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.
These motors by Henry and Faraday however, were major aids in the process of inventing the device by Davenport and even the ones being used currently. Commercially, the motor acquired its success several years later in 1873. There was however a variety of these devices already created by many different pioneering engineers before this time.
An electric motor can be powered by use of alternating or direct currents. Therefore, one can classify these devices into AC and DC motors. Invention of DC motors was done earlier before that of AC motors. Both of these devices have their own disadvantages and advantages although they both rely on the power of electromagnetic fields to operate. Apart from being classified according to the form of electricity used by these devices, other criteria for classification also exist.
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.
A motor can burn out if it is made to operate for a very long time. This situation occurs when there is failure in the insulation encircling the wound wire. The failure creates contact between the wires. When contact occurs, there is a short in the wires, leading to the device burning out. A device that has burned out cannot function.
