Figure 38 shows a three phase, three step, half wave motor
controller. This configuration is ideally suited for
automotive and other low voltage applications since there is
only one power switch voltage drop in series with a given
stator winding. Current flow is unidirectional or half wave
because only one end of each winding is switched.
Continuous braking with the typical half wave arrangement
presents a motor overheating problem since stator current is
limited only by the winding resistance. This is due to the lack
of upper power switch transistors, as in the full wave circuit,
used to disconnect the windings from the supply voltage
V
M
. A unique solution is to provide braking until the motor
stops and then turn off the bottom drives. This can be
accomplished by using the Fault Output in conjunction with
the Output Enable as an over current timer. Components
R
DLY
and C
DLY
are selected to give the motor sufficient time
to stop before latching the Output Enable and the top drive
AND gates low. When enabling the motor, the brake switch
is closed and the PNP transistor (along with resistors R
1
and
R
DLY
) are used to reset the latch by discharging C
DLY
. The
stator flyback voltage is clamped by a single zener and three
diodes.
