<P>PROBLEM TO BE SOLVED: To provide a brushless motor in which occurrence of unevenness in rotation is suppressed during low speed rotation. <P>SOLUTION: A switch section 10 can make a switch between a first connection state for introducing a central mixing signal from a joint 26 to the minus inputs of comparators 11U, 11V and 11W and a second connection state for introducing signals of U phase, V phase and W phase thereto. The switch section 10 is brought into the first connection state when rotation is started and brought into the second connection state during low speed rotation. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
