D.8 Multiphase Motor Commutation (COMM)
MC68F375
REFERENCE MANUAL
The COMM function generates the phase commutation signals for a variety of brush-
less motors, including three-phase brushless direct current. It derives the commutation
state directly from the position decoded in FQD, thus eliminating the need for hall ef-
fect sensors.
The state sequence is implemented as a user-configurable state machine, thus pro-
viding a flexible approach with other general applications. A CPU offset parameter is
provided to allow all the switching angles to be advanced or retarded on the fly by the
CPU. This feature is useful for torque maintenance at high speeds.
