Nowadays most modern drive motors tend to be a.c. squirrel-cage induction motors because of their superior `power to weight' ratio. Hence most industrial motors are practically maintenance-free because of the absence of commutators and slip rings. There is however a danger that the electrical engineers are taking those motors too much for granted. Indeed the induction motors could only be very reliable if proper attentions are given. Moreover, it is well known that unexpected failures in the drives could result in many unpleasant situations. Coupled with the fact that the cost of testing these motors periodically is only a small fraction of the total maintenance cost in a drive system, any responsible electrical engineer should introduce a well-planned condition monitoring schedule to maximum the reliability of their drives.
