What is a Synchronous AC Motor? Hysteresis- and Reluctance-Type Designs

What is a Synchronous AC Motor? Hysteresis- and Reluctance-Type Designs

The difference between the speed of the rotating magnetic field of an induction motor (which is always synchronous) and the speed of the rotor is known as “slip.” When the rotor design enables it to “lock into step” with the field, the slip is reduced to zero and the motor is said to run...

AC Induction Motors with Squirrel Cage Rotors

AC Induction Motors with Squirrel Cage Rotors

Why is it called a “squirrel cage rotor?”: Most fractional horsepower (FHP) AC induction motors utilize a die cast rotor design that consists of a skewed lamination stack with die cast rotor bars and end rings. The common term for this rotor design is “squirrel cage”, because if you remove the steel laminations after the

Choosing the Right Gearmotor for Your Application

Choosing the Right Gearmotor for Your Application

What is a gearmotor? A gearmotor consists of a small motor designed specifically with an integrated gear reducer (gearhead). The end shield on the drive end of the motor provides 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

Brushless DC Gearmotor Overview – Features and Benefits

Brushless DC (EC) Gearmotors and Motors – What Is a Brushless DC Motor? Brushless DC motors could be called “inside-out permanent magnet motors” because brushless DC motors have their magnets on the rotating part of the motor instead of on the stationary part. Accordingly, they have their windings on the stationary part of the motor

Quiet Gearmotors for Medical Equipment

Quiet Gearmotors for Medical Equipment

Gearmotors in mammography equipment are used to raise and lower the scanner to accommodate the patient’s height. The primary design objective is smooth and quiet operation. Our team of design engineers addressed four aspects of the gearmotor design that contribute to quiet operation. Worm Gearing Bodine recommended a right-angle gearmotor with worm gearing. The sliding

Model 2999 New Rugged AC Motor Speed Control

Bodine expands its extensive line of AC, PMDC, and BLDC speed controls with the new Model 2999. Featuring an industrial-grade NEMA-4X/IP-65 watertight aluminum die-cast enclosure, the model 2999 drives 230 VAC, 50 or 60 Hz, inverter-duty, 3-phase gearmotors rated up to 1 HP (746 W). It operates from single-phase 115 or 230 VAC, and it

Sizing a Fuse for a Bodine Gearmotor, Motor or Speed Control

Benefits of Fuse Protection 1. A fuse between the motor and AC line (to be used with single phase AC motors/gearmotors) provides motor protection under stall conditions and protects personnel from ground faults in the motor. It may not protect the motor from overheating under overload conditions. 2. A fuse between the motor and its
