In our company history<\/a>, we mention that Bodine Electric is one of the pioneers in the design and development of small (fractional HP = FHP, less than 1 HP) gearmotors in North America. Bodine Electric introduced the first integral gearmotors in the 1920s. Here is a brief discussion on how we define a gearmotor<\/strong> or geared motor<\/strong>\u2026<\/p>\n

What is a Gearmotor?<\/strong><\/p>\n

A gearmotor (or geared motor) is a small electric motor (AC induction, permanent magnet DC, or brushless DC) designed with an integral (non-separable) gear reducer (gearhead) attached. The end shield on the drive end of the motor (light blue, below) is designed to provide a dual function. The side facing the motor provides the armature\/rotor bearing support and a sealing provision through which the integral rotor or armature shaft pinion passes. The other side of the motor end shield provides multiple bearing supports for the gearing itself, and a sealing and fastening provision for the gearhousing (orange, below). This construction offers many benefits for a user and eliminates the guesswork of sizing a motor and gear reducer on your own.<\/p>\n

In general, gearmotors<\/a> function as torque multipliers and speed reducers, requiring less motor power to drive a given load. The gear housing design, the gearing type, gear lubrication, and the specific mode of integration all affect the gearmotor performance.<\/p>\n
