▪ The star motor is a brushless three-phase drive with
sinus commutation.
▪ An optical measurement system is used for both
commutation and recognition of the rotary angle. This
supplies the track signals A, B and the zero pulse.
▪ The motor is controlled with the help of these track
signals. The actual values of the position are
evaluated on the axis controller. The servo unit
enhances performance and is supplied with 2-phase
current from the axis controller board. (The third
phase is calculated automatically.)
▪ A flange is installed on the motor shaft which is
screwed to the star frame. The smoothed distributor
disc (1) is located between the flange and the star
frame.
▪ The motor shaft has a hole for the compressed air
supply, used to feed the holding circuit.
▪ The smoothed distributor disc enables vacuum and
air blast to be measured in the hold circuit (3) and
placement/pickup circuit (2).
