Abstract
A motor that randomly rotates due to external disturbing source is controlled by supplying a 180 degree energizing means to simultaneously realize low cost, space conservation, low vibration and high efficiency across the board. Resultant current information having 3 phases (U, V, W) flowing through an inverter circuit constituted by a plurality of switch components is detected by a parallel impedance for the purpose of overcurrent detection to reproduce the output current of the inverter that is synchronous with a PWM signal, so as to drive the 180 degree sinusoidal power control realized at the magnetic pole position of the rotor where is regularly estimated. On the other hand, before starting in the occasion of idling rotor caused by external disturbing source (e.g. wind), the sensing voltage generated from the rotation of the motor is used to directly detect the position of magnetic pole, rotation speed and rotation direction of the rotor. Then the rotor can be started.
