Product Description:
The P21NSXS-LSS-NS-06 stepper motor is produced by Pacific Scientific within the POWERMAX II P Motors series. In automation equipment, it converts command pulses from an indexer or drive into incremental rotary motion, enabling small gantries, feeders, and specialty machinery to position loads repeatably without external motion sensors. The motor uses standard construction, routes power through a receptacle, includes no feedback device, and maintains a compact length.
Mechanical proportions start with the NEMA 23 frame size, giving a square 57 mm face that matches many compact gearboxes. The case width is 57.10 mm, and the motor uses a single lamination stack. Motion resolution originates from the 1.8-degree basic step, producing 200 discrete positions per revolution. Position error stays within ±1.5 %. Two electrical phases are sequenced by the controller, and the special winding code sets the current profile required for torque. A standard rotor couples to a special shaft configuration for nontraditional couplings. This fine granularity simplifies gear ratio selection and permits direct drive of moderate loads. Because each move is predictable, the motor can meet repeatability requirements without complex feedback algorithms.
Mounting data completes the profile. A 38.10 mm pilot centers the housing, while the bolt circle spans 66.67 mm and each mounting hole is 5.08 mm in diameter. The arrangement complies with the NEMA mounting style for straightforward interchange, and the layout, coupled with the pilot diameter, helps maintain concentricity and prevent misalignment during torque reversal. The electrical insulation is Class B (130 °C) and withstands up to 340 Vdc between the windings and frame, with an insulation resistance of 100 megohms. Ambient operation is supported from -20 °C to +40 °C, allowing installation in chilled storage or moderately heated lines without derating. The generous voltage margin supports use with modern microstepping drives, while the high insulation resistance helps guard against moisture-induced leakage.
