If you are planning different cable outlet directions or offsets for the primary section position
or the secondary section track, request support from Siemens
(motorsupport.motioncontrol@siemens.com).

Design of the mounting plate
It is your responsibility to manufacture the mounting plate for the application-specific
secondary section track. Obtain advice on this from the your local Siemens office.
The mounting plate must be rigid enough to transmit the motor forces during operation.
The mounting plate must be rigid enough to transmit the motor forces during operation.
For the magnetic return path in version (B), a support plate is required that is at least 8 mm
thick.
In a double-sided arrangement, the forces of attraction theoretically cancel each other out.
However, there is usually some asymmetry in the air gap. This means that approx. 25% of
the attraction force of a motor remain exerted on the support plate. The support plate must
not sag as a result.
Double-sided motors are mainly configured in the normal way. Only difference: In this case,
the dynamic mass is the mass of the secondary section system. This means that the
following must be taken into consideration:
● The mass of the secondary sections or the mass of the magnetic material
● The mass of the (special) secondary section covers
● The mass of the mount of the support plate
● The mass of the guide elements
● The mass of the length measuring system
