Abstract:
A triangle wave generator (4) measures the phase difference between a triangle wave (CA) and the rotor electrical angle (θm) during a first cycle in which the rotation rate of a rotor (7) is detected, and changes the frequency of the triangle wave (CA) when the value of the phase difference between the triangle wave (CA) and the rotor electrical angle (θm) exceeds a threshold value, thereby allowing rapid response to changes in rotor rotation when PWM control is performed.
