WebThe asynchronous motor is converted to a model similar to DC motor to control through coordinate transformation, and adopt SPWM inverter circuit, the motor runs with load implements ideal speed and steady operation, providing appropriate speed for aerostatic guide way. Realize simulation of asynchronous motor variable frequency speed regulation … Weband its speed is proportional to the power source frequency f and inversely proportional to the magnetic polar pair number P. Calculated per minute, the speed of the rotating magnetic field n 0 can be represented by this equation: p f n 60 0 = (E-1) Where f is the frequency of power source and P is the magnetic polar pair number. 2.2 VVVF Control
