Permanent magnet variable frequency vacuum pump ‌ is a kind of vacuum pump that uses permanent magnet synchronous motor as the driving motor. Its working principle is through the permanent magnet material manufactured by special materials and electronic control technology, so that the speed of the permanent magnet synchronous motor can be adjusted at any time, so as to achieve the frequency control of the vacuum pump. This technology can make the pump motor speed adjustment to the best state, and thus achieve high efficiency, low noise, low energy consumption ‌.

The core of permanent magnet variable frequency vacuum pump lies in its permanent magnet synchronous motor. This motor has the characteristics of high efficiency, high torque, high power factor and fast response, which can effectively reduce energy consumption and improve efficiency. Through electronic control technology, the speed of the motor can be adjusted at any time, so as to achieve frequency conversion control, and further optimize energy consumption and efficiency .

Our products are widely used in petrochemical, paper, power, semiconductor, food, steel smelting and other industries.
