High-voltage motors can be made with a large power, with a maximum of several thousand or even tens of thousands of kilowatts. This is because, at the same output power, the current of a high-voltage motor can be much smaller than that of a low-voltage motor. At the same power, the current and voltage are negatively correlated. Therefore, high-voltage motor windings can be used with smaller wire diameters. Therefore, the stator copper loss of the high-voltage motor will also be less than that of the low-voltage motor. For motors with higher power, when low voltage electricity is used, a large area of stator slot is required due to thicker wires, so that the diameter of the stator core is large and the entire volume of the motor will be large. For motors with larger capacity, the power supply and distribution equipment used by high-voltage motors have less investment than the overall investment of low-voltage motors, and the line loss is small, which can save a certain amount of power consumption. Especially for 10kV high-voltage motors, network power can be used directly, which will make less investment in power supply equipment, easier to use, and less failure rate.
