The device supporting the moving armature
should be secured centrally so as to respecter
the nominal airgap.
On VAR11, the hub / moving armature assembly
(332) is supplied reamed to tolerance H7 or H8
and splined to tol erance P9.
When assembling or dismantling the moving
armature, never hit or pull it, this action
could generate permanent distortion of the
membrane-spring and malfunction.
In the case where two co-axial shafts are
fitted, the recommended setover is 0,05 mm
maximum. The angular misalignment should
not be greater than 0,1 mm over a length of
100 mm.
It is essential when assembling to respect the
nom- inal airgap (see chapter 1).
3.3.3 PBM VAR00, VAR01 and VAR02
The inductor (104) should be rigidly fixed to
the frame of the machine, centred by the collar
(see figure 5) or directly centred on a bearing
forming a support (see figure 6). In this case, a
circlip fitted in the groove provided for the pur-
pose holds it central to the bearing.

In the case of collar centring, we specify an H9
tolerance.
The setover between the housing and shaft
should not exceed 0,2 mm.
On VAR00, the armature is fixed by means of
CHC “pro file head” screws (DIN 7984) locked
by means of a LOC TITE 270 type thermoplastic
liquid.
On VAR01 and VAR02 the armature is mounted
on a hub (332) or (333), supplied reamed to
tolerance H7 or H8 and splined to tolerance P9.
The assembled hub / armature assembly should
be secured centrally so as to respect the nominal
airgap.
The angular misalignment of the shaft should
not be greater than 0,1 mm over a length of 100
mm.
When assembling or dismantling the moving
armature, never hit or pull it, this action could
generate permanent distortion of the membrane
spring and malfunction.
It is essential when assembling to respect the
nominal airgap (see chapter 1).
