4.3.1 MC68HC908MR32 Control Board
Motorola’s embedded motion control series MR32 motor control board is
designed to provide control signals for 3-phase ac induction, 3-phase
brushless dc (BLDC), and 3-phase switched reluctance (SR) motors. In
combination with one of the embedded motion control series power
stages, and an optoisolation board, it provides a software development
platform that allows algorithms to be written and tested without the need
to design and build hardware. With software supplied on the CD-ROM,
the control board supports a wide variety of algorithms for ac induction,
SR, and BLDC motors. User control inputs are accepted from
START/STOP, FWD/REV switches, and a SPEED potentiometer
located on the control board. Alternately, motor commands can be
entered via a PC and transmitted over a serial cable to DB-9 connector.
Output connections and power stage feedback signals are grouped
together on 40-pin ribbon cable connector. Motor feedback signals can
be connected to Hall sensor/encoder connector. Power is supplied
