<P>PROBLEM TO BE SOLVED: To prevent the occurrence of regeneration abnormality by changing the current limit value of a current limiter 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, and changing the current limit value (Im). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
