A test can be made which does not require the removal of the rotor to detect broken or open rotor bars.For large motors, bearing wear and the resulting deviation in concentricity of the stator and rotor can be detected by measuring the air gaps over several points around the periphery of the rotor.The electrician must be very careful when placing a new bearing on the shaft so that neither the bearing nor the shaft is damaged ( 8).
