Product Description:

Kollmorgen manufactured the high-performance stepper motor designated as E2HNRHB-LNF-NS-02. The motor delivers precise motion control operations that make it appropriate for industrial automation systems and robotic applications. Advanced applications obtain remarkable performance, which extends both durability and efficiency features.

The E2HNRHB-LNF-NS-02 stepper motor has a shaft dimension of 0.3750 inches (9.53 mm) plus 0.0000 and a tolerance range of -0.0005. The circular mounting space has an outer dimension of 2.186 ± 0.002 inches and it measures 55.52 ± 0.051 mm. The motor requires a minimum of 12.0 in [304.8 mm] for the lead wire length. The motor accepts 35 lb (156 N) of radial shaft load. The motor accepts 180 pounds of axial shaft load (801 Newton). This motor has a rotor inertia value of 0.120 kg-m² which equals 0.017 oz-in-s². The motor produces heat dissipation through thermal resistance with an operation rate of 2.7°C/Watt. The phase resistance reaches 0.19 Ohms ±10% per specification. The phase inductance measure of this E2HNRHB-LNF-NS-02 stepper motor typically reaches 2.4 mH. The motor operates at 8.1 Amps as its rated current when working in parallel mode. The component provides a holding torque performance of 471 oz-in (3.33 Nm). The device uses an L-type conduit connection which provides reliable wiring security.

The E2HNRHB-LNF-NS-02 stepper motor serves applications that need precise control of high torque systems. A round mounting configuration characterizes this system which does not exist in 3-stack motors. The device maintains durability because of its strong build design which performs well under challenging conditions. Customers can choose to install the encoder mounting for increased installation versatility. The motor can function in many different industrial environments. The product has wide applications in CNC machines, automated manufacturing, and robotics.
