Every industry today in promoting energy conservation and environmental protection, energy-saving renovation of brushless dc motor, many companies are already coming in, so, what is the energy saving renovation of brushless dc motor is first, brushless dc motor energy saving reconstruction technique is to replace the traditional brushless dc motor with brushless dc servo motor. Servo motor is a kind of very high precision, smart motor response speed is very fast, but the cost is high, the energy consumption. The brushless dc motor adopts closed loop system, it has the function of the servo motor, brushless dc motor and motor drive integrated into an organic whole, fundamentally change the brushless dc motor and the existing insufficiency, also narrowed the installation space, relative to the servo motor to reduce the cost a lot, because in the process of transforming adopted the most advanced technology, before is better than the traditional motor energy consumption is less. Can be seen in the test of power consumption, brushless dc motor energy saving after modification, the average energy saving rate is above 50%, the highest to 91. 7%, and after the transformation, but also improve the precision of the mechanical equipment, the noise of the machine operation process of noise and temperature, improve the service life of the machine. the second, the different mechanical equipment manufacturers, are trying to find a way to more efficient and energy saving, previous transformation way though to a certain extent, energy saving, but there are other disadvantages, brushless dc motor energy conservation transformation to industrial control automation industry has brought new impetus.
