brushless motor controller speed advantage in the application of automation equipment, the load of the speed regulation is a common topic. The traditional application, for speed regulation requiring high precision, usually choose ac servo motor controller to achieve. In some low speed, the use of stepping motor controller's speed is also a good option. However, along with the development of the technology of brushless dc brushless motor controller control has become an alternative servo motor controller and speed control of step motor controller trend, the main reason as follows 1, brushless dc motor controller, although there is no encoder, only three hall as a feedback, but with the development of FOC control technology, brushless dc motor controller in the load cases, already can reach the speed rate of change of less than 0. The level of 5%, on the precision of speed regulation, is close to the level of the servo motor controller; 2, brushless dc motor controller + brushless dc motor controller drives the formation of the governing unit, on cost is only about half of the servo motor controller, have the price advantage of natural; 3, with the development of control technology, the speed control system of brushless motor controller, joined more than the servo motor controller, the control function of the make customers more technical support in the application, and lower cost; 4, compared with traditional ac frequency control of motor speed, speed brushless motor controller of high precision, small unit volume, control mode, there are analog, frequency control of motor speed, the pulse width control, bus control and so on a variety of ways, at the same time, speed ratio range is much higher than the combination of ac motor controller and frequency converter, but current brushless speed were limited to the scope of small power, the main reason is the production of brushless dc motor controller is given priority to with small power, more than a few thousand W brushless dc motor controller is very big. At least the current domestic situation. http://www。 tcmotor。 Com/foshan electrical and mechanical equipment co. , LTD. , brushless motor controller, brushless dc motor controller, dc servo motor controller, planetary reducer, brushless drive, electrical and mechanical, foshan electrical and mechanical equipment co. , LTD
