Product Description

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.

Center height range: 315-500mm
Motor power range: 80KW-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.

YR AC slip ring has the advantages of high efficiency, strong overload capability, low noise, low vibration, reliable structure and beautiful appearance. The motor casing is a rigid cast iron casing, and the motor slip ring is located outside the non-bearing end for easy replacement and maintenance.


1. The outer packaging of the products are all standard export-oriented wooden plywood packaging.
2, the product packaging is protected by moisture, water plastic soft packaging
3. For products with special transportation requirements (such as temperature, fragile, variability, and easy to get wet), the packaging protection measures will be strengthened, and the target mark will be printed on the package.
4. There are obvious signs and symbols on the packing box that must be paid attention to during transportation and storage (such as position, moisture, rain, shockproof, lifting position, etc.).


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.
