Introduction of high voltage motors

High-voltage motors refer to motors with rated voltages above 1000V. The voltages of 6000V and 10000V are often used. Due to the different power grids in foreign countries, there are also voltage levels of 3300V and 6600V. The high-voltage motor is generated because the motor power is proportional to the product of the voltage and the current. Therefore, when the power of the low-voltage motor increases to a certain extent (such as 300KW/380V), the current is limited by the allowable bearing capacity of the wire, or the cost is too high. It is necessary to achieve high power output by increasing the voltage. The advantage of the high-voltage motor is that it has high power and strong impact ability; the disadvantage is that the inertia is large, and it is difficult to start and brake.
Uses: High-voltage motors can be used to drive a variety of different machinery. Such as compressors, pumps, crushers, cutting machine tools, transportation machinery and other equipment, for mining, machinery industry, petrochemical industry, generators and other industries as prime movers. Motors used to drive blowers, coal mills, rolling mills, and hoists should indicate their use and technical requirements when ordering, and adopt special designs to ensure reliable operation.
