For Electric Motors Toronto Is Worth Visiting

By Karen Murphy


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.

The generation of force in these devices depends on magnetic fields interacting in the machine and the winding of currents. Basically, these devices operate on this principle. The reverse application of electrical motors is used in the transport industry under a phenomenon known as regenerative braking. It involves conversion of mechanical power into electricity which in turn stops the locomotive.

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.

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.

The stationary components of the electromagnetic circuit of the device are where stators are included. Their windings or magnets can be permanent. The stator has a core that is made of lots of thin metals known as laminations. Thin metals are used so as to reduce energy loss which would happen if solid cores were used.

Usually, a motor is made with a distance between stators and the rotors. This distance is what is referred to as a the air gap. Air gaps are made to be as tiny as possible because making them large would impact the motor negatively. The lower power factor of motors is as a result of the air gap. As such, it is a very important design aspect in the device.

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.
