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.
Mostly, the operation of these electric devices entails interaction of magnetic fields in the machine and the winding of currents to generate force. In a phenomenon referred to as regenerative braking under the transportation industry, electrical motors are applied in reverse. It works by converting mechanical energy into electricity thus causing the locomotive to stop.
This device is usually comprised of several independent parts that work together as a system to achieve the required effect. Some of the common parts that make up the motor are rotor, bearings, stator, air gap, windings, and commutators. The rotor is the moving part of the system and it delivers mechanical power by turning the shaft. Rotors are made with conductors for carrying current that interacts with magnetic fields of the stator leading to the generation of the force 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.
These devices have many uses in industrial, household, and commercial appliances. Electric motors are included in appliances like machine tools, disk drives, blowers and pumps, household appliances, industrial fans and power tools. They can derive power from by both AC and DC sources. Various factors can be used in classification of these machines including application, electric power source type, and internal construction.
