<P>PROBLEM TO BE SOLVED: To provide inverter driver and driving method which can drive an inverter circuit such that the rotor of a motor can be brought into preset rotary state correctly through a simple arrangement. <P>SOLUTION: A main controller 4 is provided with first analog rotary information representative of rotary state of the rotor of an induction motor 2 from a resolver 3. The main controller 4 supplies power for driving the induction motor 2 based on an angular speed command value Ω<SB>REF</SB>1. The main controller 4 provides first and second subcontrollers 5 and 6 with second analog sine value data and second analog cosine value data representative of rotary state of the rotor through a first transmission line 8. The first and second subcontrollers 5 and 6 supply power for driving the induction motor 2 in synchronism with the main controller 4 based on the second analog sine value data and second analog cosine value data provided from the main controller 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
