Product Description:

The K32HRHJ-LSS-NS-02 is a hybrid stepper motor manufactured by Pacific Scientific for the K PowerPac Motors series. Intended for indexing tables, pick-and-place axes, and other position-based automation tasks, the unit converts drive pulses into precise angular steps without closed-loop feedback. It occupies a 3.38-inch square frame and uses a heavy-duty NEMA interface, making it suitable for motion stages where high detent and holding torque are required during idle periods.

Its rated holding torque reaches 10.8 Nm, enabling the shaft to resist load disturbances when the driver is energized but stationary. Each electrical step advances the rotor by 1.8°, and, combined with a step accuracy of ±1.5%, this supports repeatable positioning in multi-axis gantries. The motor conforms to the NEMA 34 frame standard, so couplings, gearheads, and mountings that follow this envelope fit without alteration. Internal windings are terminated in a 4-lead parallel configuration that favors lower phase inductance and higher torque at moderate speeds, and the motor uses regular leadwire connections for direct cabinet wiring. The motor operates in ambient temperatures from -20 °C to +40 °C, which supports use in lightly heated or unconditioned plant areas.

The electrical insulation system provides 100 megohms of resistance and withstands up to 340 VDC, giving the motor suitable protection against ground leakage when it is used with modern microstepping amplifiers. A laminated rotor and SIGMAX-enhanced construction increase flux density without raising loss, and the winding is standard for this series. Overall housing depth is 133 mm, and the motor uses 2 stacks in the stator layout. The motor is supplied without an internal encoder, so it is intended for open-loop positioning applications, and a standardized flange pattern simplifies alignment during installation.
