The development of frequency conversion speed regulation technology, especially the breakthrough of vector control technology, enables the speed regulation performance of AC electric drive system to be the same as that of DC electric drive system. In terms of output power level and high speed, it has greatly broken through DC motor. Therefore, the AC electric drive system is widely used in rolling mills, mine hoists, paper machines, electric pallet stackers, electric reclaimers and other drives.
In the field of servo drive, the AC servo system with excellent performance is gradually replacing the DC servo system. The AC speed control transmission is rising from the original subordinate position to the dominant position of the speed control transmission.
The development of digital control technology and data communication technology based on microcomputer has made the transition of electric drive from analog control to digital control. The digital control system can use the least amount of hardware standard units and meet various control requirements by compiling different software. The microcomputer has fast computing speed, strong function and large memory capacity, and multiple microcomputers can work together, so it can realize real-time rapid calculation and control, fault self-diagnosis and protection, data communication and processing of the electric reclaimer, and make digitally controlled electrical The overall performance of the drivetrain is significantly improved.
