When
currents are
allowed to
flow through only the
coil
03 as
shown
in Fig.
4.2,
the
magnetic fluxes
produced by
the
coil
and
the
permanent magnet
will
flow
through
the poles of the
coil
03, causing the
motor
to
move
the right
and then
stop
in
the position indicated
in Fig. 4.2.
Fig.
4.3
Further,
when
currents
are
let
flow through the
coils
01
and 02
in
the opposite
direction
from the above, the
magnetic
fluxes
produced by
the
coils
and
those
produced by
the
permanent magnet
will
cancel
each other
at
the poles of the
coil
01 because of
their
opposite direction.
The magnetic
fluxes
generated
by
the coils
and
the
permanent magnet
will
go through the poles
of the
coil 02.
Consequently,
the poles of the
coils
02 and 03
will
be
attracted to
the poles of the
rail,
and
the
motor
will
further
move
to the right
before
it
stops at
the point indicated in Fig.
4.3.
Thus, the
motor
is
moved by
successively
changing
the direction of the currents
flowing through the
coils.
