Internal Product Review
The SN33HLYY-LNK-NS-01 is a Pacific Scientific synchronous motor with splashproof terminal-board construction for dependable industrial service. Rated torque of 690 oz-in at 72 RPM gives the motor a strong, steady operating profile for indexing and constant-speed duty. Heavy-duty NEMA mounting adds installation confidence, and 1015 oz-in pull-out torque stands out as a key performance advantage.

Product Description:
The SN33HLYY-LNK-NS-01 is a synchronous motor from Pacific Scientific and belongs to the Powersync Synchronous Motors series. Classified as a fixed-speed drive, it is intended for use in industrial automation lines where constant rotational velocity and phase integrity are required for tasks such as material indexing or metering. By running directly from single-phase mains and locking its rotor to line frequency, the motor delivers reliable, step-accurate motion without external electronic feedback components.
This model develops a shaft speed of 72 RPM, so timing stays consistent with the power grid. At that speed, it produces a continuous torque of 690 oz-in, enabling it to handle moderate static loads on conveyors or turntables. Supply power is 120 V AC, which simplifies wiring in panels that already distribute that voltage. When the load momentarily rises, the motor can sustain up to 1015 oz-in of pull-out torque before losing synchronism, giving extra margin for short surges. The square NEMA 34 frame provides a familiar mounting footprint and matches couplings and gearboxes built to the same standard.
The rotor has an inertia of 0.53 oz-in-s², so acceleration profiles can be calculated accurately for start-stop duty cycles. Line input is locked to 60 Hz, which means speed changes must be achieved through mechanical gearing rather than frequency variation. The motor uses 3 Leads for wiring, and they terminate on a splash-proof terminal board reached through a 1/2" NPS conduit thread to help maintain enclosure integrity. Laminated rotor construction, three rotor stacks, a single straight-key shaft, heavy-duty NEMA face mounting, and a fitted shaft seal support installation in environments where oil mist or light washdown is present.
