High efficiency and energy-saving motor adopts new materials, new processes and optimized design to reduce the consumption of mechanical energy, electromagnetic energy and thermal energy to achieve the purpose of improving output efficiency. Compared with the ordinary motor, the high-efficiency energy-saving motor can improve the efficiency by about 4%. Although this kind of new motor has been on the market for a long time in our country, but the demand for it is relatively small in our country. Now the utilization rate of high-efficiency and energy-saving motor in our country is only below 20%. It can be seen that it is very important and necessary to strengthen people's understanding of high-efficiency and energy-saving motor. The application of high-efficiency and energy-saving motor in power plant can significantly reduce the power consumption of power plant and improve the power efficiency.

1 overview of high efficiency and energy saving motors

1.1 operation principle of high efficiency and energy saving motor

In the same time, the total energy consumption of high-efficiency and energy-saving motors can be reduced by about 20% compared with ordinary motors, and the energy saved is about 15%. The motor mainly consumes copper and iron in operation, but the high-efficiency and energy-saving motor uses new ferromagnetic materials to replace the common iron core in the selection of manufacturing materials, and at the same time selects special offline tools to improve the full rate of stator slot, so as to increase the cross-section area of copper wire, which can not only effectively reduce the loss of iron and copper, but also significantly increase the manufacturing accuracy of the motor The stray power consumption is greatly reduced. In addition, the manufacturing process and technology of high-efficiency and energy-saving motor are all modern technologies, among which the high-quality electrical silicon steel sheet with high magnetic conductivity and low loss is mainly selected to make its rotor core and stator core, so that the loss of high-efficiency and energy-saving motor in the operation process is small, the power factor is high, the use time is long and the stability is high, and the new materials And the process manufacturing also reduces the area and volume of the efficient energy-saving motor.
