High Voltage Electric Motor and low-voltage motor compared to the following advantages:
1, the motor power can be bigger, the maximum can reach thousands, or even tens of thousands of kilowatts. This is because, when the same power output, the High Voltage Electric Motor current can be much lower than the low-voltage motor current. For example: 500KW, 4 of the three-phase AC motor rated voltage of 380V when the rated current of 900A or so, and the rated voltage of 10KV when only about 30A. So the high field motor windings can use smaller diameter. As a result, High Voltage Electric Motor stator copper loss will be smaller than the low-pressure click. For larger power motors, the use of low voltage, the need for thicker wire and the need for a larger area of the stator slot, so that the stator core diameter to do a large, the entire motor volume will become very large;
2, for larger capacity of the motor, High Voltage Electric Motor used by the power supply and distribution equipment than the overall investment in low-voltage motor less, and the line loss is small, you can save a certain amount of power consumption. Especially 10KV High Voltage Electric Motor, you can directly use the power grid, so the investment in the power supply equipment will become less, the use becomes easy, the failure rate will become smaller.
The High Voltage Electric Motor and low-voltage motor compared to its shortcomings are:
1, the cost of the winding is relatively high, the associated cost of insulating materials will be higher;
2, the requirements of the use of the environment is much lower than the low-voltage motor requirements of the environment;
3, the insulation treatment process is more difficult, working hours more cost, longer motor manufacturing cycle.
