Besides their high efficiencies, they are also notable for their reliability and freedom from the need for maintenance — virtues stemming from their lack of moving parts. AC became standard partly because transformers have these attractive properties, relegating DC to special purposes.

Alan F. Murray,H. Martin Reekiely efficient; in fact large (> 1 MW) induction motors have efficiencies of up to 98%. Their biggest drawback hitherto has been their small range of operating speeds, though this is changing with the introduction of solid-state, variable-frequency drives. Table 17.1 shows typical characteristics for a small and a large squirrel-cage motor.
