Product Description:

Pacific Scientific's SN34HLYY-LNK-NS-00 is a synchronous motor built for constant-speed, torque-rich motion in the Powersync Synchronous Motors series. As a standard motor for industrial automation, it couples directly to low-speed conveyors, mixers, or rotary indexes where a precise 60 Hz line frequency can be used to lock rotor position without electronic feedback. The heavy-duty NEMA mounting pattern and splash-proof terminal board allow the unit to be installed in production environments that need simple, durable drive components.

Electrically, the motor reaches a shaft speed of 72 RPM from a three-lead stator powered by a single-phase 120 V AC source. At 80% of pull-out, it draws 1.43 A; the winding has 16 Ω of resistance and 191 mH of inductance, which support a pull-out capability of 1520 oz-in. The square 3.38-inch frame conforms to the NEMA 34 envelope, and its laminated four-stack rotor with 0.075 oz-in-s² inertia works with a 0.53 oz-in-s² load inertia rating for smooth acceleration. A 1/2-inch NPS conduit thread mates with rigid conduit to preserve the splash-proof construction. The design includes no integrated shaft seal, no encoder feedback, and a single straight-key shaft, yet the housing tolerates 110 lb of radial force because of its heavy bearings.

The motor can deliver a continuous torque of 900 oz-in, while the detent characteristic supplies 57 oz-in of passive holding force when power is removed. Bearings support up to 305 lb of axial thrust without accelerated wear, making the unit suitable for vertical loads. Thermal management uses a resistance of 1.3 °C/W, allowing heat generated by I²R losses to move through the cast housing and laminated rotor. With splash-proof construction, heavy-duty NEMA mounting, and a standard winding sequence, the motor fits conduit-fed panels that require low-speed constant-torque performance.
