Construction principle of variable frequency motor

Construction principle of variable frequency motor

The speed control and control of the motor is one of the basic technologies of various types of machinery and office and industrial and electrical equipment in industry and agriculture. With the amazing development of power electronics technology and microelectronic technology, the AC speed regulation mode of “special frequency induction induction motor + frequency converter” is leading a new place in the field of speed regulation with its excellent performance and economy. The change of the speed control method is changed. It brings the gospel to all walks of life: to greatly improve the degree of mechanical automation and production efficiency, save energy, improve product qualification rate and product quality, correspondingly improve power system capacity, miniaturize equipment, and increase comfort. The fast speed replaces the traditional mechanical speed regulation and DC speed regulation scheme.
Due to the special nature of the variable frequency power supply and the system's demand for high speed or low speed operation and dynamic speed response, the demanding motor is a demanding requirement, which brings new problems in the electromagnetic, structural and insulation aspects of the motor. .
