Electrical connection
T40FH A4429-1.0 HBM: public 37
S Should differences in potential occur between the
machine rotor and stator because of unchecked leak
age, for example, this can usually be overcome by
connecting the rotor definitively to ground, e.g. with a
wire loop. The stator must be connected to the same
(ground) potential.
6.3 Connector pin assignment Option 4,
Code SU2, DU2, HU2
The stator housing has two 7-pin connectors, an 8-pin
connector and a 16-pin connector.
The supply voltage and shunt signal connections of con
nectors 1 and 3 are each electrically interconnected, but
are protected against compensating currents by diodes.
There is also a self-resetting fuse (multifuse) to protect
the supply voltage connections against overload by the
stator.
