Product Description:
The E31NRFT-LDF-NS-00 Stepper Motor operates as a high-performance system for motion control functions. Kollmorgen produces this motor for delivering accurate and efficient operation in industrial automation. The motor arrives in a small frame of 2.58 inches (65.5 mm) but its length can differ based on chosen specifications.
This E31NRFT-LDF-NS-00 Stepper Motor generates holding torque strength that reaches 2.43 Nm for heavy-duty operations. The stepper motor receives power through rated currents that reach 8.4 A per phase. This motor consumes power based on its phase resistance value which stays between 0.13 Ohms and ±10% of that value. The stepper motor achieves optimal response times through its typical 1.1 mH phase inductance value. The measurement of thermal resistance stands at 3.9 °C/Watt which helps effective heat removal during operation. The smooth motion performance of the E31NRFT-LDF-NS-00 Stepper Motor stems from its rotor inertia measurement of 0.0586 x 10⁻³ kg-m². The weight of this motor stands at 3.2 lb (1.45 kg) which ensures proper stability for installation and use. The motor accepts side-loading up to 35 lb (156 N) as its radial shaft strength limit. High-force operations that run along the shaft axis are possible because this motor supports a maximum axial shaft load of 180 lb (801 N).
The E31NRFT-LDF-NS-00 Stepper Motor implements NEMA 42 frame architecture which enables standard mount compatibility. Option M of the construction includes the conduit connection (PG 13.5 TAP) which ensures safe wiring. The encoder mounting options depend on stack configuration because they adapt to specific integration needs. The motor has splashproof protection which allows connection through terminal boards using standards L or M. The equipment operates dependably in industrial settings where it was built to perform. This rugged design with precise specifications enables the device to work well in automation systems and motion control settings.
Frequently Asked Questions about E31NRFT-LDF-NS-00:
Q: How does the 8.4 A rated current per phase affect the performance of the E31NRFT-LDF-NS-00 Stepper Motor?
A: The 8.4 A per phase current ensures that the motor provides sufficient power for high-performance applications, minimizing performance degradation during heavy load conditions.
Q: What is the significance of the 2.43 Nm holding torque in the E31NRFT-LDF-NS-00 Stepper Motor?
A: The 2.43 Nm holding torque ensures the motor can perform heavy-duty tasks without losing position accuracy, providing reliable movement in industrial automation systems.
Q: How does the thermal resistance of 3.9 °C/Watt help in maintaining motor performance?
A: A lower thermal resistance ensures that heat generated by the motor is efficiently dissipated, preventing overheating and prolonging motor life during extended operations.
