Product Description:

The Kollmorgen SR3644-334-7-560 is a Permanent Magnet DC Motor designed for industrial automation applications demanding reliable, efficient and consistent operation. This motor features a robust construction to withstand rigorous environments while maintaining optimal functionality.

This SR3644-334-7-560 DC motor delivers a power output of 1 HP with an impressive speed of 1800 RPM. This provides the necessary torque for various mechanical operations. Its intermittent duty cycle ensures the motor can handle short bursts of high power that is suitable for applications where performance and durability are critical. The permanent magnet design of this motor enhances energy efficiency, reduces operational costs while delivering superior torque at low speeds compared to traditional wound field motors. It operates at 90 V D and is crafted with high quality materials. This motor’s housing is built for excellent thermal management that ensures longevity even under demanding conditions. The front mounted shaft of this motor offers versatile installation options that makes it adaptable to a wide range of equipment from conveyor systems and pumps to automated machinery and material handling equipment.

This SR3644-334-7-560 DC motor operates based on the principle of electromagnetic interaction between the magnetic field generated by permanent magnets and the magnetic field produced by the current carrying armature windings. The stator of this motor consists of permanent magnets that create a constant magnetic field while the rotor also known as the armature contains windings connected to a commutator and brushes. The integrated vent slots around the rear cover promote efficient cooling and reduces the risk of overheating during operation. It is compliant with industrial safety and performance standards. This SR series permanent magnet motor represents a perfect blend of durability, efficiency and high output.
