The application of brushless dc motor controller
the application of brushless dc motor controller with the continuous development of brushless dc motor controller, and expand the application field, brushless dc motor controller has been widely used in many industries, such as cars, tools, industrial control, automation and aerospace and so on. In general, the brushless dc motor controller can be divided into the following three main purposes: ( 1) Continuous load application ( 2) The variable load application ( 3) Positioning application 1, continuous load using the application of brushless dc motor controller is mainly used for those who need a certain speed but for speed accuracy is not high, such as fan, water pump, blow such kind of applications. Usually this kind of application cost is lower and is open loop control. 2, application of this kind of variable load mainly refers to the brushless dc motor speed controller need to change within a certain range of the application of brushless dc motor controller, in this type of application of the main controller of brushless dc motor of high speed characteristic and the dynamic response characteristics have higher requirements. In the home appliances washing machine, dryer and compressor is a very good example. In the field of auto industry, oil pump, electric controller, engine control and electronic tool and so on are also a good example. In the field of aviation also has a lot of applications, such as centrifuge, pump, mechanical arm, gyroscope, etc. Using brushless dc motor controller in the field of feedback device of half open loop and closed loop control. This requires complex control algorithm, increased the complexity of the controller has increased the system cost. 3, positioning used most of the industrial control and automatic control applications fall into this category. In the application of the brushless dc motor controller tends to complete energy transmission, such as gear or conveyor belt, so the system controller of brushless dc motor torque and speed of dynamic response have special requirements, at the same time, these applications also may need to change at any time of the brushless dc motor controller, dc brushless motor controller can work in uniform, accelerate, reduce phase, and is likely to load in these stages is changing, so this puts forward higher requirements on the controller, usually this kind of control using closed loop control, even the torque loop, speed loop and position loop three control loop. Speed may be used when the photoelectric encoder and some synchronous equipment. Sometimes these sensors can be used to measure the relative position, is also sometimes used to measure absolute position. Process control, mechanical control and transport control many belong to this type of application. All three of these major application of brushless dc motor controller, than this can be included on the application range of the brushless dc motor controller, of course, with the continuous development of brushless dc motor controller technology, more and more applications are developed gradually.
