A method of starting an electric brushless rotating machine is provided where a large startup torque is obtained with no use of any rotor position detecting device and the forced commutation can be switched to normal energization easily and smoothly. At the startup stage, any two of three-phase stator windings are energized for initial magnetization (Steps S1 and S2) to hold the magnetic rotor at a position.
