In this recent decades, there was a significant growth in the applications of nano technology in the field of electrical and electronics engineering. In this research paper, the estimation of the different types of losses on a normal and nano coated three phase induction motor was done and hence the results were compared with each other. From these researches, it found that the mechanical losses were reduced by 33.33% in the motor after nano coating whereas stator iron losses were reduced by 13.8%. Stator losses were reduced up to 16.7% by coating the windings of the motor with the enamel filled with nano fillers of SiO2 and Al2O3 whereas rotor copper losses were high in the nano coated motor. The output mechanical power developed by the normal motor was increased by 39% with the application of the nano fillers to the enamel used for the coatings of the windings of the motor whereas the gross rotor torque was improved by 42%. The power factor of the motor was also improved by nano coating by 15.5%.

A 1-phase induction motor usually has a complicated windings design which compares to polyphase induction motor. In addition, a large capacitor start is required to operate the motor. It is an expensive way to operate the motor if it compare to polyphase induction motor. So, a new innovation method is required to make the motor more simple and cheaper. This research is purposed to study a new winding design for a single-phase capacitor motor. Winding design of the motor was conducted to a simple winding design like a 4-phase induction motor that has four identical windings. The comparator motor that use in this study was a Three-phase induction motor with data 1400 RPM, 1.5 HP, 50Hz, 380/220V, Y/Δ, 2.74/4.7A, 4 poles, that had the same current rating which the proposed method. The result showed that the motor design on this proposed method could be operated at 88.18 % power rating with power factor close to unity.

A three-phase induction motor will continue to operate when a disturbance of some sort causes the source voltages of the motor to become unbalanced. When an induction motor is operated at unbalanced voltage supply the performance characteristics like efficiency, power factor, input power, output power and losses are affected.  The single-phasing occurs when one phase fails as a result of a fuse blowing, protective device opening on one phase of the motor, open phase on one terminal of the motor or other causes. This paper will analyze the operation of a 3-phase induction motor under normal balanced source voltages first, then under single phasing experimentally in order to follow a comparative approach.
