Product Description

This model SRF3744-5487-84-5-56-BC is an industrial grade DC Motor integrated with a robust gearbox assembly designed for heavy duty applications. This DC motor features a cylindrical blue painted body with a ventilation cover at the rear to aid in heat dissipation.

The Kollmorgen SRF3744-5487-84-5-56-BC DC motor has been engineered to function continuously. The motor housing incorporates an electrical connection station within its terminal box mount located on top. A threaded conduit entry is available that allows easy integration into industrial control systems. The motor functions at 560 W rated power with 3.8 A current consumption. It features a permanent magnet field that provides stable magnetic flux for efficient energy conversion. Attached to the motor is a heavy duty right angle gearbox with a rectangular ribbed housing designed to enhance structural rigidity and heat dissipation. The gearbox is coated in white paint. The flanged mounting system provides stability and ease of installation in various machinery setups. The output shaft of the gearbox is equipped with a coupling assembly featuring bolts and lock washers. This ensures secure torque transmission and minimizes backlash. The shaft of this motor is keyed. The gearbox has provision for lubrication that is essential for maintaining smooth gear operation and reducing wear over time.

The SRF3744-5487-84-5-56-BC DC motor maintains a constant operating speed at 1750 rpm while employing an insulation class H. The insulation Class H enables safe operation in high-temperature conditions by ensuring thermal endurance. Its operating ambient temperature ranges from - 15 to + 40 degrees Celsius. This motor features continuous duty capabilities to operate continuously without any reduction in performance during extended periods of operation. This DC motor is suitable for conveyor systems and automated machinery.
