Product Description:

The E21NRFT-JDN-NS-00 Hybrid Stepper Motor by Kollmorgen which is one of the leading manufacturers in hybrid and servo motors as a high quality product for use in industrial automation. This motor is from the E hybrid stepper motors line that proves the company’s assurance to the quality and innovation. This stepper motor has a NEMA 23 frame size of the diameter of 2.25 inches and its construction follows the SIGMAX standards.

The E21NRFT-JDN-NS-00 hybrid stepper motor contains the single rotor stack which provides durability during the working conditions. It provides eight lead connections with the regular construction type and lead wire connections. This model of E hybrid stepper motors provides the maximum torque at low speed. The step accuracy of this motor is +/- 1.5 % which contributes to its accuracy and each of the rotations is distributed into 200 steps. The motor is suited for challenging conditions and can operate between a temperature range of -20 to +40 degrees Celsius. The insulation type is class B which can withstand temperatures up to 130 degrees Celsius with an insulation voltage rating of 340 VDC. This hybrid stepper motor has no encode options which make it an ideal choice for applications where direct control is necessary.

The E21NRFT-JDN-NS-00 hybrid stepper motor has the low inertia rotor that is specific to the size 2 configuration which increases the motor responsiveness. The shaft configuration is provided in two forms which are either type R or type C construction. The shaft modifications are smooth which is suitable for sizes 2 and 3 with the configuration of type N. This variant is set up as a normal motor and does not come with the shaft seal.
