Product Description

YR series heavy-duty high-voltage slip ring motor (open type) is a wound rotor three-phase asynchronous motor. This type of motor complies with international ISO standards. The motor cooling method is IC01, and the motor is installed in IMB3 (horizontal with foot). The rated frequency is 50HZ and the rated voltage is 6KV, 10KV.
YR series heavy-duty 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 base with protection class IP00. It is compact in structure and self-recognized for ventilation and cooling. It is designed to be IP44 pipeline ventilation according to user needs.
YR series heavy-duty high-voltage slip ring motor (open type) stator windings are drawn down by 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.
YR series heavy-duty high-voltage 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 grinding machines and lifting machines. , winch rolling mill, crusher, fan, pump and other machinery.

Main process flow of the motor
Motor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint drying
Electronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balance
Motor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storage
