Product Description

YRT series high voltage slip ring industrial motor is a new product motor based on the original JR winding slip ring motor. The motor installation size and power and voltage level are consistent with the original JR motor, ensuring no difference in customer replacement. The motor complies with the relevant standards of relevant technical conditions.
YRT series high voltage slip ring motor adopts rotor string resistance full voltage start, which has the advantages of small starting current, large starting torque, high efficiency, low noise, low vibration, good ventilation performance, reliable operation and convenient installation and maintenance.
YRT series slip ring motors are widely used in industrial fields, such as mining machinery and equipment ball mills, crushers and so on. Can also drive a variety of different machinery, such as fans, compressors, pumps, cranes, cutting machines, transportation machinery and other industrial production equipment

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.).
