An electric motor refers to an electric device that operates by converting electrical energy into mechanical energy. The reverse process, which involves converting mechanical energy into electrical energy is done by another machine called an electric generator. The two machines have a lot of properties in common. These two machines find a lot of use in the modern society as many processes revolve around them. When in search of electric motors Toronto should be given priority.
In most cases, the operation of these machines involves the interaction between magnetic fields in the device and winding currents to produce force. In the transportation industry, in a phenomenon known as regenerative braking, an electrical motor is also used in reverse. Here, it causes the locomotive to stop by changing mechanical energy into electricity.
The desired effect is realized after a system is created from the many independent parts of machine that work together. Rotor, bearings, commutators, air gap, windings, and stator are some of the independent parts included in a motor. The part that moves is called the rotor. Rotors are responsible for turning the shaft thus creating mechanical energy. This part has conductors for conveying current to the magnetic fields of the stator thereby leading to power generation that turns the shaft.
Depending on the design the stators can have permanent conductors while the rotors are designed with permanent magnets. An axis in normally included so that the shaft can rotate around it. Bearings are included to ensure the rotor is permanently held in its position and that it rotates within its axis. The shaft extends to the outside through the bearings.
Stators make the stationary components of the electromagnetic circuit of the machine. They may be made of permanent magnets or windings. The core of the stator is composed of several sheets of thin metals, which are called laminations. The purpose of the laminations is to reduce losses of energy, which would otherwise occur if solid cores were used instead.
In every motor some distance is allowed between the stator and rotor. The included air gaps are very tiny. Air gaps are made small as possible to avoid the negative impact caused on the motor by large air gaps. Interestingly, air gaps account for the low power factor of electric motors. As such, the issue of air gaps is a very important aspect in the design of motors.
Windings refer to wires that usually get laid in coils in the machine. They are usually wrapped around laminated iron magnetic cores, allowing them to creaet magnetic poles once electricity passes through them. There are two main types of magnetic pole configurations. These two configurations are salient-pole machine and the nonsalient-pole machine. Various companies have different preferences for which magnetic pole configuration to use.
Electric motors find use in a wide range of household, commercial, and industrial appliances. Some of the appliances they are used in include disk drives, machine tools, power tools, household appliances, blowers and pumps, and industrial fans among many others. A motor can receive its power from a DC source as well as an AC source. Classification of these machines may be done based on various factors such as internal construction, electric power source type, and application.
