| Abstract: | The asynchronous motor has a series of merits such as small volume, light weight, simple structure, convenient maintenance and low production and operating cost. It can be widely used in industry, agriculture and daily life and so on. This design mainly realized the frequency conversion and variable voltage of the three-phase PWM inverter bridge by using the HEF4752 integration chip, therefore realized frequency conversion and velocity modulation of the asynchronous motor. |
