Updated Handbook Section: PMDC Gearmotors and Motors

This section of the Bodine Handbook refers to permanent magnet DC (PMDC) gearmotors and motors. We review their main features and benefits such as: linear speed-torque performance characteristics, high starting torque, quiet and easy to wire and control. PMDC gearmotors and motors offer starting torque of up to 175% and deliver rated (continuous) torque over the full speed range. Bodine literature no. 07481082.B.

Updated Handbook Section: AC Induction Gearmotors and Motors (incl Inverter Duty)

Chapter 2 in Bodine’s Gearmotor Handbook describes operation and function of AC induction motors and gearmotors. We discuss the various winding types (split-phase, single-phase, shaded-pole, and 3-phase) as well as how the line frequency, supply voltage and pole count affect motor performance. This updated PDF includes new information on the characteristics, features and benefits of variable-speed, AC inverter-duty gearmotors and motors! Bodine literature no. 07481092.B.

Updated Handbook Section: BLDC Gearmotors and Motors

In section 3.3 of our Gearmotor Handbook we discuss the features and benefits of brushless DC (BLDC) gearmotors. These motors are also referred to as electronically commutated (EC) motors. BLDC gearmotors and motors are ideal for continuous duty applications, can reverse at rest, or during rotation (motors only; gearmotors must always come to a full stop). One of the key benefits of BLDC motors is that they provide the same performance as PMDC motors, but without the need for brush maintenance or brush replacement... Bodine literature no. 07481090.B.
