Hall Sensor

The SGM-04A312 does not have any commutation sensors. It will work with a servo drive that supports sinusoidal commutation without hall correction, such as the Copley Accelnet drives.

Encoder

My standard is positive is when the motor, when viewed from the front, is turning clockwise.
