Energy Meter Energy meter is an instrument which measures amount of electrical energy used by the consumers. Utilities install these instruments at every place like homes, industries, organizations to charge

Electrical motor in general is an electro-mechanical device that converts energy from electrical domain to mechanical domain.A synchronous electric motor is an AC motor in which, at steady state,[1] the rotation of the shaft is synchronized

Both synchronous and induction machines work on AC supply, ie; they are AC machines. For AC machines, the basic requirement is to create a rotational magnetic field so that the
