Drive is a high-tech, high value-added , high -tech products in return . The initial drive is not to use energy-saving , but instead of AC Drives DC Drives , and meet the requirements of process control .

With the development of automation, power electronics technology , the drive motor speed control as a key equipment , changing old patterns of ordinary motor can only run at constant speed , so that the motor and drag loads without any change in circumstances that can adjust the speed of the output in accordance with the requirements of the production process , thereby reducing electrical power consumption , achieve the purpose of the system run efficiently .

Currently, the saving rate generally drive about 20 % -30 %, the highest even more than 50% , the working parameters of the inverter energy-saving effect is associated with the application environment . Operating conditions of the motor parameters are reasonable, changes in characteristics of the load carried , and the initial adjustment device , the governor can have a direct impact on the way the inverter energy-saving effect .

With the rapid expansion of inverter technology and product development capabilities , the drive in the cement , elevators , printing, electricity and other modern industry, medicine, communications, transportation , transport, electricity, electronics, environmental protection and other fields as well as the development and application of an unprecedented , almost sectors of the national economy are inextricably linked with the drive . According to 720 yuan / KW price estimate , even without considering the new motor , the market scale of China’s drive has reached 73.1 billion yuan , very broad space for development .
