Electrification.Information Age，In performance.Reliability and capacity，Higher requirements for motor。AC frequency conversion speed system and frequency conversion motor.High-power brushless DC motor.Permanent magnet synchronous brushless motor has been greatly developed。
Simultaneously，With the development of emerging industries，The micro motor has also become a highlight of the development of the motor industry.，my country Electrotechnical Electrical Industry(Motor)Development of key products。Rare earth permanent magnet motor，Non-adheric motor is also a new movement of motor technology development。
Adapt to this，Motor drag also has new development，Higher requirements for the drag system，As requested to improve the accuracy and speed of work，Quick start.Brake and reverse，Implement a wide range of speed regulation and automation of the entire production process, etc.，This requires a complete set of automatic control equipment to form an automated power drag system.。And these high-demand drag systems have evolved with automatic control theory，Semiconductor devices and power electronics，And the development and adoption of numerical control technology and computer technology，Continuous improvement and improvement。
In summary，Electricity drag technology development，It has many advantages 巴慕达手冲壶维修网点 that many other drag modes cannot match。It starts.brake.Simple control of inversion and speed control.Convenience.Quick and high efficiency；Motor type，And have a variety of different operating characteristics to meet various types of production machinery requirements；The detection of each parameter of the entire system and the transmission of signals are convenient，Easy to achieve optimal control。therefore，Electricity drag has become the foundation of national economic electrical automation。
