<P>PROBLEM TO BE SOLVED: To provide a controller of a brushless motor simplified in constitution for inputting a lead angle setting signal and reducible in cost. <P>SOLUTION: The controller 30 of the brushless motor 20 comprises: sensor output signal input terminals 31u, 31v and 31w that input sensor output signals; a motor control circuit 30c that generates an energization signal for rotatively driving the brushless motor 20; and a lead angle adjustment information storing memory 30d that stores lead angle adjustment information. The controller of the brushless motor is also constituted such that the motor control circuit 30c adjusts a lead angle in the energization signal on the basis of the lead angle adjustment information stored in the lead angle adjustment storing memory 30d. Information expressed by the combination of each signal in the sensor output signals Hu, Hv and Hw inputted via the sensor output signal input terminals 31u, 31v and 31w is stored in the lead angle adjustment information storing memory 30d of the controller 30 as the lead angle adjustment information. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
