<P>PROBLEM TO BE SOLVED: To provide a more practical permanent magnet drive system by controlling the magnet flux of the permanent magnet of a variable magnetic flux motor. <P>SOLUTION: In the permanent magnet drive system, the magnetic flux of the permanent magnet of a variable magnetic flux motor 4 is varied to drive control the variable magnetic flux motor 4, by controlling an inverter 5, while varying motor current so as to suppress torque variation based on the magnetic flux command ϕ* processed by a magnetic flux command processor 12. <P>COPYRIGHT: (C)2009,JPO&INPIT |
