APPLICATIONS:
Figure 9A shows an example of position and/or velocity control
hook-up with inner torque loop using the Digital Signal Processor
(DSP) for motor control. Using software, the DSP can be imple-
mented with one of a range of several motor control algorithms,
such as SVM (Space Vector modulation) or other FO (Field
Oriented) control depending on the specific application.
Figure 9B shows an example of torque control loop with regen-
erative clamp protection using UC-1625, two PW-84075P6 and
one PW-85075P6. Two PW-84075P6 (
bridge with current
sense) sense the current in motor phase A and C.
pins on each of the PW-84075P6 can be tied together to gener-
ate a single composite analog output which is compared to the
torque commanded input to produce an error signal. UC1625
use this error signal to regulate the output current (or torque) by
controlling the duty cycle of the output transistors.
I_ABSVAL
For the case when the resolver/syncho are available instead of
Hall-effect devices, the circuit shown in Figure 9C converts the
resolver (sin and cos) signals to Hall signals which can used to
commutate the output transistors.
