AC Motor Redesign: Speed Changes
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.
