Recording duration: 55 minutes

This presentation focuses on AC motor redesigns involving speed changes. Service centers encounter scenarios such as the procurement of a single-speed motor that must be redesigned for two speeds or redesign of an existing two-speed motor for use on an adjustable-speed drive.

Topics covered include:

• Single-speed, one-winding to two-speed, one-winding
• Single-speed, one-winding to two-speed, two-winding
• Two-speed, two-winding to single-speed, one-winding
• Two-speed, one-winding to single-speed, one-winding

The redesign examples are performed using EASA’s AC Motor Verification & Redesign program, including use of the integrated motor winding database for locating comparative data. Examples will include other changes such as voltage, frequency and horsepower.
