Even if you're not an engineer, chances are that you have used an electric motor in some appliance. Motors that harness the power and magnetic force of magnets power everything from razors to fans to power tools and power tools to power toothbrushes, razors, and power tools.

What is the difference between an electric motor and a magnetic solenoid, then? An electric motor generates electricity through the interaction of the motor's winding currents with the magnetic field. The motor then converts the electrical energy into motion or mechanical power.

So why are electric motors necessary? Engineers choose an AC motor or a DC motor for five reasons.

Low cost

The simplicity of an electric motor's structure is a key advantage, especially in fixed-speed commercial applications or domestic applications where an AC power supply is easily attached.

Reliability

Because of their simplicity, electric motors can last a long time without needing to be maintained. For greater ease of use, some electric motors can even be self-starting.

Efficiency

The efficiency of electric motors is high, with ratings ranging from 50% to 95%. This is more than twice the efficiency of a diesel engine, and three times as efficient as a petrol engine.

Electric motors are more efficient than engines powered by fossil fuels. They don't require any servicing and can continue to work even at freezing temperatures. This makes them great for domestic and commercial refrigeration.

Excellent Speed Control

An electric motor's greatest advantage is its simplicity and efficiency. This motor can be controlled precisely, making it ideal for applications that require high speed precision.

Variable Torque

Some DC electric motors have a starting torque of up to 500%, making them suitable for applications such as electric cranes or trains.

Three-phase AC Induction Motors have self-starting torque. Single-phase motors however require additional starting power. An electric car is able to accelerate faster than high-performance petrol engines due to its ability to produce instant torque.
