Star Motor
The star motor has a brushless three-phase drive
with integrated measurement system.
The motor shaft has a hollow design. This enables
compressed air to be supplied to the holding circuit of
the 20 segments.
Vacuum in the holding circuit is measured via the con-
nection
(4).
Air kiss and vacuum in the pickup/placement circuit is
measured via the connection
(5).
The star motor is not a spare part.
Star Motor Details
– 3-phase drive (1)
– Incremental measurement system (2)
– Compressed air connection for hold circuit (3)
– Flange on the motor shaft (6).

– The star motor is a brushless three-phase drive with si-
nus commutation.
– An optical measurement system is used for both commu-
tation 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 sig-
nals. The actual values of the position are evaluated on
the axis controller.The servo unit enhances perfor-
mance and is supplied with 2-phase current from the
axis card. (third phase is a calculated value)
– A flange is installed on the motor shaft. This flange is
screwed to the star carrier. The smoothed distributor
disc
(1) is located between the flange and the star hou-
sing.
– The motor shaft has a 6 mm drilled hole through which
compressed air is supplied to the hold circuit. The
smoothed distributor disc enables vacuum and air kiss
to be measured in the hold circuit
(3) and placement/
pickup circuit
(2).

Component Camera (Type 23 digital)
The component camera is fixed to the C&P20 head
with 4 screws and can be replaced during service work.
Five levels are available for illuminating the compo-
nents.
Visual field: 8.2 x 8.2 mm
Resolution: 14.1 µm/pixels
Component spectrum 01005-2220 max. 6x6mm, Bare
Dies, Flip Chip

Nozzle Changer (optional)
The nozzle changer has 6 magazines, each with 12
nozzle garages for individual configuration.
A maximum of 2 nozzle changer charrier can be in-
stalled for each C&P 20 head.
If the nozzle changer is returned, the height of the noz-
zle changer needs to be checked with a calliper.
Each magazine is recognized via a micro switch and in-
dicated by a green LED.
The functions and calibration are identical with that of
nozzle changers for DLM heads.

Venturi Block
The venturi block consists of 20 small venturi nozzles
and is located behind the silencer.
Each venturi nozzle supplies one segment with vacuum
in the hold circuit.
If a segment is in the pickup/placement circuit, the hold
circuit vacuum is increased (for pickup) or eliminated
via air kiss (for placement).
