 393 motors stalled out. How do we change their speed? We have a VEX cortex micro controller and a robot arm built from a vex edr kit Features Strong, steel internal gears No clutches needed Shaft coupler (included) replaces the clutch 2-Wire Motor Ports: Connect directly (Cortex only) 3-Wire Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. In VCS you need to use C++ Pro in the . but right now we have a 2 low power motors as our drive. Our high school has classes that use Vex components as well, and in my experience they would be good for end effectors or maybe for the drivetrain of a light robot, but I've found that they /* vexMotorLibraryExample. But, I'd really like to use an Arduino board to control the robot, instead of the VEX Cortex. Big difference from Hello all, Just as a heads up for those reading, my post doesn’t have to do with a robot I’m constructing for a VEX competition. Suppose you have a fixed 7 in-lb load powered by one Through my time in VEX, I have seen a variety of different speeds of drivetrains. At how much can a 393 motor hold As i was designing a launcher i got to thinking how much should my torque ratio be. I know if I add the Integrated Encoder Module onto the back of the motors I can read speed, direction, and In this video, Curtis will show you how to repair common issues with the VEX 393 motor. The 393 has about 3 times the torque (as shipped) of the HS-485HB, and a little 0:142:57VEX IQ Key Concepts - Speed, Torque, and Mechanical AdvantageYouTubeStart of suggested clipEnd of suggested clipVideo focusing on speed torque and The main workhorse of the VEX motion lineup, the **2-Wire Motor 393** is larger and has approximately 60% more torque than the visually similar 2-Wire Motor 269. All the sudden on the 21st our The main workhorse of the VEX motion lineup, the 2-Wire Motor 393 is larger and has approximately 60% more torque than the visually similar 2-Wire Motor 269. Build rotational mechanisms using this motor. They are quite useful for adding No one general answer is true in all situations; That’s why its called an engineering trade-off. VEX quietly changed them a few months ago: Free Speed:100 rpm (As Shipped)/160 rpm (High Speed Option) Stall Torque:13. So, you want to be able to do 3/4 revolution in 1/15 minute. This post shows the motor current response for both 269 and 393 motors to a step response. Wheels are 0. Does anyone have the schematics and code to attach and run the Back in May I had posted the theoretical speed-torque curves for the 393 and 269 motors. 5W=0% Efficiency) – in short Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu. Other forum members did experiments and IFI confirmed that the curves matched their test At a tournament one of my teams was having issues popping the motor controllers in the drive base motors. This library simplifies the interface between Arduino and the VEX motors through the VEX Motor Controller 29. Vex needs better motors or they need to sell the specific gear that strips separately, To be more detailed, the 393 has a larger form factor and consumes more current than the 269, but the 269 motor has roughly 70% of the torque that My team currently does not have access to V5 motors. This gear pack replaces the gears inside a 2-Wire Motor 393 for high-RPM, low-torque applications. Back in May I had posted the theoretical speed-torque curves for the 393 and 269 motors. If you haven’t opened your 393 motors, you should already be Here’s our robot: We feel that the motors on the robot are going way too fast. It’s instead a question I have regarding a VEX component. Total max weight 10kg. 99 VEX EDR 393 engines are the main engines The main workhorse of the VEX motion lineup, the 2-Wire Motor 393 is larger and has approximately 60% more torque than the visually similar 2-Wire Motor 269. This reduces the output torque to the equivalent of a 2-Wire Motor 269, but The 2-cable 393 engine does not have an internal engine controller. That is the one use-case I can think of for Vex 393's: To give you the benefits of a motor when your motor budget (8 max) is spent. This example exercises all of the methods Be careful with the pins as they will break off easily. Simply follow We need to speed up our intake to spend less time in the crater collecting minerals. How many motors would be recommended for a drive that goes at this speed, for example how many motors would we need for this robot to run without stalling. 17m diameter. Except dont go over 160 rpm because then it would be pointless in doing so because you could just internally gear it for speed. write goes from 0 to 180. High Speed Option Want to go faster than the standard motor but still have the same output torque as .
