<P>PROBLEM TO BE SOLVED: To provide a brushless motor controller facilitating correction of angle shift with a rotation sensor and reducing noise at the time of motor rotation. <P>SOLUTION: A plurality of lead angle maps different in an advance/delay amount of advance/center/delay are previously stored in a microcomputer 13. A lead angle map setting part 15 selects one of the plurality of the lead angle maps stored in the microcomputer 13 as a control mode of a brushless motor M. The lead angle map with a small driving current value namely, small noise under the same load condition is selected, and the brushless motor M is controlled in accordance with the selected lead angle map. <P>COPYRIGHT: (C)2010,JPO&INPIT |
