Product Description

P21NRXB-LSS-NS-05 is a Hybrid Stepper Motor from KOLLMORGEN. This model is designed to comply with the frame size and mounting requirements as of the NEMA 23. The P21NRXB-LSS-NS-05 is a highly efficient motor and it is widely used in critical industrial applications. This stepper motor has 1 rotor stack and its step angle resolution is 1.80 degrees/step. This POWERMAX® P Series motor can offer a maximum holding torque of 111 oz.-in. The P21NRXB-LSS-NS-05 is available in bipolar series and bipolar parallel configurations.

For connections, this motor comes with an 8-pol receptacle. This stepper motor is intended to be used with an appropriate stepper drive controller. In its default configuration, the drive comes without a feedback encoder. However, you can acquire an optional encoder separately from the vast range of optional products KOLLMORGEN offering for its POWERMAX® P Series products. The P21NRXB-LSS-NS-05 is a CE compliant and UL recognized motor. In case if you are looking for a motor with a higher acceleration rate and better torque than you can go with the low inertia rotor variant of this stepper motor.

The stator of the P21NRXB-LSS-NS-05 is polymer encapsulated – a feature that helps in the optimization of thermal dissipation. The polymer end bell provides the user with better flexibility for mounting brake and encoder options. At 25 degrees centigrade temperature, the phase resistance of this motor remains around 1.26 Ohms and its phase inductance remains around 4/60mH. The P21NRXB-LSS-NS-05 is a 2.06-inch sized motor and its weight is 3.31 lbs. Being one of the most reliable options, this stepper motor, and its other variants are often found in the medical and aviation industry. This model has 2 x 30 mm bearings.
