Product Description:

Kollmorgen's H32NRFA-LNN-NS-00 Hybrid stepper motor is designed to excel in automation applications that require great performance in industrial settings. Precision and adaptability are its features, thanks to cutting-edge features such as low inertia designs and excellent torque generation. Sigmax® Technology that utilizes rare-earth magnets, increases both the motor's efficiency and torque.

The H32NRFA-LNN-NS-00 hybrid motor has a rated current of 8.1 A DC. The motor has 2.4 mH inductance and 0.19 ohms phase resistance guaranteeing steady and effective operation. It is possible to achieve accurate control with the motor's holding torque of 471 oz-in (3.32 Nm). The motor shows rapid reaction in dynamic applications with a rotor inertia of 9.6 oz-in³ (kgm² x 10⁻³). Additionally, the motor's designs that have a low inertia are suitable for applications that require extremely quick acceleration. The H32NRFA hybrid motor is fully compatible with a wide range of stepper drives due to its unique feature that it is equipped with both bipolar and unipolar driving options. In industrial automation, these characteristics work together to guarantee efficient and dependable operation.

The H32NRFA-LNN-NS-00 hybrid stepper motor is unparalleled in terms of torque and efficiency. The motor is intended for use in both high-performance and low-inertia applications. The high torque density and low resistance of the motor are some of the factors that contribute to its efficiency. With a phase resistance of 0.19 ohms and a rotor inertia of 9.6 oz-in-cubic inches (kgm2 x 10⁻3 inches), the motor ensures both stability and rapid movement. It is able to perform its function on a consistent basis even in severe industrial situations. The motor provides a high level of precision and is meant to be adaptable.
