Product Description

The crane slip ring motor (open type) is a high voltage wound rotor three-phase asynchronous motor. This type of motor complies with the international IEC standard. The motor is cooled by IC01. The motor is installed in IMB3 (horizontal with foot), rated frequency. It is 50HZ and the rated voltage is 6KV, 10KV.
The crane high voltage slip ring motor (open type) is suitable for use in environments where the altitude does not exceed 1000M and the ambient cooling air temperature does not exceed 40 °C. We are also willing to manufacture products for special environments and conditions according to the needs of users.
This series of motors is a steel plate welding machine seat with protection class IP00. It is compact in structure and self-recognized for ventilation and cooling. It is designed to be IP44 pipe ventilation according to user needs.
The stator winding of the heavy-duty high-pressure slip ring motor (open type) of the crane is immersed under VPI vacuum pressure, and the motor has good insulation and moisture resistance. The rotor winding coil is F-class. The bearing is a seat type sliding bearing, the lubrication method is compound lubrication, and the self-lubrication can be adopted in low power and in low temperature environment.
The crane high-pressure slip ring motor (open type) can be equipped with stator winding temperature measuring device and bearing temperature measuring device, which can realize real-time monitoring and alarm of long-distance temperature. This series of motors can be used to drive various mills, hoists and winches. Machines, crushers, fans, pumps and other machinery.

Our company's motor manufacturing factory adheres to the concept of green, efficient and energy-saving production service, pays attention to the harmonious development of internal and external environment, builds environmentally friendly motor manufacturing enterprises, strictly implements motor standard process, and selects high-quality energy-saving materials to ensure the quality of motor products.


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.).
