The M21NRXD-LNN-NS-00 stepper motor from Pacific Scientific is part of the POWERMAX II M Motors series. It features a NEMA 23 frame size, a 1.8-degree step angle and holding torque of 79-111 oz-in (0.55-0.78 Nm), and operates on two-phase power delivery. The low inertia rotor enables rapid speed changes and it meets IEC IP65 sealing for dust and water protection. This motor functions reliably between -20°C and +40°C.
