How is timing measured?
It is meaured by the degrees the brushes have been rotated away from the center position. Most motors come with a lablel that indicates the degrees and calibration marks to show where the timing is set. Eventhough timing refers to the position of the brushes in relation to the magnets, all motors have either a moldeded-in pointer or an endbell screw that measures timing at a “zero point”. This is usually aligned exactly between the two mounting screws on the bottom of the motor can.
