Product Description

YR series heavy-duty high-voltage slip ring motor (open type) is a steel plate welding machine base, horizontal structure large-winding three-phase asynchronous motor. The modified model has the advantages of high efficiency, strong overload capability, low noise, small vibration, reliable structure and beautiful appearance, and is suitable for supporting imported equipment.
YR series heavy duty high voltage slip ring motors (open type) are manufactured in accordance with IEC standards. This series of motors is an upgraded product of JR series large-scale wound rotor motor. It uses advanced production technology and has been carefully designed to make the main performance indexes of this series of motors excellent. YR series large slip ring motor can be used as the prime mover of rolling mill, hoist, water pump, compressor, ball mill and other mechanical equipment. It is suitable for places with small capacity or large starting torque to improve starting performance.
YR series heavy duty high voltage slip ring motor (open type) adopts Class F insulation grade. The rotor coil is made of copper strips wrapped with Class F insulation material, and the welding between the coils and between the coil and the conductive row is made of silver brazing to ensure the reliability of the motor operation.
YR series large high voltage slip ring motor (open type) is generally made of single shaft extension, which can be made into double shaft extension according to user needs. The direction of motor rotation can be arbitrarily selected, but it cannot be reciprocated or reversely braked.

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.).


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. We adhere to the service tenet of "focus on products, service with heart" and provide high-quality motor products to customers.
