1. Use energy-saving motors and high-efficiency motors to reduce various losses

Compared with ordinary motors, selecting energy-saving motors & high-efficiency motors have simplified the overall design, selected high-quality copper windings and silicon steel sheets, which reduced various losses, reduced losses by 20% to 30%, and increased efficiency by 2% to 7%; The payback period is generally 1 to 2 years or some months. In comparison, the efficiency of high-efficiency motors is 0.413% higher than that of J02 series motors. Therefore, it is imperative to replace the old motor with a high-efficiency motor

2. Select a motor with appropriate motor capacity

Appropriate selection of motor capacity to achieve energy saving ,the following provisions have been made for the three operating areas of three-phase asynchronous motors: load rates between 70% and 100% are economic operating areas; load rates between 40% and 70% are general operating areas; The load rate below 40% is a non-economic operation area. Improper selection of motor capacity will undoubtedly cause a waste of electrical energy. Therefore, using a suitable motor to improve the power factor and load rate can reduce power loss and save electrical energy. ,

3. Use magnetic slot wedges to reduce no-load iron loss

4. Use Y/△ automatic conversion device to solve the phenomenon of power waste

5. The power factor and reactive power compensation of the motor reduces power loss

The power factor and reactive power compensation of the motor improve the power factor and reduce power loss is the main purpose of reactive power compensation. Power factor is equal to the ratio of active power to apparent power. Generally, a low power factor will cause excessive current. For a given load, when the supply voltage is timed, the lower the power factor, the greater the current. Therefore, the power factor should be as high as possible to save energy.

6. Winding motor liquid speed regulation & liquid resistance speed regulation technology help achieve no speed regulation

The technology of winding motor liquid speed control and liquid resistance speed control is developed on the basis of the traditional product liquid resistance starter. The purpose of no speed regulation is still achieved by changing the size of the board spacing to adjust the size of the resistor. This makes it have good starting performance at the same time. It has been energized for a long time, which brings about the heating problem. Due to the special structure and reasonable heat exchange system, its working temperature is limited to a reasonable temperature. The liquid resistance speed control technology for winding motors has been quickly promoted for its reliable work, easy installation, large energy saving, easy maintenance and low investment. For some speed control accuracy requirements, the speed range requirements are not wide,and infrequent speed adjustment of wound-type motors, such as fans, water pumps and other equipment with large and medium-sized wound-type asynchronous motors , using liquid speed control effect is significant.
