JR Slip Ring Motor Exported to Iran

On April 7, 2020, our company delivered 6 sets of winding slip ring asynchronous induction motors dedicated to JR series ball mills according to the time stipulated in the contract. This batch of JR slip ring motors is supported by a manufacturing and ball mill company in Tangshan City, China, which is exported to Iran in the Middle East. Islamic Republic, used for ball mills during mining operations.

JR slip ring motor is a winding type asynchronous motor specially developed and designed for the mill, which complies with the IEC standard. This series of motors have the advantages of simple structure, safe and convenient use, high efficiency and energy saving, and are the best motor products for supporting mills.

The rating of the JR slip ring motor is based on the rating of the continuous operation system (S1). Rated frequency is 50HZ, rated voltage is 220 / 380V, 380V, 3000V, 6000V, can be designed into 3300, 10000v according to user needs.

The protection grade of this series of motors is IP23; the cooling method is IC01; the structure and installation method of the motor is generally IMB3, which can also be designed for vertical installation according to user needs.

JR series slip ring motors can be rated to run under the following environmental conditions:

1. Altitude does not exceed 1000 meters

2. The ambient temperature is -15 ℃, and the maximum temperature varies with the seasons, but it does not exceed 40 ℃.

3. Indoors with clean air and no corrosive gas such as acid and alkali. It is not allowed to work in an environment containing explosive gas or dust

4. The average monthly maximum humidity of the wettest month is 90%, and the average monthly minimum temperature of the month is not higher than + 25 ℃

The ratio of the maximum torque of the JR slip ring motor at the rated voltage to the rated torque is not less than 1.8

The JR series slip ring motor must be connected to the starting rheostat in the rotor circuit before starting. It is not allowed to start the rotor winding short circuit directly.

JR slip ring motor can drive a variety of different machinery, such as fans, compressors, water pumps, crushers, ball mills, cutting machine tools, transportation machinery and other equipment, can be used in coal mines, machinery industry, power plants and various industrial and mining enterprises Used as a prime mover.
