In some strange occurrences, you may sometimes end up in certain emergency  cases  where you are caught unexpectedly in urgent situations that would demand immediate action. One of such unexpected situation in the field of industrial technology is the  absence  of three phase power source to supply a three phase motor, where the only  available  means is the most commonly found single phase power supply voltage. It is important to note here that it is theoretically possible to run a three phase motor using single phase power source. This is  applied  by connecting the single phase voltage to any two of the three wiring terminals of the three phase AC motor, leaving one wiring terminal open. However, this type of  application  would require helping the motor to start by hand, this is to help the motor rotate until it reaches enough momentum to run on its own with a single phase voltage supplied to only two of the three motor terminals. ...

Introduction It has been said that if the Ancient Romans, with their advanced civilization and knowledge of the sciences, had been able to develop a steam motor, the course of history would have been much different. The development of the electric motor in modern times has indicated the truth in this theory. The development of the electric motor has given us the most efficient and effective means to do work known to man. Because of the electric motor we have been able to greatly reduce the painstaking toil of man's survival and have been able to build a civilization which is now reaching to the stars. The electric motor is a simple device in principle. It converts electric energy into mechanical energy. Over the years, electric motors have changed substantially in design, however the basic principles have remained the same. The phenomena of magnetism, AC current and basic motor operation will be covered.  Magnetism A permanent magnet will attract and hold metal objects ...
