Recently, Laiwu Steel Group Co., Ltd. board Daichang machine shop motor class workers Winder successful implementation of a transformation frequency control to achieve the precise speed regulation winding machine, greatly improving the efficiency of the motor repair. Daily work of the motor class workers winding machine is used by a regulating transformer controlled by adjusting the voltage, the staff have to rely on before each winding voltage regulator to adjust the speed winding machine, low efficiency, and the voltage Adjusting the error is larger, the rate of reduction required to achieve difficult to control. In response, workers decided to ban the motor winding machine control system on conversion technology, with the help of the technical staff, they designed the electrical control schematic diagram, the use of a maximum output of 2.2KW inverter, by change the output adjustment potentiometer to precisely regulate the motor speed, and the addition of a foot switch to control access to the main circuit switching, to achieve real-time control of the motor. After transformation, the winding machine easier to operate, accurate speed adjustment so that the motor efficiency by more than a third repair.
