Introduction to AC Gearmotors and Motors

This blog post is from an updated section of Bodine Electric’s Small Motors Handbook. To download this article as a PDF, please click here. Although commutator and brush assemblies may be used in some types of alternating current (AC) gearmotors and motors (series-/universal wound), brushless induction-type designs are by far the most common and most reliable for industrial AC

Low-Voltage, Right-Angle Brushless DC Gearmotor Combines Four Drive Components in One Compact Package

Low-Voltage, Right-Angle Brushless DC Gearmotor Combines Four Drive Components in One Compact Package

The new type 34B4/FV-5N gearmotors combine Bodine’s 34B brushless DC motor with a compact and cost competitive right-angle gearhead, a built-in PWM speed control, and an optical encoder. Together, they create a high-performance drive package that radically simplifies design, wiring, and assembly. The 24 VDC 34B/FV-5N gearmotors are ideal for a wide range of low-voltage

Introduction to Brushless DC (EC) Motor and Gearmotor Technology

Brushless DC Gearmotors and Motors In Section 3.1 of the Bodine Electric Handbook we discuss how motor action is achieved in a conventional permanent magnet DC (PMDC) motor. A segmented commutator rotating within a stationary magnetic field causes mechanical switching of the armature current. In a brushless DC (BLDC) gearmotor or motor, the magnetic field

Advantages and Disadvantages of Planetary Gearmotors

Advantages and Disadvantages of Planetary Gearmotors

We design all our standard parallel shaft (helical or helical/spur) and right angle (worm or helical/worm) gearboxes in-house, and all gearheads are manufactured and assembled in our main factory in Iowa. Occasionally, we’ll receive a request to mate one of our standard AC, DC or BLDC motors to a planetary gearhead. To identify the best gearmotor option for our customer’s
