commutation and force generation, the selected servo drive must be
compatible with the LC series phasing; and be wired to the motor correctly.
As shown in the phasing diagram:
S1 in phase with C-A Back EMF
S2 in phase with A-B Back EMF
S3 in phase with B-C Back EMF
Phase sequence = S1 leads S2 leads S3. Spacing is 120 degrees.

Back EMF Voltage vs. Hall Signals
Phasing direction = coil toward motor power cable or magnet assembly away
from power cable as shown in Figure 2.16.
ATTENTION
!
Incorrect Motor/Hall wiring can cause runaway conditions.
