Product Description:

The SN32HCYR-LNK-NS-01 is a synchronous motor produced by Pacific Scientific within the Powersync Synchronous Motors series. Designed for constant-torque positioning or speed-regulated duties, the unit fits a NEMA 34 frame and mounts through a heavy-duty NEMA pattern. Its square 3.38-inch housing helps simplify panel layouts, and a System MS connector supports quick electrical connection. The construction type and special sequence both indicate a standard motor configuration. The open-loop design omits an encoder, so the motor operates without onboard feedback hardware.

Nominal electrical operation uses a line supply of 120 V AC at 50 Hz to energize the three-lead winding. Under these conditions, the motor produces a rated torque of 600 oz-in at a synchronous speed of 60 rpm. The winding draws a maximum RMS phase current of 0.64 A, and its electrical characteristics include a phase inductance of 493 mH and a phase resistance of 53 Ω. Dynamic behavior is also affected by a rated inertia of 0.52 oz-in-s², a laminated two-stack rotor, and a rotor inertia of 0.038 oz-in-s². Torque is transferred through a single shaft with a straight key, and a shaft seal helps protect the internal bearings from contaminants.

Mechanical limits allow up to 305 lb of axial load and 65 lb of radial load on the shaft without exceeding bearing ratings. At rest, the magnetic detent provides 36 oz-in of torque that must be overcome for initial movement, and the thermal path dissipates heat at 2 °C/W during steady operation. For short-term demands, the motor can deliver a pull-out torque of 870 oz-in, which gives additional margin during acceleration or when the driven load changes suddenly. These operating characteristics suit low-speed applications such as indexing tables, gate actuators, and other equipment that depends on stable synchronous motion.
