Typical cast aluminium rotor punching
Soft foot — Soft foot can play a major influence in the vibration of an induction motor. Although any motor can be adversely affected, 2pole machines are especially vulnerable to soft foot problems due to the eccentric electromagnetic forces within the air gap of their design.
There''s typically no way around it. At some time during a motor''s life, it is likely to experience high vibration levels. What''s behind this maintenance phenomenon? The cause may be an electromagnetic or mechanical imbalance, loose components, rubbing parts, bearing failure, or resonance. When a problem occurs, it is critical to quickly identify the source of the trouble and
Induction Motor : The most common electric motor found in industrial and commercial application is the AC induction motor. Induction motors work by electrically inducing an electromagnetic pole into the rotor. The magnetic field that surrounds the rotor appears to rotate which has the effect of pulling the rotor in the direction of rotation.
In the Vibration in an Induction Motor tutorial model, eddy currents are induced in the rotor by timeharmonic currents in the stator windings and rotation of the rotor. Induced currents in the rotor interact with the magnetic field that is produced by the coils to generate the driving torque on the rotor.
vibration which is created by an unbalanced magnetic pull due to air gap dissymmetry and does not change with load. On 2 pole motors, the twice line frequency vibration level will appear to modulate over time due to it''s close relationship with 2 times rotational vibration. Problems in a motor such as
