AC Slip Ring Motor

YR series AC slip ring (IP23) motor is a protective wound rotor asynchronous motor. The power level and installation dimensions of the motor are in accordance with IEC standards. The enclosure protection class is IP23, the cooling mode is IC01, and the continuous operation system (S1). Suitable for natural places that are free of flammable, explosive, corrosive gases and relatively clean. 

The YR AC slip ring motor can provide a large starting torque at a small starting current and can adjust the speed within a certain range. It can be widely used in: 
(1) requires a larger starting torque than a squirrel-cage rotor motor; 
(2) The capacity of the feeder line is insufficient to start the squirrel-cage rotor motor; 
(3) Long starting time and frequent starting; 
(4) A small range of speed regulation is required; 
(5) Liancheng "electric shaft" for synchronous transmission, such as: winch, hoist, wire drawing machine, compressor, ball mill, sugar mill, winch, conveyor belt, etc., need heavy load starting, short-time overload operation Equipment.

YR AC slip ring motor is a protective winding rotor asynchronous motor. The power level and installation dimensions of the motor are in accordance with IEC standards. It has the advantages of high efficiency, strong overload capability, low noise, low vibration, reliable structure and beautiful appearance. A large number of mechanical equipment are used together, which can be matched and exchanged with imported equipment. YR slip ring motor is an upgraded product used to replace the old type of wound rotor motor of JR, JR2, JR3, etc. It is an ideal product to achieve energy saving, improve the technical level and operational reliability of the supporting mainframe. The stator of the motor adopts the external press-fit structure, the coil end has reliable support and binding, and the rotor adopts high-strength lacquered flat copper wire. The coil has high mechanical strength, stable and reliable insulation performance, and a separate grounding terminal in the junction box.

YR AC asynchronous slip ring motor adopts Class B or Class F insulation, rated voltage is 380V (also can be made into 660V), rated frequency is 50Hz, stator is △ connection method (Y connection method at 660V), rotor is Y connection method . The structure and installation type of the motor is IMB3 (the base has a foot, the end cover has no flange, and the horizontal type). Stator outlet mode: frame number H160-315 is the side outlet; frame number H355-400 is the ejector line.
