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.
Although, there are various kinds of motors available, they essentially have similar components. For example, a stator is installed in all kinds of motors. Usually, the stator is a kind of magnet. The magnet might be an electromagnet or a permanent one. Electromagnetic magnet is created by winding insulated cables on a core. Also, the strength of the magnet determines the amount of power in the device. A more powerful magnet is created by use of more windings of insulated wires in electromagnets.
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 strength of the motor also depends on the amount of current being passed in the electromagnet besides the number of windings of the wire. More windings of the wire create a stronger magnetic field. If the magnetic field is strong, there is more power generated in the device to turn the rotor. This entire setup is enclosed using insulators so that it does not pose danger to people who use the device.
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.
