An electric device which functions by converting electrical energy into mechanical energy is referred to as an electric motor. One the other hand, an electric generator does the opposite by converting mechanical energy into electrical energy. Electric generators and electric motors share a lot in terms of properties. Several processes in the current society revolve around the functions done by these two machines. As such, they are heavily used. When one needs electric motors Toronto offers the perfect location to visit.
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.
Some models have permanent conductors and magnets included on stators and rotors respectively. The shaft rotates around an axis, so this part is always included. The rotor is held permanently in position by bearings. Bearings also ensure that its rotation is confined within its axis. The shaft can be extended outside through the included 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.
A safe distance is maintained between the rotor and stator in all motors. The air gaps that are included are usually made small. They must be made as small as possible so as to avoid negative impact on the motor if they were made large. In fact, the air gaps are responsible for the low power factor of motors. This makes the size of air gaps a very crucial factor in the designing of these devices.
Windings refer to wires that are laid in form of coils in the machines. Windings are usually wrapped around some cores that laminated magnetically. With this kind of arrangement they can easily create magnetic poles when supplied with electricity. The common magnetic pole configurations are of two types. The two are salient-pole machine and nonsalient-pole machine. When it comes to choosing magnetic pole configurations the various manufacturers of these devices have their own preferences.
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.
