P22NRXA-LDN-HD-00

Product Description:

P22NRXA-LDN-HD-00 is a Kollmorgen hybrid stepper motor. It is part of the PowerMax II product line. It is available in the universal NEMA 23 frame size. Magnet stack length of the motor is 2. The motor has a smooth shaft that is laminated for high efficiency. The shaft goes through 200 steps per revolution and the full step angle is 1.8 degrees. The angular accuracy is ?3% of one step at no load. Operating temperature for the P22NRXA-LDN-HD-00 motor is -25 to 40 degrees Celsius. The insulation class is B rated for 130 degrees Celsius. The insulation resistance is 100 megahoms at 500 Volts DC and 25 degrees Celsius. Maximum radial load for the shaft is 20 pounds at center of the standard shaft extension. The maximum axial load is 13 pounds on the front shaft extension toward the motor.

As large 30 millimeter bearings are used, the operating life is about four times that of smaller bearings used on other NEMA Size 23 motors. The motor bearing fatigue life exceeds 10,000 hours at all rotational speed up to 10,000 full steps/second if operated within the maximum radial and axial load limits. Weight of the P22NRXA-LDN-HD-00 motor is 1.13 kilograms. The rotor inertia is 0.0036 kg m2. Thermal resistance of the motor is 4.5 degrees Celsius per Watt. The detent torque is 0.049 Nm. The holding torque is 197 Nm in parallel and series configuration and 139 Nm in unipolar configuration. The rated current per phase is 6.5 Amps DC for parallel, 3.3 Amps DC for serial and 4.6 Amps DC for unipolar configuration. The motor is designed for professional handling, installation and maintenance.
