Brushless motors are commutated electronically by the controller. The use of Hall effect devices for
commutation is recommended.
The controller requires that the Back-EMF of each motor phase be aligned with the corresponding Hall-
effect signal. To ensure proper alignment, motor, Hall, and encoder connections should be verified using
one of the following methods:
powered
, through the use of a test program; or
unpowered
using an
oscilloscope. Both methods will identify the A, B, and C Hall/motor lead sets and indicate the correct
connections to the controller. Refer to
for powered motor phasing or
for unpowered motor and feedback phasing.
For Aerotech-supplied systems, the motor, encoder and Hall sensors are correctly configured and
connection adjustments are not necessary.
A motor filter module can be installed between the drive and the motor to reduce the effects on
PWM generated noise currents.
