Motor energy-saving measures 7

Motor energy-saving measures 7 1, the new purchase of electric motors, should first consider the selection of high-efficiency energy-saving brands, and then consider other performance indicators as needed to facilitate the conservation of energy. 2. Improve the efficiency of the motor itself. If the self-cooling fan of the motor is changed to its cooling fan, when the load is small or the outdoor motor is in the winter, the cooling fan is deactivated, which is beneficial for reducing the energy consumption. 3. The stator windings are changed into "quantity-triangle" mixed series windings. According to the load, the star connection method or the delta connection method can be used to improve the winding current so as to achieve the purpose of high efficiency and energy saving. 4, using other continuous speed mode of operation. The use of regulator governor, pole-changing motor, electromagnetic coupling governor, frequency converter and other devices. 5, replace the "big horse car" motor, it is a waste of energy, but also easy to cause equipment damage. In addition, a reasonable adjustment of the motor supporting the use of the motor can run in a high-efficiency work area, to achieve energy-saving purposes. 6, reasonable installation of parallel low-voltage capacitors for reactive compensation, can increase power factor, reduce reactive power losses, save energy. 7. The cross-section of the conductor from the power source to the power meter and the motor should meet the requirement of shortening the number, reducing the resistance of the wire and reducing the loss. The above measures can be adopted separately. Can also be used with more than one.
