Due to the mechanical arrangement, there is only one 0° position in each segment.
Star motor
7.2.3.7 Star motor
The star motor has a brushless three-phase drive with
integrated measurement system.
The motor shaft has a hollow design. Via this hollow shaft
the compressed air is supplied to the holding circuit of the
20 segments.
The vacuum in the holding circuit is measured via the
connection (4).
The air blast and vacuum in the pickup/placement circuit
are measured via the connection (5).
The star motor is not a spare part.

7.2.5.2 Overview of Vacuum Supply [ ➙ 227]
▪ 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).

Nozzle Changer (optional)
▪ The nozzle changer has 6 magazines, each with 12
nozzle garages for individual configuration.
▪ A maximum of 2 nozzle changers can be installed per
C&P20A head.
(X4I: max. 1 nozzle changer, only 4 magazines at
locations 2/4)
▪ If the nozzle changer is backfitted, the height of the
nozzle changer needs to be checked with a caliper.
▪ Each magazine is recognized via a micro switch and
indicated by a green LED.
