Energy-saving transformation of the motor system: energy-saving transformation of electric motors, new energy-saving motors, remanufacturing of electric motors, high-efficiency and energy-saving motors, and improved energy efficiency of electric motors-Dongguan motor manufacturers use the latest integrated circuit chip control technology to "dynamically track "energy-saving management control system software" and " "Fuzzy control" software is the mainstream. Computer technology and continuously variable speed technology are used as control methods. Dynamically track, detect and feed back the power consumption changes of the motor running, calculate and control the running feedback signal, and replace the motor at any time. Power conditions dynamically adjust the motor running process In order to achieve the best working voltage and current, it can effectively avoid the waste of current due to excessive motor output power.

In the normal operation of the motor system, the output torque of the motor system is accurately matched with the load demand, so that the motor is always in the best state, thus realizing the fully automatic intelligent control of the motor, thereby saving energy to the greatest extent. This technology can be used for energy-saving transformation of motor drive series such as fans, water pumps, air compressors, etc. It is suitable for energy-saving transformation of factories and buildings, involving steel, electric power, chemical, metallurgy, cement and other industries, light industry, medicine, commerce, etc. field. Rebuild the circulating water system, drag the cold water pump one by one and the towing method. With cutting function. Every 8 hours, it can automatically or manually switch to another motor running under the same frequency converter, and automatically adjust the pump speed according to the final temperature; the water pump adopts a one-to-two method for the same start and stop, and automatic closed-loop adjustment according to the pipe network temperature , With high limit protection function to ensure that the cooling tower does not exceed the maximum capacity; the cooling fan uses one or two methods to achieve closed-loop control according to the radiator water temperature. And set the time period to automatically switch operations within the three time periods. According to the automatic closed-loop adjustment of the pipe network temperature, it has a high limit protection function to ensure that the cooling tower does not exceed the maximum capacity; the cooling fan adopts one or two methods to achieve closed-loop control according to the radiator water temperature. And set the time period to automatically switch operations within the three time periods. According to the automatic closed-loop adjustment of the pipe network temperature, it has an upper limit protection function to ensure that the cooling tower does not exceed the maximum capacity; the cooling fan adopts one or two methods to achieve closed-loop control according to the radiator water temperature. And set the time period to automatically switch operations within the three time periods.

Generally speaking, the system adopts the optimal control principle, fuzzy control, computer closed loop automatic control and other technologies, and the energy saving rate reaches 45%. Purify the dust removal fan system and use a single inverter to drive three motors. During the inspection process or when the motor or inverter fails, the high-speed switchgear switchgear will be manually switched to one or two motors at the power frequency to meet the requirements of the production purification dust purification system. The frequency control method adopts the inverter main control and on-site remote control. This field has closed state, frequency setting and display and trip functions. The system uses 32-bit high-speed DSP chip precision algorithm and PLC control technology. The controller structure adopts a box structure. Each control unit board uses large integrated circuits such as FPGA and CPLD and surface welding technology, and uses industrial communication protocols and optical fibers. The communication makes the system extremely reliable and the energy saving rate reaches 69%.
