Ever thought about how stuff works in things like fans, refrigerators, and air conditioners? They use a special motor type, called a "shaded pole induction motor. “ It is a motor that is found in household products because it is simple and not too costly.
Some of the following are due simply to the fact that shaded pole induction motors are so simple. They have fewer parts than other motors, making them simple to build and repair. They’re also inexpensive, and require little energy, so they’re perfect for home appliances.
These engines operate with the magnetic field induced by flowing of the electricity in the main coil. This magnetic field causes the rotor to rotate. The shaded coil assists the motor in starting by altering the magnetic field and enabling it get that little extra umph to start working.
Shaddowed pole induction motors are only one form of induction motor. There are others as well: split-phase, capacitor-start, three-phase motors. Each design has it is reason for use and it is pro’s and con’s.
As compared to other kind of motors, shaded pole induction motors are simple and are generally the least expensive. They are well-suited for jobs that don’t require a lot of muscle or a hard start. For heavier tasks, other motors could prove more efficient.
