Product Description:
This E21NRFT-JNN-NS-00 is a reliable Stepper Motor that finds use in various drive operating applications. This motor comes from Kollmorgen which maintains trust in the industrial automation arena through advanced components that meet customer-centric operations and active industry-leading performance standards.
The E21NRFT-JNN-NS-00 stepper motor produces its power at eight winding points with eight specific conductors to enable series, parallel and unipolar connections for enhanced rotational torque and velocity optimization. The stepper motor accomplishes diverse operations using its single rotor stack and provides torque between 0.54 Nm to 0.77 Nm. These stepper motors come in NEMA 23-type casing with the addition of Sig-max technology to deliver superior torque at different speeds. An optimal and swift working torque at both high and low speeds is achieved through this performance-enhancing feature. The motor achieves a 123 oz-in holding torque of 0.87 Nm when supplied with 1.39 A DC through a series configuration yet further torque stability for complex motion tasks can be obtained with 2.8 A DC in parallel mode. This motor operates until 1500 rpm while receiving drive systems through 65 V input voltage.
The E21NRFT-JNN-NS-00 stepper motor’s 48 W power rating provides efficient power utilization and lead-wire connections simplify diverse controls setup integration. The motor is highly regarded for the purpose of accepting several different 4 to 8-type lead wiring configurations because it provides users the flexibility to gain specific electrical specifications. The motor operates extremely well within a -20°C to 40°C temperature range for reliable application execution. An exceptional application choice results from the integrated 0.55 Kg weight setup which improves efficiency by means of balanced power delivery.
