<P>PROBLEM TO BE SOLVED: To provide a control method of a rotary electric motor, which reduces the speed variation of a rotor. <P>SOLUTION: The angular speed of the rotor 12 is operated by detecting a position of the rotor 12. Angular acceleration is operated on the basis of the operated angular speed. A prediction time Δt corresponding to a detection prediction time when the rotating position of the rotor 12 is predicted to be detected next is operated from the angular speed, the angular acceleration and a prescribed rotation position interval. Drive command data w stored in a register 6a is converted into a drive command W at a time obtained by subtracting a processing time ΔT of a control device 100 from the detection prediction time of the rotor 12, and the drive command W is outputted to an excitation coil 13a of the rotary electric motor 11. <P>COPYRIGHT: (C)2011,JPO&INPIT |
