Product Description:
Bearing the part number K32HCHK-LNK-NS-00, this unit is a stepper motor manufactured by Pacific Scientific for the K PowerPac Motors series. By energizing its stator phases in sequence, the motor advances a fixed angle per pulse, letting OEM machinery achieve repeatable positioning without a feedback loop. This makes it suitable for feeders, small gantries, and metering pumps in automated lines.
Electromagnetically, the two-stack design works with standard windings and a 4-lead parallel hookup to reduce phase resistance and permit higher drive currents. It produces a holding torque of 10.8 Nm, giving firm stall capacity when the shaft is energized but locked. Each command step moves the rotor by 1.8°, and cumulative deviation stays within ±1.5%, so repeatability remains tight across a full revolution. SIGMAX-enhanced construction lowers magnetic reluctance, while the laminated rotor minimizes eddy losses. An insulation system tested to 340 Vdc withstands drive transients, and insulation resistance of 100 Megohms confirms winding integrity under humid operating conditions. System MS connectors speed installation, and the absence of an internal encoder reflects the no-feedback configuration typical of high-torque steppers.
Mechanically, the motor fits within a 3.38 in. square frame that matches the NEMA 34 standard, and its length of 133 mm helps deliver the required magnetic path without increasing footprint. A heavy-duty NEMA flange provides rigid mounting, while the single shaft with a straight key simplifies coupling to pulleys or couplers. Because the design ships without a shaft seal, the bearing area should be protected when fluids are present. Continuous use is supported from -20 °C to +40 °C, which aligns with typical factory-floor enclosures. The motor relies on standard windings and the laminated core to keep heat generation low, and the two-stack construction helps maintain step accuracy even without feedback.
