4.4.1 3-Phase AC/BLDC High Voltage Power Stage
Motorola’s embedded motion control series high-voltage (HV) ac power
stage is a 180-watt (one-fourth horsepower), 3-phase power stage that
will operate off of dc input voltages from 140 to 230 volts and ac line
voltages from 100 to 240 volts. In combination with one of the embedded
motion control series control boards 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 a power stage. It
supports a wide variety of algorithms for both ac induction and brushless
dc (BLDC) motors.
Input connections are made via 40-pin ribbon cable connector J14.
Power connections to the motor are made on output connector J13.
Phase A, phase B, and phase C are labeled PH_A, Ph_B, and Ph_C on
the board. Power requirements are met with a single external 140- to
