How Induction motor work
An induction motor is a type of electric motor in which the armature (the rotating part) is electromagnetically coupled to the stator. The rotor, the part that rotates, is called the inductor.
Induction motors are widely used in applications where direct current can be used. Induction motors require electrical power at a frequency work how induction motor much higher than their rotational speed, hence the name “induction”.
A typical induction motor has a commutator on its armature and an electromagnetic field winding on its stator that’s how induction motor work
The magnetic field produced by these windings induces an alternating current in the armature windings. The frequency of this AC depends on many factors including:
The number and Characteristics of the windings;
The relative position of the coils;
The number of pole pairs in each coil;
whether there is any DC present; and
how well insulated each coil is.
Induction motors are used for applications where the motor will be in constant action. The operation of an how induction motor work is similar to that of a simple DC motor work, but with one important difference — instead of turning a shaft, an induction motor has an iron core that spins within a magnetic field.
Examples of applications where induction motors are used include industrial machinery, aircraft engines, and electric vehicles.
Induction motors can be made in different sizes and shapes depending on the application. For example, a large induction motor work may have multiple stator coils while smaller ones tend to have just one or two.
They also come in many different types depending on the type of material they’re made from and the type of magnetic field they create.
In an induction motor, the rotor spins on a magnetic field. When the rotor spins, it induces eddy currents in the stator ac windings, which produce an electromagnetic force called torque. The rotor and stator are usually made of laminated steel, with copper windings wrapped around them that’s how induction motor work.
Induction motors have several advantages over other types of motors:
They can be made much smaller than permanent-magnet ac motors.
Induction motors can produce higher speeds than magnetically powered motors without increasing the cost or size of the motor.
A brushless DC motor is an inductive type of electric motor that uses both permanent magnets and electromagnets to create rotational motion,
As opposed to using only electromagnets (such as those used in classical AC machines). induction motor work
Brushless DC motors are used in many applications where low speed or high power are required—for example, in camera lenses or electric cars
