EDR 393 Motors & Servos
VEX 393 motors are the primary motors used for robot mechanisms. We also offer replacement gears to give your motors a speed boost. Use 393's to power your intakes, lifts, and drivetrains.
The 2-Wire Motor 393 is the primary actuator used in the VEX EDR. Build rotational mechanisms, drive bases, rotational joints, conveyor belts - anything that spins can be built using the 2-wire Motor 393.
The 2 Wire Motor 393 provides 60% more output power than the standard motor, which allows for more powerful mechanisms and drive bases.
- Strong, steel internal gears.
- Can be configured into a "high speed" version.
The 2-Wire Motor 393 does not have an internal motor controller.
The motor connects directly to 2-Wire Motor Ports (Ports 1 & 10 on the Cortex Microcontroller). For 3-Wire Motor Ports (Ports 2-9 on the Cortex), a Motor Controller 29 must be used in between the Microcontroller and the motor.
| Output Stage Driving Gear | Output Stage Driven Gear | Output Speed (RPM) | Output Stall Torque (N*m) | IME Ticks per Revolution | |
| Standard Motor 393 Gearing | 10t | 32t | 100 | 1.67 | 627.2 |
| High Speed Option (included with Motor 393) | 14t | 28t | 160 | 1.04 | 392 |
| Turbo Gear Set (sold separately) | 18t | 24t | 240 | 0.7 | 261.333 |
Lose your gears? This convenient replacement gear pack for the 2 Wire Motor 393 will get you going again without having to purchase a new motor. Includes one full set of gears.
- Only for the 2 Wire Motor 393
- (1) High Speed Gear Set
- (1) High Torque Gear Set
- (1) Set of replacement case assembly screws
Use the Turbo Gear Set to push your motors to the fastest speeds ever seen in VEX EDR. This gear pack replaces the gears inside a 2-Wire Motor 393 for high-RPM, low-torque applications.
- Only for 2-Wire Motor 393
- 240 RPM output speed is 140% faster than standard gearing
- Use with external gearing or large wheels for even more speed
Servo motors are a type of motor that can be directed to turn to face a specific direction, rather than just spin forward or backward.
- Expand functionality
- Add pan and tilt to a camera
- 100 degrees of rotation
- Do exact positioning
For use with a VEX EDR Continuous Rotation Motor or VEX EDR Servo.
