<P>PROBLEM TO BE SOLVED: To prevent the occurrence of regeneration abnormality by changing a current command in case that the DC voltage at regeneration is over a specified threshold. <P>SOLUTION: This control method for a brushless motor is one which avoids the occurrence of regeneration abnormality by performing calculation in a regeneration abnormality avoiding algorithm part (10) when the DC voltage at regeneration is over a specified threshold, thereby making an optimum current command (Im'). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
