The first electric motor with enough power to be useful was invented was by Thomas Davenport. It was in the year 1834 that the invention occurred in Vermont state in the US. The motion devices which worked under electromagnetic fields had been developed by other people like Henry Joseph and Michael faraday prior to 1834. Henry and Faraday produced motors that could not be useful to human activities because they had low power. When in need of Electric Motors Toronto should be visited.
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 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.
In as much as there are different kinds of motors existing, they are made of similar components. For example, they each have a stator. This component is normally a magnet. It can be a permanent magnet or an electromagnet one created by insulated winding wires. The power of the magnet normally determines its strength as well. When using electromagnets, a magnet with more power can be created by using an insulated wire with more windings.
Another component is the rotor. This component sits in the middle of the magnet. It is acted upon by the magnetic field that is created by the stator. The effect of the stator on the rotor is that it rotates it. The rotation occurs because the poles of the rotor are attracted and repelled by the poles of the rotor. If the stator is very powerful, the rotation of the rotor also happens fast.
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.
The wire winding are mostly made of copper. Copper is a preferable material because of its ability to conduct heat and electricity most effectively. Additionally, even thin wires of copper are capable of transmitting high amounts of electricity. Another option is using aluminum although it has to be very thick in order to avoid failure when electricity passes through it.
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.
