Product Description:

The SR3640-1034-84-7-56HC is one of Kollmorgen Automation popular permanent magnet motor designs. It is built with a formidable housing unit that is suited to the harsh operating conditions of industrial environments. This motor is strong enough to withstand explosions and is suited for Washdown duty. Under ideal operating conditions, this motor will maintain an efficiency level of about 95 per cent. The magnets responsible for the excitation and rotation of the motor rotor are patented anti-cogging magnets that are built for low-speed operation and a high overcurrent capacity. The magnets also support dynamic braking without demagnetization. The permanent magnets of the motor are significantly smaller, lighter and more efficient than those available in other motor designs. There is a fan integrated into the housing of this motor design to get rid of excess heat through a process of forced ventilation.

The SR3640-1034-84-7-56HC motor design features large ball bearings that prevent leakage of lubricating fluid from the motor housing. The commutator in this motor is rugged and fused into the motor, which plays a critical role in helping the motor maintain a low inertial during its operation. There is a conduit box on top of this motor; this box serves as an interface for the power and feedback cable required by this motor during operation.

The SR3640-1034-84-7-56HC does not require an additional control cabinet for installation; it can be directly fitted into industrial environments. There is a blue varnish covering the housing of this motor to protect it from deterioration caused by liquids and other corrosive substances. The input voltage required by this product is about 180 volts, while its input current requirement is about 2.6 amperes. The typical operation speed of the motor is also measured to be about 1750 revolutions per minute.
