Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a self-speed regulating motor. Background Art

[0002] A speed-controlled motor is one that achieves higher performance by varying its speed through changes in the number of magnetic pole pairs, voltage, current, and frequency. Due to their superior performance, speed-controlled motors are widely used in industries such as steel, power plants, cables, chemicals, petroleum, cement, textiles, printing and dyeing, papermaking, and machinery for stepless speed regulation of loads with constant or decreasing torque. They are particularly suitable for driving loads such as pumps and fans with large flow rates, achieving excellent energy-saving effects.
