What are the ways and characteristics of motor energy saving?

 

Electric AC220V 800KG Wholesale Roller Shutter Door Motor With Electric Limit.jpgIndustrial production is inseparable from electric motors. Saving energy in the motor will save a lot of energy. There are two aspects to energy saving of the motor: on the one hand, it reduces the loss of the motor itself, improves the efficiency, and produces an energy-efficient motor. On the other hand, it improves the operating conditions of the motor, and the system maintains the motor load rate and the speed of the motor. In the aspect of higher efficiency, we will improve the overall system operation efficiency.


In terms of improving the efficiency of the motor itself, optimizing the design, reasonably increasing the conductor material, selecting and adding high-performance silicon steel sheets, and improving the efficiency of the asynchronous motor are one of the development directions of motor technology at home and abroad.


The permanent magnet synchronous motor is a permanent magnet synchronous motor with self-starting capability by installing a permanent magnet inside the rotor of the asynchronous motor instead of the magnetic field provided by the exciting current in the stator winding of the asynchronous motor. There is no rotor resistance loss on the rotor during stable operation, which can reduce the total loss by 20% to 30%, thus increasing efficiency by 2 to 4 percentage points. Through reasonable design, the power factor of the motor can be made high, so that the current in the stator winding of the motor can be significantly reduced, and the copper loss of the winding is significantly reduced, thereby improving the efficiency of the motor.
