The Prevalent And Important Applications Of Electric Motors

By Stephen Bell


We are technically operating in an extremely industrialized world. This is why newfangled contraptions are being constantly invented to cater to more and more specialized operations. An example is Electric Motors Toronto.

These are not new developments, however. In point of fact, they have been around in the nascent years of the nineteenth century. Despite its technical sounding appellation, it is not some isolated contraption and is actually found everywhere. What we dont usually appreciate is that we are constantly using it, perhaps even all the time.

The commonality is that these devices are being used to convert electrical energy into functional mechanical energy. This may be observed in pipeline compression, ship propulsion, and other great considerable applications. It goes without saying that most industrial operations in the present age are heavily reliant on the nifty capabilities of electric motors.

The whole point of this equipment is to turn an electrical input into mechanical energy. This input actuates rotation inside the motor, which is also further powered by its magnetic fields and circulating currents. Amperes Force Law is the theoretical principle behind this tool. It postulates how mechanical force is produced between the reaction of the magnetic field and electric current present inside the contraption.

There are many ways to bring about this phenomenon. The technology can be powered by direct current, as in batteries, and alternating current, through power grid and some such electrical generators. Some might be confused between this equipment and that of the generator. The answer is that they are distinctly different, in that a generator operates the reverse way, by turning mechanical into electrical energy.

The components include a rotor, which is the moving part of the equipment. It is the one which rotates the shaft to produce mechanical power and is also essentially conductive. The bearing supports it, enabling it to turn on an axis. The windings and magnets are studded in the stator, which is the non moving part. A so called air gap separates the rotor and stator from each other.

The windings are coiled wires wrapped around a laminated iron core that enables the operation of magnetic poles. The commutator is the nifty mechanism used to switch the input. In the end, the principle of the electric motor can be narrowed down to magnetism, that which enables the equipment to create motion. But the efficiency, identified through the torque, is determined by the physical properties, involving both the voltage production and the wire length, since that implies more coils in the stator and therefore a stronger magnetic field.

The electric motor types are many and sundry. Tips of the iceberg include the AC powered ones, which utilize alternating currents, used in large automation processes. Theres also the DC geared, which are often used in relatively small and compact devices, as with flat screen TVs. Servos are used in robotics and steppers in high precision operations.

Before you purchase a motor for your operations, look at several telling factors. Makes sure its the right kind of equipment for your application. Look at the frequency, voltage output, size, weight, and also the noise requirements. Basics involve the rotation direction, maximum speed range, and the running load capabilities. Choosing the right kind of motor will preclude heavy maintenance and downtime in the offing.
