Appeal No. 1998-2601
Application 08/809,052
Nth-phase position detection signals outputted from said
position detecting units, so that said first-phase armature
coil may be supplied with power simultaneously with said
second-phase armature coil during a section, said second-phase
armature coil may be supplied with power simultaneously with
said third-phase armature coil during a section, through said
Nth-phase armature coil which may be supplied with power
simultaneously with said first-phase armature coil during a
section,
wherein a first magnetic pole formed in said stator is
magnetized simultaneously with a second magnetic pole adjacent
thereto in a predetermined direction in a manner such that one
is a magnetized North pole while the other is a magnetized
South pole, then, the second magnetic pole is magnetized
simultaneously with a third magnetic pole adjacent thereto in
a predetermined direction in a manner such that one is a
magnetized North pole while the other is a magnetized South
pole, and then, the third magnetic pole adjacent thereto in a
predetermined direction in a manner such that one magnetized
North pole while the other is magnetized South pole up to m x
n magnetic poles, thereby generating a leakage flux passing
through one of two adjacent magnetic poles, of which a
confronting area with a salient pole is smaller, which is
effective for developing a torque between the magnetic poles
and the salient pole, and of which quantity is determined
according to the quality of the magnetic flux passing through
the other of the above adjacent magnetic poles.
