Product Description

The item code number H21NRFC-LNN-NS-00 denotes a single stack stepper motor. This single stack motor is manufactured by Kollmorgen, an American manufacturer of electrical and electronic equipment and manufacturers many products used in the motion control systems.

The H21NRFC-LNN-NS-00 commercial item code specifies different features and capabilities of this motor. For instance, this motor has no encoder options or the motor has no option for connecting with the feedback system as shown by the NS in the product code. The last 00 indicate that this stepper motor has no special sequence. Adding any special sequence means the customized addition of systems or parts. The H21NRFC-LNN-NS-00 motor is designed in accordance with the NEMA 23 industry standard for the H series category of motors as denoted by the 2 before the H in product code.

The H21NRFC-LNN-NS-00 operates on the DC voltage and produces volume of detent torque equal to 0.02 Nm. This motor uses the type C windings as shown by the C in the code. These windings can handle current of 2.9 amperes. The frame size of this motor is 2.25 inches dia. This motor takes 200 equal steps of 1.8 degrees to complete one single revolution. The rated accuracy of the step in the specified operating conditions is ±3% of the distance of the step. The connection type of this stepper motor is 8 flying leads while the frame design is regular. The rotor of this motor is formed of the laminated strips of the magnetic material.
