The M21NRXB-LDN-NS-00 stepper motor model is a versatile Pacific Scientific product with particular technical details that enhance the functionality, prevent injury and damage to the unit. That is, you should follow the technical information accordingly.

With the M21NRXB-LDN-NS-00, you can have either a unipolar, parallel or a series connection. Its holding torque range is between 0.68 to 0.97 +/-10% Nm. The motor’s rated current/phase at the DC is between 2.3 to 4.6 Amps. The phase resistance of the M21NRXB-LDN-NS-00 motor is 0.32 to 1.28 Ohms. Its typical phase inductance is between 1 to 4 Mh while its detent torque is 0.066 Nm. While the thermal resistance is 5.50C/watt, the rotor inertia of the M21NRXB-LDN-NS-00 motor is 0.012 kgm2 x 10-3. This motor’s estimated weight is 1.5lbs.

As a stepper motor utilizing the Sigmax Technology, the M21NRXB-LDN-NS-00 has 30mm oversized bearings that increase the motor life as well as that of the bearings. It also has the largest diameter of the NEMA 23 stepper motors making it suitable and capable of withstanding high axial and radial loads.
