6 3-phase AC motor becomes
too warm in continuous
operation
Load too high
Measure power input*
Voltage too high or too low
Check main voltage and voltage drop up to
electric drive*
Single-phase instead of 3-
phase operation
Check power input of all three lines*
Short circuit in coil
Check supply line for interruption and, if
necessary, eliminate or have rewound
Ventilation impaired
Remove dust, chips or the like from air paths
Re-adjust air deflectors
Prevent intake of warm exhaust air
Rotor grinds in stator
Adjust or replace bearings
Foreign matter in air gap
Dismantle rotor and clean motor

7 Jerky start
Short circuit in the rotor winding
Eliminate short circuit or have rewound
Connection to PEN conductor
instead of to outer conductor
Check connections and, if necessary, correct

Interruption in winding or
asymmetry of resistances in
rotor or defective short-circuiter
Measure resistances
Have motor repaired by qualified staff

11 3-phase AC motor shows
excessive no load current
Terminal voltage too high
Measure main voltage*
Air gap possibly increased
during repairs
Measure air gap at three points and, if
necessary, set correctly
