The electrical parameters are maintained. X
The smooth running characteristics and machine running noise have not
deteriorated.
X
The motor foundation has no cracks and indentations. (*) X X
(*) You can perform these checks while the motor is running or at a standstill.
Additional checks may also be required according to the system-specific conditions.
NOTICE
If you detect any deviations during the inspection, you must rectify them immediately. They
may otherwise damage the motor.
9.2.3 Main inspection
● While the motor is running, check that:
– The stated electrical characteristics are being observed
– The smooth running characteristics and machine running noise have not deteriorated
● Once the machine has been shut down, check that:
– The motor foundation has no indentations or cracks
– The machine is aligned within the permissible tolerance ranges
– All the fixing bolts/screws for the mechanical and electrical connections have been
securely tightened
– The winding insulation resistances are sufficiently high (Page 50)
– Any bearing insulation has been fitted as shown on plates and labeling.
– Cables and insulating parts and components are in good condition and there is no
evidence of discoloring
