Line Start Internal Permanent Magnet
101FR stator rotor SZ

Line-Start permanent magnet synchronous motors have the characteristics of high efficiency, synchronous speed, without having the need for a variable frequency drive (VFD).  It can directly replace the current applications of induction motors to achieve efficient operation. Regal has models in research and development covering scroll, screw, and reciprocating compressors in power ranges from 0.5kw to 150kw.
