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. Center height range: 160-400mm Motor power range: 7.5KW-630KW Rated voltage: 380V/415V/660V/690V Number of poles: 4/6/8/10/12 Rated frequency: 50Hz/60Hz Protection level: IP23 Cooling method: IC01 Working system: S1 Insulation class: B or F Wiring method: stator △ connection method, rotor is Y connection method Installation method: B3 (horizontal installation) Ambient temperature: ≥ -15 ° C and ≤ 40 ° C Remark: When starting this type of motor, the starting varistor must be connected to the rotor circuit of the motor. It is not permissible to short-circuit the rotor windings directly. The large high-voltage wound rotor slip ring motor can increase the large starting torque at a small starting current. The motor is suitable for applications where the capacity of the feeder line is insufficient to start the squirrel-cage rotor, the starting time is long, the starting is frequent, and the small-range speed regulation is required. This series of motors has the advantages of high efficiency, energy saving, low noise, low vibration, light weight, reliable performance, convenient installation and maintenance. The company has large-scale laboratory, intelligent CNC winding machine, CNC rising machine, automatic wrapping machine, VPI high pressure vacuum immersion system, large-scale dipping paint drying furnace, 60 tons test platform, large vertical car, milling machine, grinding machine, Each type of dynamic balancing machine, double-feedback test and detection system with 6MW (12MW) motor and other motor production professional equipment more than 500 sets, sound mechanical equipment processing capacity, to lay a good foundation for customers to improve good quality motor products. There are many types of motor products manufactured and sold by our company. The main products are high- and low-voltage three-phase asynchronous motors. The motor structure types include squirrel-cage type and winding type. Among them, high-voltage synchronous motors mainly support air compressors and mine ball mill equipment. use.
