Because synchronous motors can operate at advanced power factors by adjusting the excitation current, it is beneficial to improve the power factor of the power grid. Therefore, large equipment, such as large blowers, water pumps, ball mills, compressors, rolling mills, etc., are often driven by synchronous motors.
The electric current For ball mill, enlarging the current is to increase the rotate speed. If the has high rotate speed, its work efficiency will be high. However, there is one notice: the increased current should be within the scope of the rated power range. Otherwise, it will burn away ball mill. 2.
