Product Description

The YR3 series (IP54) slip ring motor is a closed-wound rotor three-phase asynchronous motor, which is a new generation of design. Its power rating and mounting dimensions are in accordance with IEC national standards.
YR3 series (IP54) winding motor can change the external resistance of the rotor to obtain good starting performance (providing large starting torque under small starting current) and small range speed regulation. It is widely used in mining torque equipment that requires more starting torque than squirrel cage rotor motor; it is also suitable for grid capacity not enough to start squirrel cage rotor motor, frequent starting and long starting time, and simultaneous transmission of synchronous electric shaft Such occasions. Such as: metal cutting machine, crusher, ball mill, rubber and plastic machine (internal mixer, open mill), compressor, sugar mill, rolling mill, wire drawing machine, winch, conveyor belt and other mechanical equipment that requires heavy load starting.
YR3 series (IP54) winding slip ring motor has the advantages of high efficiency, high overload capacity, low noise, low vibration, reliable structure and beautiful appearance. Can be interchanged with imported equipment.
