Almost 80 of the motor is a three phase induction motor among all motors used in industries.

3 phase ac induction motor diagram. The most popular type is the 3 phase squirrel cage ac induction motor. If you are interested in our product line of. Many single phase motors having two windings can be viewed as two phase motors since a capacitor is used to generate a second power phase 900 from the single phase supply and feeds it to the second motor winding. The input power given to an induction motor is in the form of three phase voltage and currents.

This video explains how to wire a three phase induction motor to an external electricity source. The induction motor especially three phase induction motors are widely used ac motor to produce mechanical power in industrial applications. Power flow diagram and losses of induction motor power flow diagram of induction motor explains the input given to the motor the losses occurring and the output of the motor. Therefore the induction motor is the most important motor among all other types of motor.

The three phase induction motor is the most widely used electrical motoralmost 80 of the mechanical power used by industries is provided by three phase induction motors because of its simple and rugged construction low cost good operating characteristics the absence of commutator and good speed regulation. In three phase induction motor the power is transferred from stator to rotor. As the current passes through the coils on opposite sides of the stator a two pole electromagnet is established creating a two pole motor. Applying a phase to each of the electromagnets in turn creates the rotating magnetic field that is strong.

Difference is that transformer is an alternating flux machine while induction motor is rotating flux machine. Rotating flux is only possible when 3 phase voltage or poly phase which is 120 degree apart in time is applied to a three phase winding or poly phase winding 120 degree apart in space then a three phase rotating magnetic flux is. In theory induction motors can have any number of phases. It is a.

The power flow diagram of an induction motor is shown below. 3 phase ac induction motors are comprised of the stator and rotor. During operation a current is applied through the stator which induces a magnetic field and leads to the rotation of the rotor. In the case of three phase ac alternating current operation the most widely used motor is a 3 phase induction motor as this type of motor does not require an additional starting devicethese types of motors are known as self starting induction motors.

An electrical motor is an electromechanical device which converts electrical energy into mechanical energy. Target motor theory 31 3 phase ac induction motor drives the ac induction motor is a workhorse with adjustable speed drive systems. In a 3 phase ac induction motor there are three stator windings each usually in two halves with the rotor winding short circuited by end rings. The rotational speed of the shaft and the applied torque is dependent on the operating frequency and the number of pole pairs in the motors windings.

Induction motor is a generalized transformer. It also shows the difference between delta and star connections used to connect the motor coils.
