of Mechanical Layout
With the help of a tooth Mechanical Layout rotary movement of the X-axis motor is directly converted
into a lengthwise movement of the placement head, in the X-direction.
The linear guide rails under the X-axis guide the head assembly plate and the placement head along the
X-axis.
The X-motor is cooled by a fan at the Y-axis pickup position and the motor temperature is also monitored
by a sensor.

of Mechanical Layout
A line Mechanical Layout the entire gantry (X-axis, head assembly plate and placement head) in the Y-
axis direction. This linear motor consists of a primary and secondary part. The secondary part consists
of permanent magnets, which are fastened lengthwise (Y direction) to the machine frame.
The primary part consists of inductors (motor windings), which are directly fastened to the gantry, in a
casing.
The drive is cooled by the compressed air supply to the placement head and also has integrated tem-
perature sensors, which are monitored by the axis controller.
