NPM Shading-Pole Type Synchronous Motor (Unidirectional)

The NPM Shading-Pole Type Synchronous Motor provides reliable unidirectional rotation using shaded poles that establish a fixed preferred direction of motion. There are no additional starting circuits or capacitors required, keeping the design simple and compact.

Speed is locked to the AC supply frequency, so the motor runs at a consistent, predictable rate without relying on induction slip. Its small size and straightforward construction make it a practical choice for timing, indexing, and constant-speed applications in instruments, office equipment, and light industrial machinery where dependable one-direction rotation is all that is needed.
