Abstract: Permanent magnet coupling speed regulation motor has poor speed regulation performance at low speed. This paper analyzes the structure of the permanent-magnet-coupled speed-regulating motor and its speed-adjusting working principle, and designs a multi-mode speed-adjusting control strategy that selects appropriate control parameters according to the speed conditions to improve the speed-adjusting performance in a wide range. A speed regulation test system for a 5.5 kW permanent-magnet-coupled speed-regulating motor was built. The test results show that the multi-mode speed control strategy can select appropriate control parameters according to the output speed, and quickly and accurately track a wide range of given speeds with strong robustness.
Key words: permanent magnet coupling speed regulation motor; multi-mode; speed control
