Thomas Davenport was the first person to invent an electric motor that was powerful enough to be useful. This invention was done in the US in the state of Vermont in the year 1834. Michael Faraday and Joseph Henry were the other people that according to history, developed motion machines that operated on electromagnetic fields. The motors that these two individuals developed did not have adequate power for them to be useful for any human activity. When in search of Electric Motors Toronto should be given priority.
However, the motors that Henry and Faraday developed were very instrumental in leading the way to the device developed later by Davenport and even those in use today. Commercial success in the motor was achieved in later years in 1873. By this time, there were several variations of this device that were developed by several different pioneering engineers.
Both direct and alternating currents can be used to power an electric motor. Thus, these devices can be classified into DC and Ac motors. The DC varieties were developed first before AC models came into existence. Each type has its own advantages as well as disadvantages, but they both depend on the power of electromagnetic fields. Besides classification based on the time of electricity the device uses, there are other classifications as well.
Even though different types of motors are in existence, they basically have the same components. For instance, every motor has a stator. The stator is usually a magnet of some form. The magnet may be a permanent one or it may be an electromagnet, which is formed by winding insulated wires. How powerful the magnet is usually determines the strength of the device as well. In the case electromagnets, using more windings of insulated wire creates a more powerful magnet.
The rotor is another component found in motors and stays at the center of the magnet. There is a magnetic field produced by the stator that acts upon it. The stator rotates the rotor. This process of rotation happens as a result of the pole attraction and repulsion to the poles of the stator.
The amount of current passed through the electromagnet also determines the power of the motor. More wire windings form a magnetic field that is stronger. A very stronger magnetic field generates more power to turn the rotor in the device. Insulators are used to enclose the whole setup so that risks to the users of these devices can be eliminated.
Mostly, copper wires are used to create the wire windings. The reason why copper wires are preferred is that they are good heat and electricity conductors. Thin copper wires can also transmit higher electricity amounts without failing. Although aluminum wires can be used, they must be thicker to prevent them from failing when electricity is passed through them.
When a motor is run for too long, it may burn out. This happens when the insulation around the wound wire breaks, causing the wires to make contact. Upon making contact, the wires short and cause the device to burn out.
