A gearmotor is basically a combination of a gear reducer and an ac or dc electric motor, with the gears and the motors combined into one unit. Most industrial gearmotors use ac motors, typically fixed-speed motors. However, dc motors can also be used as gearmotors, particularly in automotive applications.
Likewise, the gear reducers themselves can be different types such as helical, bevel gears or planetary types. And the physical configuration of gearmotors can differ as well including inline types, right angle, and shafted or hollow-shaft configurations.
In this installment of Motion Control Classroom, you’ll find resources covering the basics of gearmotors and gearmotor accessories, but also how to select the right gearmotor to meet your particular application’s requirements. You’ll also find information on gears and gearboxes, including gearbox service factor and service class.
