Product Description:

The SN32HMYW-LNK-NS-00 is a synchronous motor produced by Pacific Scientific and supplied within the Powersync Synchronous Motors series. It delivers a fixed mechanical speed that follows line frequency, so it is selected for indexing tables, metering pumps, and other automation stages that cannot tolerate speed drift. The motor has a splash-proof terminal board accessed through a metric PG11 conduit connector, enabling direct wiring into sealed enclosures for use in washdown or dusty production areas.

The motor is wound for 240 V AC operation on a 50 Hz supply and draws 0.29 A per phase at 80% of pull-out torque. Its three-lead winding shows a phase inductance of 1345 mH, an attribute that smooths current rise and reduces torque ripple at the low synchronous speed of 60 RPM. With a rated torque output of 600 oz-in, the unit can sustain a constant load while remaining within its thermal range. The frame meets the NEMA 34 outline, giving a 3.38-inch square housing that mates with standard heavy-duty NEMA mounts. Rotor inertia is 0.038 oz-in-s², while the reflected inertia at the shaft is 0.5 oz-in-s², supporting responsive but stable motion.

The motor can achieve a pull-out torque of 825 oz-in for brief overloads without losing synchronism, and the detent torque of 36 oz-in must be overcome when the shaft is unenergized. Bearing supports allow up to 305 lb of axial load and 65 lb of radial load, so couplings or gears can be mounted directly on the single, straight-key shaft. Copper windings present a phase resistance of 143 Ohms, and heat leaves the stator through a thermal path rated at 2 °C/W, which affects temperature rise during stalled or high-load duty. The laminated two-stack rotor, the absence of a shaft seal, and the lack of feedback devices keep the assembly simple for standard process drives.
