An electrical motor is such an electromechanical device which converts electrical energy into a mechanical energy. In case of three phase AC operation, most widely used motor is Three phase induction motor as this type of motor does not require any starting device or we can say they are self starting induction motor.For better understanding the principle of three phase induction motor, the basic constructional feature of this motor must be known to us. This Motor consists of two major parts: Stator: Stator of three phase induction motor is made up of numbers of slots to construct a 3 phase winding circuit which is connected to 3 phase AC source. The three phase winding are arranged in such a manner in the slots that they produce a rotating magnetic field after 3Ph. AC supply is given to them. Rotor: Rotor of three phase induction motor consists of cylindrical laminated core with parallel slots that can carry conductors. Conductors are heavy copper or aluminum bars which fits in each slots & they are short circuited by the end rings. The slots are not exactly made parallel to the axis of the shaft but are slotted a little skewed because this arrangement reduces magnetic humming noise & can avoid stalling of motor.

Operation principle of three phase power supply?
http://en.wikipedia.org/wiki/Three-phase_electric_power Click on this link from Wikipedia. It gives an excellent description of three phase power.
Working principle of synchronus motor?
A synchronous motor is a three phase motor, which uses a magnetic field created by permanent magnets or a DC electromagnet on the rotor (usually). The stator windings have 3 phase voltages applied, and coupled with the DC field, create a rotating magnetic field that drives the motor at synchronous speed.
What are the three types of phase on its final phase?
single phase, double phase & three phase
Working principle of 3 phase alternator?
A three-phase alternator has three sets of windings that produce three currents. The three currents make up the three phases. Together these produce the total AC output of the stator. An alternator is made up of a stator and a magnet rotor which is also known as the flywheel.
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
Which is not one of the three Principles of Training Principle of Overload Principle of Exercise Principle of Specificity Principle of Progression?
Principle of Exercise is not one of the three principles of training. The three principles are Overload, Specificity, and Progression.
Is three phase is ac or dc?
Three phase is ac
What is the principle and working of clevenger apparatus?
three fosters control the work of clevenger: boiling temperature of the distillator density and hydrophobic ability.
How do you start a three phase motor to a single phase power supply?
You don't. A three phase motor will not start unless it is connected to a three phase supply.
