Michael Faraday invented the principle of the electric motor in 1821. Several inventors tried turning this theory into a practical working model in the years afterward. However, the first truly practical Magnetic Motor Parts was not invented until 1871 by Zenobe Theophile Gramme. An electric motor is, in essence, a coil of wire on a rotating armature. The armature sits close to one or more magnets, so that it experiences a powerful magnetic field. When electric current is run through the coil it generates a magnetic field of its own which interacts with the field of the magnets, turning it.
1 Set a wheel, that will be the inner wheel, on a titling axis. The wheel itself should be of something that is non-conductive and can spin.
2 Attach magnets of some kind (ceramic bar magnets work well) equally around the rim of this wheel. Make sure that each of the magnets faces out for the same polarity.
3 Place a fixed outer ring around the inner ring. Make sure that this ring is also made of something non-conductive as you build a perpetual magnet Mechanical Parts.
4 Line the outer, fixed ring of the perpetual magnetic generator, with magnets that face in.
5 Make the inner ring of the perpetual magnetic generator you have built spin. As the inner wheel reaches the utmost portion of its revolution, the magnets on the outer ring should make the ring continue spinning until the next magnets set of opposing magnets face each other again.
6 Allow the inner ring of the perpetual magnet generator spin until the speed increases and energy is generated.

Synchronous Motor have a wide range of applications in industrial, commercial and domestic settings–in everything from small devices where precise timing is needed, like in clocks and tape players (Reference 1), up to large power generating facilities (Reference 2). A synchronous motor is defined by the difference between the actual speed of its spinning shaft and the theoretical speed of the magnetic processes inside the motor. This difference is sometimes called slip, which is just like torque, and is calculated using a series of computations with the final result being expressed in revolutions per minute.
When operating as a synchronous motor, the power is supplied to the machine by applying three-phase AC voltages at the terminals of the stator windings, in addition to the field windings of the rotor is fed by a voltage source.
Since the voltages applied to the stator windings are switched on and three-phase, will be circulated in the same alternating current of same frequency as the voltage, this current will produce alternating magnetic fields that also vary over time.
Furthermore, because the spatial arrangement of the Motor Stator Winding, magnetic fields with time-varying will also move in the stator, so that the magnetic field will rotate around the circumference of the stator with angular velocity proportional to the frequency of the alternating voltage applied to the windings .
So when one of the poles of the magnetic field generated by the field winding of the rotor interact with the rotating field resulting from the stator, will attempt to align with the pole of opposite sign, and as the pole of the rotating stator field is rotating, the rotor will come a torque of forces that will generate a torque so that the rotor turns and keep the fields in the field winding of the rotor and the stator rotating field line.
With the rise of torque, the rotor will rotate following the direction and speed of the rotating field of the stator, so the angular velocity of the synchronous motor is synchronized with the frequency of the alternating voltage applied to the stator windings.

Synchronous Motor naturally operate at a constant speed, and are most often used when an exact and stable speed is required. In this article we explain what a synchronous motor is, with their use as a microwave oven component as an example, how to tell if it has failed, and what to do to fix it.
A synchronous motor is an AC (alternating current) motor identified by two basic components, a stator and a rotor. The stator is the stationary part of the unit, as found in generators and other motors. The rotor is the rotating part of the unit as found in motors, generators, pumps, and alternators. It is similar to an alternator with a rotating field.
AC Motor Theory
The AC motor theory which enables a synchronous motor with Steel Shaft to run is based on Faraday’s law of induction. This law states that a magnetic field which changes rapidly produces an induced voltage. This induced voltage is the product of electromagnetic conduction, which occurs when voltage across a conductor moves through a magnetic field.
Synchronous Motor
A synchronous motor contains a rotor with coils that spin. These spinning rotors pass by magnets at the same rate as the magnetic field that drives it. Synchronous motors contain a stator, which is the stationary component of the rotor. The stator is the part of the magnet that helps to generate a magnetic field.
Synchronous Machines
Brushes and slip rings attached to the motor transfer current to the rotor, which contains poles that connect to each other and move at equal, or synchronous, speed. Synchronous motors are used in synchronous machines such as timers, electronic clocks and other devices that run on precise time.
