Product Description:
The M22NSLB-JDS-NS-02 is a hybrid stepper motor produced by Pacific Scientific within the POWERMAX II M Motors series. Supplied in a NEMA mounting format, this motor converts digital command pulses into discrete angular movement for indexing, conveying, or light machining axes in industrial automation. Its enhanced magnetic circuit and double-ended shaft support couplings or auxiliary devices while maintaining a compact profile. Because it is a hybrid stepper design, the motor is suited to applications that need repeatable incremental motion with straightforward pulse-based control. This makes it suitable for compact equipment where mounting space is limited.
Each full step covers 1.8 degrees, and with 200 mechanical steps per revolution, the rotor provides consistent resolution without microstepping. Actual step placement has a tolerance of ±1.5%, which helps limit cumulative position error during repeated indexing moves. The motor uses a two-phase winding, and the stator has 2 energized phases wound to pattern B and brought out through a four-lead series connection for bipolar drive wiring. A square NEMA 23 frame that measures 2.25 in. wide supports use with common brackets, while a dual-stack lamination core increases torque density. Thermal integrity is supported by insulation rated to Class B, 130°C, which helps protect the winding system as case temperature rises during cyclic duty.
The rotor uses a low inertia design, allowing rapid acceleration so high pulse rates can be tracked with reduced overshoot. Electrical isolation is supported by an insulation resistance of 100 Megohms and a dielectric limit of 340 VDC between the windings and frame, which helps protect the motor in grounded machine assemblies. Continuous service is permitted in ambient air from -20°C to +40°C, matching typical factory conditions. The enhanced construction improves magnetic saturation while keeping the overall length moderate, and the double-ended shaft allows one end to drive the load while the opposite end can accept a manual jog wheel or secondary coupling. No feedback device is fitted, so position control depends on commanded step pulses rather than encoder signals.
