Mechanical Adjustment Angle And Emf Phase Position - Siemens SIMOTICS T-1FW6 Configuration Manual

Configuration
6.4 Installation
5. This point only applies to motors with cooling jackets, frame sizes 1FW6090, 1FW6130, and
1FW6150:
Position the motor with the free flange surface pointing forward in the machined precisely
dimensioned bore of the machine housing.
O-rings must not be pressed out of the groove or damaged during this step.
Ensure that the motor does not become tilted in the installation space during installation.
Slight tilting of the motor can be remedied by careful blows with a rubber hammer on the
flange.
6. Screw the flange face of the stator to the machine housing and the flange face of the rotor
to the moving axis. In this case, observe the specified torques and the mounting technology
specifications.
A special mounting device is required when installing the stator and rotor on opposite flange
faces on the machine construction.
7. Completely remove any existing transport locks.
8. Remove the spacer foil. When the stator and rotor are correctly centered, the spacer film can
be easily removed by hand.
Keep the spacer film. You may need the spacer film for subsequent transport, packaging and
storage of the motor.
9. Check that the rotor can rotate freely. Ensure that the spacer film and any other foreign bodies
are completely removed from the air gap.
10.Connect the coolant lines.
11.Connect the power and signal lines.

Mechanical adjustment angle and EMF phase position

The EMF phase positions of motors connected in parallel must match one another. The
maximum deviation within a particular EMF phase position may be 10° (or +/-5°) electrical.
Otherwise, when mounting the motor you must correct the mechanical adjustment angle so
that you maintain the specified tolerance for the EMF phase position.
The relationship between the EMF phase position (electrical angle) and the mechanical
adjustment angle is shown in the following.
