7-30 ELECTRICAL SYSTEM
STEPPING MOTOR OPERATION
Step.1) When current is sent only through circuit
B
, the magnetic force is equilibrated and causes the rotor
to stay at position
b
.
Step.2) When the same amount of current as circuit
B
is sent also through circuit
A
, the rotor turns 15°
counterclockwise by the same amount of magnetic force both from
a
and
b
.
Step.3) When cut off the circuit
B
current and sending the current only through the circuit
A
, the magnetic
force is equilibrated and causes the rotor to turn 30°.
Step.4) When sending the same amount of current both through circuit
A
and
C
, the rotor turns 15° more
to the above.
Thus, the rotor can smoothly turn and stay at any position by electronically controlling the current through the
circuit
A
,
B
and
C
.
