While this article focuses primarily on the electrical aspects of selecting a 3-phase squirrel cage induction motor (SCIM) replacement for a DC motor or an AC 3-phase ... For example, consider a 30-hp ...

Full-voltage, single-speed motor starters: Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters ...

Though uncommon, squirrel-cage rotors can fail. Here are tips on how to find the problem, fix the rotor, and get the motor running again.

The two VFD-driven vertical motors feature respective frame sizes of 450 and 500 and deliver outputs of 850 kW and 1000 kW at a nominal voltage of 690 V. The ship motors boast IP55 ingress protection.

I use three phase induction motors in some of my equipment. To control them, because they work either over single phase 120, or single phase 240, depending on the motor, I use what are called VFDs.
