The first powerful enough electric motor to be developed was produced by someone named Thomas Davenport. The invention happened in the state of Vermont in the United States in 1834. Other people I history that had developed motion devices that used electromagnetic fields were Joseph Henry and Michael Faraday. Motors developed by Faraday and Henry were not powerful enough to be of any use to any human application. When one needs Electric Motors Toronto offers the perfect location to visit.
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.
An electric motor can be powered by alternating or direct currents. They can be categorized therefore as AC and DC motors. The AC varieties came after the DC models were invented. Although each of them has merits and demerits, they are both powered by electromagnetic fields. The motors can also be categorized by other factors aside from the electric current that the motor uses.
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.
In most cases, copper wire is the one used to form the wire windings. Copper wire is preferred because it is a good conductor of electricity and heat. Also, thin copper wires are capable of transmitting higher amounts of electricity without failing. Aluminum wires can be used, but they have to be thicker so that they do not fail 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.
