Three Phase Closed Loop Controller
The MC33035, by itself, is only capable of open loop
motor speed control. For closed loop motor speed control,
the MC33035 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 39 shows an application whereby an
MC33039, powered from the 6.25 V reference (Pin 8) of the
MC33035, is used to generate the required feedback voltage
without the need of a costly tachometer. The same Hall
sensor signals used by the MC33035 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 output train
of pulses at Pin 5 of the MC33039 are integrated by the error
amplifier of the MC33035 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 13 of the MC33035 motor
controller and closes the feedback loop. The MC33035
outputs drive a TMOS power MOSFET 3phase bridge.
High currents can be expected during conditions of startup,
breaking, and change of direction of the motor.
The system shown in Figure 39 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
2
) at Pin 22 of the MC33035.
