Product Description:
The SN32HLYY-LNK-NS-01 is a synchronous motor produced by Pacific Scientific for the Powersync Synchronous Motors series. Operating directly from 60 Hz utility power, the unit provides constant low-speed rotation for indexing tables, mixers, and conveyor sections where an electronic drive is not required. In industrial automation, it converts single-phase mains power into accurate mechanical timing, and its heavy-duty NEMA mounting supports installation in equipment that uses the same frame style. Because the rotor locks to line frequency, normal operation provides repeatable speed without the need for a variable-frequency controller.
The motor is designed for direct connection to a single-phase 120 V AC source, and its three-lead winding creates the phase shift needed to start and maintain synchronous operation at 72 RPM. Continuous output reaches 480 oz-in of torque, while pull-out torque is 690 oz-in and detent torque is 36 oz-in to help reduce hunting at rest. A heavy-duty NEMA mount, a NEMA 34 frame measuring 3.38 inches square, and a 1/2 in. NPS conduit entry support installation, while the splash-proof terminal board and IP65 sealing help protect the motor in washdown areas. The unit also uses standard construction, laminated rotor stacks, a single straight-key shaft, and a shaft seal that protects the internal bearings. A straight-key shaft allows the motor to couple to common driven loads.
Electrical characteristics include a phase inductance of 383 mH and a phase resistance of 38 ohms, which help support stable synchronization with the motor's rotor design. At 80% of pull-out torque, each phase draws 0.47 Arms/phase, and that value is useful when selecting power relays and thermal overload protection. The required 10 µF capacitor supplies the lead angle needed for startup, while a 200-ohm resistor limits inrush current. Rotor inertia is 0.038 oz-in-s², and two rotor stacks increase saliency for steady running under load. No feedback device is installed, so any position sensing must be provided externally.
