Product Description
The H21NRFT-LNN-NS-00 step motor is one among the various H21 series of hybrid step motors from Kollmorgen that offers assurance of excellent performance. The manufacturer is known for the vast selection of different types of motors in its portfolio to match just about any requirement. The step motor is 2.06” in maximum length that makes it quite compact in size. It features an IP65 construction style that makes the unit splash-proof. The motor features 0.41Nm to 0.61Nm torque range. The bearings have a long life and do not get damaged easily with regular use. They have a very small diameter of 0.25”.
The hybrid motor makes use of a laminated rotor with a unique hollow construction. This construction results in high torque to inertia ratio that makes the device best suited for various in-plant applications. It has an ideal operating temperature of 25°C. The unit supports NEMA mounting according to industrial standards through four equally spaced mounting holes. The device comes housed inside a rugged NEMA 23 circular frame of 2.25” diameter. The motor does not support any feedback and hence does not have an encoder option. Its low-mass makes the unit easily transportable.
The step motor features a warranty period of one year. The motor supports regular construction with leadwire hookup. The unit makes use of 8-lead winding leads. It also encompasses a winding type of maximum torque at low speed. The device comes with a smooth and single shaft. The hybrid motor is likely to experience loss of some flux during normal operation. The unit comes equipped with an MS connector termination. This connector termination can be used for both the motor and an encoder if it is added optionally. The motor is best suited for use in OEMs because of its highly dependable operation.
