Product Description:
The M22NSXD-LNN-NS-02 hybrid stepper motor is produced by Pacific Scientific as part of the POWERMAX II M Motors series. It provides incremental rotary motion in feeders, small conveyors, and similar automation equipment where digital pulse trains are converted into repeatable shaft positions. Because it is a hybrid stepper motor, it is suited to applications that need discrete positioning without a closed-loop servo system. The motor uses a NEMA mounting interface in a NEMA 23 frame and has two stator stacks, giving it a compact format for controlled indexing tasks.
The motor uses D winding and can be wired in parallel for 2.5 A DC per phase or in series for 1.2 A DC. In parallel, the phase resistance is 1.22 Ω, while series connection raises resistance to 4.87 Ω; the corresponding inductances are 5 mH and 19.9 mH. When energized, the motor delivers 1.68 N·m of holding torque, while detent torque is 0.12 N·m with the windings off. The insulation system is rated Class B 130 °C, with 100 megohms to ground and a 340 VDC dielectric margin. The motor is supplied with no feedback, so it is intended for open-loop operation, and step accuracy remains within ±1.5%. It can operate at speeds up to 3000 RPM, and the receptacle-style connector provides the electrical interface for power connection.
The smooth single shaft tolerates 58 N of axial load and 89 N of radial load, making it suitable for moderate belt or gear drive tensions. These load limits are suitable for light transmission elements that do not place excessive side force on the bearings. Rotor inertia is 0.0000252 kg·m², which supports quick acceleration with a standard rotor. Each input pulse turns the shaft by 1.8 degrees, giving 200 steps per revolution for fine indexing. Ambient operation is permitted from −20 °C to +40 °C, and no additional mechanical features are included on the shaft or frame.
