The Design Of The Motor Controller Module Of Electromagnetic Speed Regulation

speed regulating motor. It can achieve stepless speed regulating smoothly in the broad range. The constitution of the motor is simple, it can run reliable, it is maintained easily, start function is superior, control power is little. It can achieve automatic and remote control easily. Its speed regulating rate is broad, control accuracy is high, save power environmental protection, high efficiency .It is used in various industries broadly. Now, in the industry the motor controllers of Electromagnetic Speed Regulation are made of discrete component mostly. The circuit stability of the device is affected by the parameter and function of the components. The device is composed of many components and its maintenance is difficult, so it need improve immediately.The design develops a controller module with high integration degree to replace the discrete components. The design is composed of fundamental design of the control circuit, analyzing work fundamental, computing parameters, selecting components capacity. After fundamental design, the printing circuit board design consists of placing components, improving and optimizing stability and resistant interference function. The appropriate package design can protect the circuit operate reliably and stably and dismiss heat. Finally the module passed test, which inspects operation of module function and reliability. All parameters reach the design quality, for example control precision and out revolution range. The module operates well and reliably in the practice. Its price is cheap, it made constitution simple.
