Motor Commutation Phasing (60° standard)
All standard (stock) brushless DC motors and gearmotors manufactured by
Bodine Electric Company are designed for 60° commutation .
The factory
setting for our BLDC speed controls is also for 60° commutation.
It is possible
to configure our BLDC stock controls to operate non-Bodine BLDC motors
and gearmotors with 120° commutation angle .
To change the sensor phasing
output on our stock controls for 120° commutated gearmotors or motors, set
DIP switch number 6 to the “Off”
position . Please note that further application
details must be considered to properly match a non-Bodine BLDC motor with
one of our stock BLDC controls . To avoid damage or system performance
issues, please consult our Technical Support staff at 773-478-3515 or via
E-mail: info@bodine-electric .com .

Commutation Sensor Connections
The commutation sensor leads are prewired in the Model 3983 cable assembly
and terminated in a six-pin connector (Figure 3) . There is a corresponding
“Commutation” connector on the main control board (Figure 4) . Mate the
polarized cable connector to the “Commutation” connector . The connectors
can only mate one way .
