M21NRXA-JDN-NS-00

M21NRXA-JDN-NS-00 is a Pacific Scientific unit in the POWERMAX II M Motors series. It has an enhanced construction, a NEMA 23 frame, and a NEMA mounting style for installation in compatible mounting patterns. The motor is 2.06 inches (52.3 mm) long and weighs 1.5 lb (0.68 kg). Its low-inertia rotor supports rapid changes in speed, while the single-stack design provides the motor’s compact configuration. Winding type A determines its electrical winding arrangement.

The motor has a 1.8-degree step angle and completes 200 steps per revolution, providing incremental positioning. Step accuracy is ±1.5%. The encoder option is no feedback, so the motor does not provide encoder-based position data. Its regular leadwire connection style provides direct wiring, and its connection provision is a receptacle.

The double-shaft configuration provides access at both ends of the rotor. The front shaft is 0.81 inches (20.60 mm) long, and the rear shaft is 0.75 inches (19.1 mm) long. The shaft diameter is 0.2500 inches (6.35 mm), and the smooth shaft supports coupling attachment without a keyway. The shaft supports an axial load of 13 lb (58 N) and a radial load of 20 lb (89 N).

Class B insulation is rated for 130ºC. The insulation resistance is 100 megohms for electrical isolation, and the insulation voltage rating is 340 VDC. The operating temperature range is -20ºC to +40ºC.
