Worm Gearbox Gearmotor

Worm and Wheel Gearmotors. Permanent Magnet DC motors together with Worm Gear type Gearboxes offer a relatively high torque output in a compact size and with an output at right angles to the motor. An advantage of Worm and Wheel Gearboxes is limited back drivability: the worm driven by the motor can easily turn the gear on the output, but the gear cannot turn the worm. This provides a form of brake which can be useful in certain applications for example lifting. These motors can be run in both directions.
