Product Description:
The P21NSXS-LSS-M1-02 belongs to the POWERMAX II P Motors series produced by Pacific Scientific. It is a two-phase positioning motor intended for incremental motion tasks in industrial automation, where moderate torque and repeatable step execution are required for indexers, small gantries, and similar axes. Each command pulse produces a fixed angular movement, which makes the motor suitable for applications that need consistent step-to-step positioning without a complex motion platform. The unit follows a NEMA mounting convention, so it fits machine layouts built around that standard.
The motor advances in discrete increments of 1.8 degrees, and one full revolution equals 200 steps per revolution. This arrangement gives the controller a direct relationship between pulse count and shaft position during basic positioning tasks. Positional error during each move is limited to ±1.5% step accuracy, supporting repeatable placement when the load remains stable. Its electromagnetic circuit uses 2 phases, allowing standard bipolar or unipolar drivers to energize the windings. A single stator stack keeps the body compact, while the standard rotor profile helps maintain consistent detent behavior. System wiring connects through a receptacle, and the housing also allows encoder mounting when added feedback is required.
Mechanical installation uses the NEMA 23 frame outline with a matching NEMA face, and the standard body can be fastened directly into machinery. Thermal capability is supported by Class B, 130 °C insulation. The windings have an insulation resistance of 100 Megohms at room conditions and can withstand up to 340 Vdc between active parts and the frame. Continuous operation is permitted from -20 °C to +40 °C, which suits many cabinet-mounted and general industrial environments. The one-stack layout also helps keep the motor compact where installation space is limited.
