Checking The Work Performed - Siemens SIMOTICS T-1FW6 Operating Instructions Manual

Installation
5.5 Checking the work performed
Procedure
1. Prepare the mounting surfaces of the components to be installed and the machine as follows:
– Deburr and round off any drill holes (e.g. cooling inlet/outlet drill holes) inside the
– Carefully remove machining debris, e.g. metal chips, dirt and foreign particles.
2. Insulate the open power connections.
3. Centering and joining the stator and rotor:
Screw the flange face of the stator onto the machine housing and the flange face of the rotor
onto the moving axis. While doing this, observe the following points:
– Use the supplied spacer film to protect the stator and rotor.
– Comply with the specified torques and the specifications regarding the mounting system
4. Remove the spacer film. When the stator and rotor are correctly centered, the spacer film can
be easily removed by hand.
Keep the spacer foil. You may need the spacer film for subsequent transport, packaging and
storage of the motor.
5. Check that the rotor can rotate freely. Ensure that the spacer film and any other foreign bodies
are completely removed from the air gap.
6. Connect the coolant pipes.
7. Connect the power and signal cables.

Checking the work performed

Checking the mounting work
After installation has been completed, check that the rotor can freely rotate. Note that with
short-circuited motor phases, the rotor is difficult to turn - even if no mechanical resistance is
otherwise present.
Before moving the rotor, remove all tools and objects from the area of the rotor and air gap.
Risk of electric shock
A voltage is induced in the stator when the rotor rotates. You can get an electric shock when
touching the terminals, the open cable ends or the plug connector contacts.
• Correctly connect the motor power cables.

WARNING
Alternatively:
Insulate the plug connector contacts or terminals and conductors of open cable ends before
you rotate the rotor.
