Product Description:

The K32HLHJ-LNK-NS-00 is a stepper motor produced by Pacific Scientific for the K PowerPac Motors series. This motor converts digital pulse trains from indexers or PLC drive stages into proportional angular displacement, providing open-loop positioning in material handling and light machine-tool axes where servo feedback is unnecessary. It belongs to the manufacturer’s heavy-duty line and uses SIGMAX enhanced construction to increase flux density for higher torque per frame size.

This model fits a 3.38 in. square frame and conforms to the NEMA 34 mechanical standard, allowing direct interchange with common gearboxes or mounting brackets. Its rotor stack measures two laminations deep, resulting in a motor length of 133 mm and a holding torque of 10.8 Nm. A laminated rotor core limits eddy losses, while a single shaft with a straight key transmits torque without backlash; the shaft has no seal, so external protection is required in washdown zones. Power reaches the windings through a splash-proof conduit connection that terminates on a board inside the housing, and the entry port uses a 1/2 in. NPSC pipe thread. Internally, a standard winding set is arranged for a 4 lead parallel connection, and insulation is rated for 340 Vdc to withstand high-energy micro-stepping drives.

The thermal envelope extends from -20 °C to +40 °C, so the motor can operate in unheated warehouses or ventilated cabinets without derating. An insulation resistance of 100 megohms minimizes leakage currents during high-humidity starts, and the motor is supplied with no feedback option for installations that rely solely on commanded step counts. Positional repeatability is supported by a step accuracy of ±1.5 %, while each electrical sequence advances the shaft by a precise 1.8 ° step angle, enabling straightforward resolution calculations when sizing lead-screw or belt drives.
