Product Description:

The E31NRHT-LNN-NS-00 stepper motor is designed for commercial applications. It is a part of the E Hybrid Stepper Motors Series. This motor is engineered to generate substantial power and operate seamlessly. It possesses a greater flux concentration due to the utilization of SIGMAX technology. The motor ensures optimal low-speed torque delivery.

The Kollmorgen E31NRHT-LNN-NS-00 stepper motor generates 349 oz-in of power. It features 200 steps per rotation and a step angle of 1.8°. Each stage in the control process is accurate to within 1.5%. For heavy-duty motion operations the rated speed can reach 1500 rpm. A 3.38" x 3.38" NEMA flange is utilized for installation. The motor frame has a width of 3.38 inches, that allows for proper mounting. The pitch circle diameter is 3.875 inches to ensure a robust structural fit. The motor has Class B protection and weighs two pounds. Its design includes a smooth shaft and a laminated rotor frame. The moment of inertia is 0.586 kg/cm². This stepper motor features a T-type winding. This winding generates the majority of the power at slower speeds. When connected in parallel, the maximum current is 5.4A. It uses four parallel lead lines to ensure a stable connection. The motor can support a maximum radial load of 156 N. It can also support up to 801 N of axial load. Holding torque is rated at 2.38 Nm when wired in parallel. For constant resistance, the detent torque is set to 0.16 Nm.

The E31NRHT-LNN-NS-00 stepper motor integrates precision with endurance. It offers higher acceleration rates using enhanced stator technology. It facilitates uniform torque with optimization at low speeds. The E series promotes economic efficiency by minimizing internal losses. Its spherical design suits both compact and industrial setups with ease.

Frequently Asked Questions about E31NRHT-LNN-NS-00:

Q: What is the benefit of using SIGMAX technology in the E31NRHTLNNNS00 motor?

A: SIGMAX technology improves magnetic flux concentration, enabling higher torque density. It also enhances efficiency by reducing core losses during operation.

Q: How does the T-type winding in E31NRHTLNNNS00 optimize torque at low speeds?

A: The T-type winding increases magnetic interaction at lower frequencies. This results in improved low-speed torque and smoother startup performance.

Q: How does the smooth shaft design of E31NRHTLNNNS00 impact coupling performance?

A: A smooth shaft ensures uniform load distribution when coupled with external systems. It reduces mechanical wear and enhances alignment precision.

Q: What role does the laminated rotor play in the E31NRHTLNNNS00 motor’s performance?

A: The laminated rotor minimizes eddy current losses. This increases thermal efficiency and allows consistent torque output over extended use.

Q: Why is the E31NRHTLNNNS00 rated with Class B insulation?

A: Class B insulation supports operation up to 130°C. This allows the motor to function in moderately high-temperature environments without insulation breakdown.
