High-voltage motors are distinguished by voltage levels. For example, if it is usually 1000V or more, it is considered to be a high voltage motor, and 380V and 660V are low voltage motors. Ordinary motors refer to relatively special motors. Such as dragging the motor of the water pump, fan, compressor, crusher, etc.
A high voltage motor is a motor with a rated voltage of 1000V or more. Commonly used are 6000V and 10000V voltage, due to different foreign power grids, there are also 3300V and 6600V voltage levels. The high-voltage motor is generated because the motor power is proportional to the product of voltage and current. Therefore, the low-voltage motor power is increased to a certain extent (such as 300KW/380V).
The current is limited by the allowable capacity of the wire, or the cost is too high. A high power output needs to be achieved by increasing the voltage. The advantage of the high-voltage motor is that it has high power and strong impact resistance; the disadvantage is that the inertia is large, and it is difficult to start and brake.
