Electric Induction Motor

Electric Induction Motor

Electric Induction Motor belongs to the AC motors category. This type of motor possesses high flexibility in exhibiting various features such as speed control. When compared to DC motors, AC motors contain a much larger installed base with lots of advantages. Electric induction motors have low power demand at the start and it has controlled acceleration, adjustable operational speed, controlled starting current, adjustable torque limit, and reduced power line disturbances.

As the most common type of AC motors, electric induction motors apply electromagnetic induction from the magnetic field of the stator winding. This way they tend to produce an electric current in the rotor followed by torque. These motors are famous for their load capacity, In household appliances, a single-phase induction motor is commonly used since it works with smaller loads, while for industrial applications such as pumps, lifting gear, compressors, and conveyor systems, a three-phase induction motor is used because of greater loads.

An Electric Induction Motor is normally made without electrical connections to the rotor. It can be either squirrel-cage type or wound type. While the squirrel-cage type consists of a cylinder of steel laminations and its surface aluminum or copper conductors are embedded, in the wound-type, rotor windings are connected through slip rings to external resistance. Upon functioning, there occur the magnet fields are induced within the rotor. The stator works to produce a sync of the rotor, which is attracted to the magnetic field, and then it rotates with each half-cycle of alternating current.

Why it is called an induction motor is the reason for the magnetic field that is created in the stator, which then induces a magnetic field in the rotor. The electric induction motor has a shape just like a cylinder that is mounted on a shaft and it contains longitudinal conductive bars that are made of aluminium or copper. These bars are formed into grooves that are connected at both and form a cage-like shape. 

Uses:

The electric induction motor is used in household appliances such as fans while they are commonly used in kitchen appliances, water pumps, air conditioners, automobiles, and industrial machinery like boiler pumps and compressors.

FAQs:

Which motor is used in the grinder?

It is the universal electric motor that is used in the grinder. This motor works on both AC and DC currents. Wound with copper wire, this motor exerts a magnetic effect on the rotor.

Where do you use an electric induction motor?

Electric induction motors are the most economical, simple, and reliable in the world. They are mainly used for running washing machines, pumps, furnaces, winders, refrigerators, conveyors, and wind tunnels.

Which is the most commonly used electric induction motor?

The most commonly used electric induction motors are the 3-phase AC induction motors. These motors are very popular and are commonly applied in commercial and industrial applications. These motors are of two types: slip ring motors and squirrel cage motors. 

What are 3-phase induction motors used for?

The 3-phase induction motors are used for loads that duly require speed control. These motors are commonly used to run cranes, plunger pumps, crushers, compressors, elevators, and conveyors.

What is the working principle of induction motors?

The induction motors work on the principle of electromagnetic induction. Electromagnetic induction is the mechanism whereby the electromotive force induces across the electrical conductor.
