The construction of the reverse rotation detector circuit
is shown in Fig. 17.
Reverse rotation detector
Motor operation during reverse detection
When E
C
< E
CR
, forward rotation (right rotation)
When E
C
> E
CR
, reverse torque is applied to reduce speed (right rotation)
When the motor reverses, the reverse rotation detector operates, and the coil output is opened.
Free rotation in the reverse direction by inertia.

The phase relationship between the hall input sig-
nals H
2
and H
3
is as shown in Fig.18, and the re-
verse rotation detector circuit does not operate.
(
2) Reverse (E
C
> E
CR
)
The phase relationship between H
2
and H
3
is
opposite to that for forward rotation, and the re-
verse rotation detector circuit operates to switch the
output off and leave it in the open state.
