Compared with asynchronous motors, permanent magnet synchronous motors have obvious advantages. It has high efficiency, high power factor, good performance indicators, small size, light weight, low temperature rise, significant energy saving effect, and better quality factor of the power grid, give full play to the capacity of the existing power grid, save the investment of the power grid, it greatly solves the phenomenon of “High-power motor to drag light loads” in electrical equipment.
In addition to the timing protection of the motor, the motor and related mechanical equipment must be overhauled in a planned way.
A permanent magnet synchronous motor has a high power factor, independent of the number of poles of the motor.
Adopts IE5 ultra-high energy efficiency permanent magnet variable frequency motor, and permanent magnets are used to provide excitation without excitation current and excitation loss, which provides the efficiency and power density of the motor.
The inverted umbrella aerator directly driven by the permanent magnet motor has incomparable advantages in the application of sewage treatment engineering.
The frequency converter screw air compressor adopts the stepless variable speed characteristic of the frequency converter and realizes a smooth start through the internal controller or PID regulator.
