Checking the rotor thickness

}
Danger!
When the rotor thickness is checked, the motor must not run.
1. Remove fan cover and cover ring if attached.
2. Measure rotor thickness with calliper gauge. If a friction plate is attached, ensure
a flanged edge at the outer diameter of the friction plate.
3. Compare measured rotor thickness with minimally permissible rotor thickness
(values ^ 49).
4. If required, exchange the entire rotor. Description ^ 49.

Checking the air gap

1. Check the air gap "s " near the fixing screws between the armature plate and
L
stator using a feeler gauge (^ 49).
2. Compare air gap measured to maximally permissible air gap "s
3. If required, set air gap to "s
