What Are Gear Motors?

Gear motors, or gearmotors, are electric motors connected to some type of enclosed gear reduction box. They are sold and used as a single integral unit, and they offer the ability to reduce speed while increasing torque. Gear motors come in a wide array of shapes, sizes and types of gearing. The most common types are right-angle gear motors and inline gear motors.

The Basics of Gear Motors

Gearmotors are basic in design, using some combination of plastic and/or metal. One of their greatest benefits is that they eliminate the need of having a separate gearbox and electric motor.

The motor powers the gearbox, turning the box and creating energy. As a packaged set, they work together to increase torque (force) while keeping RPMs (speed) low.

What Are the Different Gear Motor Types?

The two most common gearmotor types are right-angle gear motors and inline gear motors:

Of these five gear sets or gearings, the most common are worm, spur and planetary.

Gear motors can be purchased with a variety of AC (alternating current) or DC (direct current) motor types. They also come in many reduction ratios to accommodate a vast number of applications such as automatic door operators, food & beverage equipment, and robotics.
