Bearings
Selecting the bearing
1FW6 torque motors are built-in motors for directly driven rotary or swivel axes. To set up a
complete drive unit, a bearing between the stator and rotor is required in addition to the
phase-angle encoder system.
Your choice of bearing is governed by the following factors:
●
Geometric requirements (internal and external diameter)
●
Speed
●
Load (magnitude, direction)
●
Rigidity (accuracy, pretension)
●
Service life
The bearing is not included in the scope of supply.
WARNING
Bearing currents and static charging of the rotor
Depending on the design and properties of the bearing, the rotor may become statically
charged!
•
Apply the corresponding remedial measures, e.g. insulated bearings or the appropriate
grounding.
Note
Radial forces are generated between the stator and rotor. These must be taken into account
when you select the bearing, see also the Chapter "Forces that occur between the stator and
