Product Description

M21NRXA-LSN-M1-03 is a Pacific Scientific motor in the POWERMAX II M Motors series. It has an enhanced construction, a NEMA 23 frame size, and a NEMA mounting style for installation on compatible equipment. The motor measures 2.25 inches across the flats and has a maximum body length of 2.06 inches. It weighs 1.5 pounds.

The two-phase motor uses winding type A and has one stack. Its standard rotor has an inertia of 0.0017 oz-in-s², while the detent torque is 9.4 oz-in. A 1.8-degree step angle produces 200 steps per revolution, and the step accuracy is ±1.5%. The smooth shaft has no keyed or flat modification. An encoder mounting provision allows a compatible encoder to be installed.

The motor uses a regular leadwire connection style and a receptacle connection. Its Class B insulation is rated for 130ºC, the insulation resistance is 100 megohms, and the insulation voltage rating is 340 VDC. Thermal resistance is 5.5ºC/W, indicating the temperature rise per watt of dissipated heat. The operating temperature range is -20ºC to +40ºC.
