Three Phase Closed Loop Controller
The MC33033, by itself, is capable of open loop motor
speed control. For closed loop speed control, the MC33033
requires an input voltage proportional to the motor speed.
Traditionally this has been accomplished by means of a
tachometer to generate the motor speed feedback voltage.
Figure 37 shows an application whereby an MC33039,
powered from the 6.25 V reference (Pin 7) of the MC33033,
is used to generate the required feedback voltage without the
need of a costly tachometer. The same Hall sensor signals
used by the MC33033 for rotor position decoding are
utilized by the MC33039. Every positive or negative going
transition of the Hall sensor signals on any of the sensor lines
causes the MC33039 to produce an output pulse of defined
amplitude and time duration, as determined by the external
resistor R
1
and capacitor C
1
. The resulting output train of
pulses present at Pin 5 of the MC33039 are integrated by the
Error Amplifier of the MC33033 configured as an
integrator, to produce a dc voltage level which is
proportional to the motor speed. This speed proportional
voltage establishes the PWM reference level at Pin 11 of the
MC33033 motor controller and completes or closes the
feedback loop. The MC33033 outputs drive a TMOS power
MOSFET 3phase bridge. High current can be expected
during conditions of startup and when changing direction
of the motor.
The system shown in Figure 37 is designed for a motor
having 120/240 degrees Hall sensor electrical phasing. The
system can easily be modified to accommodate 60/300
degree Hall sensor electrical phasing by removing the
jumper (J
1
) at Pin 18 of the MC33033.
