Continuous load applications: Mainly in areas requiring a certain speed but not high speed accuracy, such as fans, pumps, blowers and other applications, which are low cost and mostly open-loop control.
Variable load applications: Mainly the application that the speed needs to change in a certain range, which has higher demand for motor speed characteristics and dynamic response time characteristics. Such as household appliances, dryers and compressors are good examples. In the field of automotive industry, oil pump control, electrical controller, engine control, etc., the system cost of such applications is relatively higher.
Location application: Most industrial control and automatic control applications belong to this category. Energy transmission is often accomplished in these applications, so there are special requirements for dynamic response of speed and torque, and higher requirements for controller. Photoelectric and some synchronous devices may be used for speed measurement. Many applications, such as process control, mechanical control and transportation control, belong to this category.
In the era of power consumption, the whole world is advocating energy saving and environmental protection. When it comes to energy saving, brushless DC motor embodies a great advantage. Under the same power, it can achieve a great degree of energy saving. Brushless DC motor integrates AC motor and DC motor. It not only has a series of advantages such as simple structure, reliable operation and convenient maintenance of AC motor, but also has the characteristics of high power and good speed regulation function of DC motor. Brushless DC motor and other motors have high reliability, high power and excellent adjustment. There are many advantages such as speed function.
