Product Description:
The P21NRXC-LDN-M1-00 is a hybrid stepper motor built by Pacific Scientific for the POWERMAX II P Motors series. Classified as a NEMA-form-factor motion device, it converts index commands from a drive into discrete rotational movement for positioning tables, small loaders, and actuators on automated lines. The motor supplies incremental torque through its internal permanent-magnet rotor and stator teeth, allowing open-loop control systems to hold or advance mechanical loads without feedback. This operating principle provides repeatable movement when the selected drive supplies the correct phase current and pulse sequence.
The motor uses a NEMA 23 frame, so its housing aligns with common 2.3-inch square mounts. Its full-step angle of 1.8 degrees provides predictable angular movement, and the motor completes one revolution in 200 full steps. Positioning error remains within ±1.5% of one step. A single lamination stack, standard rotor, and smooth shaft help limit reflected inertia and vibration during acceleration. The stator wiring exits as standard lead wires terminated at a receptacle, allowing connection to the motor drive. The windings use Class B insulation rated for 130 °C to resist thermal stress during operation. A dielectric withstand rating of 340 V DC provides insulation margin between the energized windings and the motor frame. The C-type winding is suitable for use with compatible bipolar stepper drives. A machined rear provision accepts an encoder when an application requires position feedback or stall detection.
The insulation resistance measures 100 megohms between the windings and frame, helping minimize electrical leakage. The ambient operating range extends from -20 °C to +40 °C, permitting use in unconditioned industrial cabinets within those temperature limits. A double-ended output shaft extends through both end bells, allowing an encoder or secondary mechanical load to be attached without a shaft adapter. Winding code C indicates the resistance and current characteristics used when matching the motor to an appropriate drive. The receptacle connection keeps the electrical interface compact, while the smooth shaft supports clamping couplings that do not require a keyway. Its open-loop design can maintain holding torque at standstill when the drive continues supplying the required phase current.
