ABSTRACT:
In a brushless motor having a field permanent-magnet part (10), an altering signal producing circuit (22) produces altering signals which vary analogously with output signals of a position detector (21). Then, a first distributing circuit (31) and a second distributing circuit (32) distributes first and second output current signals of a command block 15 to first and second three-phase distributed current signals which vary analogously with the altering signals. The first and second distributed current signals are composed by a distributing composer (33) to produce three-phase distributed signals. A driving block (14) uses the three-phase distributed signals to produce driving signals for the three-phase coils.
