Product Description:

The SN42HLYY-LNK-NS-00 synchronous motor is produced by Pacific Scientific and belongs to the Powersync Synchronous Motors series. As a constant-speed drive element, it locks its rotor field to the utility waveform so that mechanical rotation directly follows electrical frequency. In automated conveyors, cutters, or timing wheels, this arrangement supplies predictable angular positioning without the complexity of closed-loop feedback electronics, making it suitable for straightforward motion duty in industrial plants.

The motor accepts a single-phase supply of 120 V AC at 60 Hz, and under those line conditions the shaft turns at a fixed 72 RPM. Mechanical integration follows the NEMA 42 outline, and the square housing measures 4.325 inches in both width and height to match common face-mount brackets. A splash-resistant terminal board sits behind a conduit connector to shield terminations from washdown spray, and the absence of an encoder reduces wiring complexity in applications that require only synchronous speed accuracy. Internally, the rotor is built from thin laminated steel to minimize eddy-current heating and preserve torque stability during continuous operation. The motor relies on mains frequency for speed regulation rather than sensor feedback.

Field wiring enters through a 1/2-inch NPS pipe thread hub, which simplifies the use of liquid-tight fittings in factory environments. Mounting is handled by a heavy-duty NEMA flange that withstands higher shaft loads when the single, straight-key output is belt-coupled. Power reaches the stator through 3 leads, and electromagnetic torque is generated by 2 stacks of rotor laminations that increase axial pole area without lengthening the frame. The shaft lacks a seal, so the motor is intended for dry zones. Its single-ended design also eases alignment with gear reducers or sprockets where only one drive face is needed.
