1, the motor power can be made large, the maximum can reach several thousand, or even tens of thousands of kilowatts. This is because the current of the high voltage motor can be much smaller than the current of the low voltage motor when the same power is output. For example: 500KW, the four-phase three-phase AC motor has a rated current of about 900A at a rated voltage of 380V, and only about 30A at a rated voltage of 10KV. Therefore, the high voltage motor winding can use a smaller wire diameter. As a result, the stator copper loss of the high voltage motor is also smaller than that of the low voltage motor. For a motor with a higher power, when a low-voltage power is used, a larger area of the stator slot is required due to the need for a thicker wire, so that the diameter of the stator core is made large, and the volume of the entire motor becomes large;
2. For larger capacity motors, the power and distribution equipment used in high-voltage motors has less overall investment than low-voltage motors, and the line loss is small, which can save a certain amount of power consumption. In particular, a 10KV high-voltage motor can directly use the grid power supply, so that the investment in the power supply device becomes less, the use becomes simpler, and the failure rate becomes smaller.
1. The cost of the winding is relatively high, and the cost of the related insulation material will also become higher;
2. The requirements for the use environment are far higher；
With competitive price and timely delivery, CHANGLI ELECTRIC MOTOR sincerely hope to be your supplier and partner.
3. The insulation treatment process is difficult, the working time is more, and the motor manufacturing is longer.
