Product Description

The H21NRFB-LNN-NS-00 item code refers to a stepper DC motor manufactured by Kollmorgen. This is a hybrid motor manufactured on the basis of the conventional standards. Kollmorgen has incorporated hybrid low inertia technology into this motor. The H21NRFB-LNN-NS-00 motor produces 0.02 Nm torque. This motor can handle DC current of 0.71 amperes. The weight of this motor is about 0.55 kg or 1.2 pounds. The manufacture of this motor was previously done by Pacific Scientific but now, has been acquired by Kollmorgen Inc. All products made by Pacific Scientific have been rebranded in the name of Kollmorgen Inc, which is an American company. It manufactures the electronic and electrical products used in the industrial automation and motion control solutions.

The H21NRFB-LNN-NS-00 stepper motor is single stack motor manufactured on the standard NEMA 23 design. This motor has NEMA mounting option. The construction of this motor is regular as indicated by the R followed by the FB. The F shows the types of connection, which are 8 leads. The type of windings used in the H21NRFB-LNN-NS-00 motor is referred to as the B type as shown by the B in the commercial product name. The rotor of this stepper motor is standard laminated and connected with a single front shaft. The shaft type is shown by the N in followed by the N, which indicates the shaft modification.

The H21NRFB-LNN-NS-00 stepper motor has no encoder option, which means this motor cannot be connected to the feedback system as shown by the NS in the commercial code. The last pair of zeros in the item code shows the type of special sequence. This stepper motor has not been designed with any kinds of customizations.
