  Hi-Speed DC Gearmotor and Wheel

Super affordable high-speed DC gearmotor and wheel combination. At 4.5 vdc (a common voltage when using an H-bridge at 6 volts) the wheel turns at approximately 300 rpm no load. Speed decreases with load. Current draw is about 1.5 amps with nominal load, and motor speed is approximately 125-150 rpm. This motor is ideal for fast and nimble robots, and speed may be controlled via PWM using a suitable H-bridge controller.


  • Dimensions: 5.5" x 2.5" x 2.5"
  • Weight: 3.4 oz (98 grams)
  • Wheel dimensions: 2.25" diameter, 1.125" wide
  • Wheel material: Rubber

The motor is double-shafted, with a 3/4" shaft protruding on the opposite end of the wheel. Use this shaft to mount a wheel encoder.

The motor may be attached to your robot in a number of ways. For your convenience, we offer a mounting bracket set for attaching the motor to the underside of a robot base.

Optional mount includes two metal brackets,
two 1.75" standoffs, and assorted hardware.
