Starting torque can be obtained in the case of a single phase induction motor with identical main and auxiliary windings by connecting

The following starting method for an induction motor is inferior view of the poor starting torque per ampere of the line current drawn:

Higher synchronous reactance is preferred in the present day alternators, because one can have

A three phase alternator is wound with a 60 degree phase-spread armature windings and develops 300 kVA. If the armature is reconnected utilizing all the coils for single phase operation with a phase spread of 180 degrees, the new rating of the machine is
