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 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.
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.
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.
Beside the count of the wire windings, the amount of current passing through the electromagnet will also determine the motor strength. Increasing wire windings increases the magnetic field strength and this in turn creates more power in the motor for rotating the rotor. This whole set up is insulated to avoid any danger that the users may be exposed to by this 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.
