K43HRFK-LNK-NS-00 by Pacific Scientific

The Pacific Scientific K43HRFK-LNK-NS-00 motor is a robust member of the K PowerPac Motors series, engineered by Pacific Scientific for demanding industrial automation tasks. With a holding torque of 39.9 Nm (5700 oz·in) and a nominal voltage of 170 V, this NEMA 42 frame motor delivers precise motion control in parallel configuration. Its rated current per phase of 3.1 A ensures consistent torque delivery for positioning and motion control applications in machinery and robotics.

Featuring a heavy-duty NEMA mounting design, the K43HRFK-LNK-NS-00 offers a 4.325 in. square frame and an 8-lead leadwire configuration for flexible wiring arrangements. The laminated rotor design minimizes eddy current losses and enhances dynamic response, while the single straight-key shaft supports reliable mechanical coupling. Insulation is rated to 340 Vdc, safeguarding the motor windings against voltage spikes. With a thermal resistance of 118 °C/watt, this motor efficiently dissipates heat under continuous operation.

Additional features include an encoder supply voltage of 5 VDC ±10% with a differential line drive output, providing robust feedback signal integrity and noise immunity. The motor’s straight-key shaft design simplifies integration with standard couplings and gearboxes, while the absence of a shaft seal reduces maintenance points. Rated at 308 W of power output, this motor delivers energy-efficient performance. Its rugged frame type and laminated rotor ensure durability, making it ideal for high-precision industrial automation, robotics, and motion control systems where reliability and efficiency are paramount.
