Derry’Worm Gear Motors are designed to generate high torque in a small package size. Worm Gear Motors are great for applications that require a self- locking or breaking feature since the output shaft can’t rotate when there’s no power applied. Additionally, Worm Gearheads can transfer motion in 90 degrees. With various reduction ratios, precision cut gears, voltages and sizes, Derry has a DC Worm Gear Motor solution for your application.
