Product Description:

The M22NSXB-IDS-NS-02 is a hybrid stepper motor manufactured by Pacific Scientific within the POWERMAX II M Motors series. In industrial automation, it advances loads in fixed angular increments, allowing open-loop indexers or microstepping drives to position conveyors, labelers, and small gantries. This operating style suits applications that need repeatable starts, stops, and dwell positions without a continuously rotating servo axis. Its compact housing also helps the motor fit into small machine layouts where available mounting space is limited.

The frame follows the NEMA 23 standard, and the housing measures 2.25 in across the flats so it can mate with common motor brackets. Internally, a two-phase winding energizes eight stator teeth to produce a 1.8 degrees step, which results in 200 discrete positions per revolution. Mechanical repeatability is held within ± 1.5%, helping reduce accumulated error during long indexing sequences. A rotor made from Neodymium-Iron-Boron magnets increases pull-out torque without enlarging the motor stack. The motor uses a two-stack design, has a double-ended shaft for mounting couplings or encoders on either side, and uses no feedback, so closed-loop wiring is not required. A 30 mm bearing journal supports radial rigidity, and a receptacle connector simplifies cable attachment.

The motor uses Class B, 130°C insulation and has a dielectric rating of 340 Vdc, with an insulation resistance of 100 Megohms. These electrical values support reliable operation with typical indexing drives and help maintain separation between energized conductors and the motor frame. Continuous service is permitted from -20°C to +40°C, allowing the motor to operate in common indoor industrial environments. Enhanced construction helps the assembly resist thermal cycling that could loosen laminations during repeated start-and-stop duty.
