Drive on.

The 2-Wire Motor 393 is the primary actuator used in the VEX Robotics Design System. Build rotational mechanisms, drive bases, rotational joints, conveyor belts - anything that spins can be built using the 2-wire Motor 393.

  • 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.
