Even if not an engineer you may have used an electric motor on an appliance. Electric motors harness the power of magnets to drive fans, power tools, electric toothbrushes, and razors.

What makes an electrical motor different from a magnet solenoid? An electric motor generates energy through the interaction between the magnet field and winding currents. It then converts that energy into motion, or mechanical energy.

So why do we need to use electric motors? There are five main reasons engineers choose to use an electric motor over a conventional AC motor.

Low Cost

An electric motor's simplicity is key to its effectiveness in many applications. This is especially true for commercial applications that are fixed-speed and domestic, as well as commercial and domestic applications that require an AC power line.

Reliability

The simplicity of the design architecture means that electric motors are long-lasting and require minimal maintenance. Some electric motors can be set up to start themselves, which makes them more user-friendly.

Efficiency

High-efficiency electric motors have ratings between 50% and 95%. It's more efficient than a diesel engine but three times as efficient as a petrol one.

The electric motors produce no servicing requirements and are able to continue operating even when temperatures drop below freezing. This makes them ideal for both commercial and residential refrigeration.

Excellent Speed Control

The simplicity and efficiency of an electric motor are its greatest advantages. This type of motor is ideal for applications that require precise speed control.

Variable Torque

Some DC electric motors may have a starting force of 500% which makes them great for applications such as electric cranes, trains, and trains.

Three-phase AC-induction motors can self-start with torque. Single-phase motors, however, require auxiliary power. Because electric cars can produce instant torque, they can easily outperform high-performance petrol engines.
