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

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

New 3-Wire-Reversible AC Fixed Speed Gearmotors

New 3-Wire-Reversible AC Fixed Speed Gearmotors

We expanded our popular FX line of parallel shaft gearmotors by adding (9) new AC models. The all-new 42R6-FX combines our new 3-wire reversible 42R frame AC induction motor with our completely redesigned and updated FX gearhead. The new gearmotor provides up to 40% more torque than previous E/F models. New synthetic lubricant allows the FX gearhead to operate at

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

Design Tips for Gearmotor Applications

To select the best gearmotor for an application, one must go into more detail than just selecting the best suitable output speed and torque. Here are five criteria you should consider. 1. Gearmotor Mounting Orientation Gearmotors are typically designed to be mounted with the gearbox level with the motor, and with the drive shaft in
