The Pacific Scientific Powersync Synchronous Motors series includes AC synchronous motors designed for bidirectional motion in low-speed constant-speed drive applications.
The series is built for direct operation from standard AC line voltage and is offered in NEMA 34 and NEMA 42 square-frame sizes with 60 RPM or 72 RPM versions for 50 Hz and 60 Hz systems. Available ratings span roughly 280 to 1500 oz-in of rated torque depending on frame size and electrical configuration. The design uses high-impedance serial stator windings and requires an external resistor-capacitor phase shift network for startup, while encoder provisions and factory-installed encoder options are available on selected configurations. Overall, the Pacific Scientific Powersync Synchronous Motors family is intended for applications that need precise synchronous speed, compact high-torque motor construction, and straightforward AC-powered operation.
