Even even if you’re not an engineer, chances that you’ve had a chance to use an appliance powered by electricity as its motor. Fans powered tools, power tools, razors and toothbrushes are powered by simple and clean electric motors which harness magnets’ power.
What differentiates an electric motor from the magnetic solenoid? Electric motors generate power by the interaction of the motor’s winding currents and the magnetic field. Then it transforms the electrical energy into mechanical or motion energy.
Why are we using electric motors? If you choose to go with an AC or DC motor There are five main reasons that engineers go for the flexibility and versatility of electric motors.
Reason #1. Low Cost
The primary benefit of the simple nature of electric motors’ design is the lower cost of using them in a variety of uses, particularly in fixed-speed commercial use as well as domestic and commercial applications in which the AC energy line can be simple to join.
This is why you’ll find the most efficient and cost-effective electric motor in household air conditioning, washing machines or vacuums. But when it comes to services like cooker oven, hob and repair of hoods, dishwasher repairs, repairs to tumble dryers repair of fridge freezers washer and drying machine repairs, the amount of expertise as well as the complexity of your task will need expert assistance.
Induction motors of this kind utilizes electromagnetic induction to create torque. It can be three-phase for industrial use as well as one-phase for home systems. This is also the type of technology found in e-bikes.
Reason #2. Reliability
Electric motors are able to last for a long operating life span, but require low maintenance requirements because of the simple design and construction. Certain electric motors can even be self-starters to make it easier for usage.
Electric motors are made up of a few moving parts and operate for as long as 30,000 hours roughly 3 1/2 years, without the need for major repairs. In reality, if the system is designed properly, the electric motor will not need replacement bearings for more than 10 years, which makes an electric motor very cost-effective.
Electric motors also function in extreme environments where dust, dirt as well as chemicals are in the air, making them suitable to be used in agricultural machinery such as.
Reason #3. Efficiency in Operation
Electric motors are extremely efficient, with ratings that range from 50 – 95 percent. This is more than twice as efficient as diesel engines, and three times more efficient than an engine powered by petrol.
As opposed to engines that operate on fossil-based fuels, electrical motors do not generate any of the requirements for maintenance and continue to function even in cold temperatures, which makes them perfect for refrigeration in both domestic and commercial settings.
Electric motors are also a part of the safety and comfort of working space. This is because they make minimal or no sound, have silent starting and stopping they produce no emissions and pose no danger to fire.
Reason #4. Excellent Speed Control
One of the main benefits of an electric motor is the ease and effectiveness of its design. The ability to control precisely the speed of motor is ideal for use in applications where precise speed control is needed.
Motors can also be equipped with the Silicon Controlled Rectifier (SCR) which lets you control the voltage and speed by just a single turn of an knob.
This is a great option for those which require precise torque and precise speed control – everything from robotics to milling equipment. Automated controls can add additional functionality and allow you to control the motor from a distance.
Reason #5. Variable Torque
Certain DC electric motors be equipped with an opening torque of 500 percent which makes them suitable for train tracks and electric cranes.
Three-phase AC induction motors are self-starting torque, whereas single-phase motors require an auxiliary starting power. The capability to generate instant torque implies that electric vehicles can beat even the most powerful petrol engines easily.
Engineers have barely just scratched the limit of the possibilities AC as well as DC electric motors are able to do. In the near future it’s likely that all things from space rockets to motorbikes can be made powered with extremely clean, efficient and low-maintenance electric motors because of their strength and versatility.
