This small and affordable DC gearmotor comes with its own 2" diameter wheel. The wheel has a 1/2" wide rubber tire for terrific traction. Includes 1" standoffs and hardware, so that you can attach the motor to your own robotic base. The motor is double-shafted. On one end is the wheel; on the other is a 1/8" locking collar. There is ample room to mount a small optical wheel encoder next to the locking collar if desired. Specifications (includes wheel): Width: 2 5/8", Length: 2 1/8", Height: 2", Wheel diameter: 2", Wheel width: 1/2", Weight: 1.5 oz., Motor voltage: 3-4.0v (nominal), Current: 250 mA (no load @ 4vdc), and Speed: Approximately 120 rpm (no load @ 4vdc.) The motor can be driven using an IC or discrete transistor H-bridge. We recommend a bridge with no less than 1A per channel, at 4.5 vdc or less. 1 Each |
