WARNING
Risk of electric shock
Every movement of the rotor relative to the stator and vice versa induces a voltage at the stator
power connections. There is a risk of electric shock if you touch the power connections.
Furthermore, in case of a phase short-circuit, short-circuit braking torques which prevent free
rotation of the rotor can be generated.
• Insulate the open power connections properly.
WARNING
Danger of crushing
If you join the stator and rotor as individual components manually, there is a risk of crushing.
• Use a special joining device for centering and installing. Follow the description of the joining
xture.
Procedure
1. Prepare the mounting surfaces of the components to be mounted and the machine as
follows:
– Carefully remove machining debris, e.g. metal chips, dirt and foreign particles.
– This point only applies to motors with cooling jacket, frame sizes 1FW6090, 1FW6130 and
1FW6150:
Deburr and round o any interior drill holes (e.g. drill holes for coolant inlet and outlet)
of the machine housing.
2. This point only applies to motors with cooling jacket, frame sizes 1FW6090, 1FW6130 and
1FW6150:
Guide both O‑rings over the cooling jacket surface of the motor into the grooves provided.
– Do not overstretch the O‑rings. Do not stretch the O‑rings more than 10%.
– Lightly lubricate the O‑rings. Pull the O‑rings through an oil-soaked rag, for example. Take
into account compatibility with the O-ring material (Viton uoroelastomer).
– Do not twist the O‑rings.
– Do not use any sharp objects!
3. Insulate uncovered power connections.
