H21NRFA-LNN-NS-00

Product Description

The H21NRFA-LNN-NS-00 is the commercial code for a Kollmorgen stepper motor. This stepper motor was designed and made by Pacific Scientific Inc, which was an American company. But, now Pacific Scientific has been merged into Kollmorgen Inc, another very well known manufacturer of electrical motors and motion control solutions. Kollmorgen Inc is also an American company. This company has presence in almost all major countries and regions around globe.

The H21NRFA-LNN-NS-00 is an important member of H series stepper motors. This stepper motor uses hybrid inertia technology and offers great performance. This stepper motor is a single stack motor. The frame design is based on the NEMA 23 standard. As the construction is based on the NEMA design so the mounting of this motor is also based on the NEMA standard as mentioned by the N followed by the RFA. The regular construction, connection termination by 8 flying leads, and the A type of windings are used in this motor as denoted by the RFA respectively in the item code.

The H21NRFA-LNN-NS-00 motor runs on DC power. At the end of every single step the power direction is reversed to produce another step of movement in the rotor. This stepper motor completes one single cycle in two hundred steps of equal size. The average distance covered in a single step is 1.8 degrees with accuracy of ±3% of the original distance. This motor uses standard rotor design, single shaft, and the design of the single shaft is smooth without any additional modifications as denoted by the LNN in the commercial code of the product. The H21NRFA-LNN-NS-00 motor has no additional customization.
