Induction motors are a special kind of machine that make things move with electricity. This video will explain what induction motors are, how they work, the different types, where they are used, the good and bad and problems that can arise. Let’s begin with the fundaments of induction motors.
Induction motors operate by creating a magnetic field that rotates a rotor. This rotor spins a shaft that gets things moving. Induction motors are everywhere, from washing machines and fans to refrigerator compressors. They are also employed in factories to run machines that produce cars, toys and the like.
The most common types of induction motor are single phase and three phase motors. They are found in smaller appliances such as blenders and vacuum cleaners, which both need the maintain a particular speed and operate for a limited duration. Three-phase motors are employed in larger systems and machines such as air conditioners and pumps. Each one has its share of pros and cons — there's no one right type, it all depends on what job it needs to accomplish.
One phase induction type motors are commonly used in domestic machinery such as mixers, fans, and washing machines. Three-phase induction motors can be found in factories for conveyor belts, compressors, and water pumps. These are selected for their reliability and efficiency in driving these devices.
Single-phase induction motors are a bit easier to install and use, and are therefore a good choice for items like irrigation pumps and appliances in smaller buildings. Three-phase induction motors are being signposted to, as they are stronger and therefore, more efficient, which fits well with industrial applications. But they are less straightforward to use, and require a special power supply to function.
While choosing an induction motor, consider the size of the appliance or machine it is to be attached to. Single-phase motors are ideal for small appliances, and three-phase motors are better suited for larger machines. An important factor to keep in mind is the amount of power the motor requires and the efficiency of the motor for the type of work for which it is used.
