Product Description

The M21NRXB-LSS-NS-03 M series stepper motor features SIGMAX technology and is marketed under the POWERMAX II brand name. The hybrid motor features a polymer end bell with threaded inserts. This end bell is responsible for running the cooler as well as offering high flexibility in mounting the brake and encoder. It also enhances the life of the encoder with its cooler operation. The device has receptacle style termination. It features an angular accuracy of +/-1.5% of a full step with no load. The unit encompasses an insulation resistance of 100 Megohms at 25°C and 500VDC. The product is a good choice for applications with special acceleration requirements. The motor can be dispatched globally through our trustworthy delivery team.

The stepper motor has a size of 2.25 inches across flats corresponding to NEMA 23 size. The motor implements NEMA mounting style with one stack for the rotor. It has a standard laminated rotor, a regular construction style and a winding type of B. The unit has a step angle of 1.8°C. The product has a holding torque of 1.79Nm with both phases on and parallel to each other. The device is capable of operating at an ambient temperature range of -20°C to +40°C. The life of the large bearings is 400% more when compared to that of standard 22mm bearings.

The hybrid motor can be mounted using four mounting screws placed at an equal distance from each other. The device has rotor inertia of 0.025kgm² x 10^-3. It features high-speed efficiency and excellent thermal dissipation. The product is a good option for table drives because of the constant load. When the unit is used with a flexible coupling, it can be used for producing improved torque. The motor has a high torque to inertia ratio and economical design.
