It is not surprising to find that this type of electric motor is so popular, when one considers its simplicity, reliability and low cost. In the last decade, it has become increasingly common practice to use 3-phase squirrel cage AC induction motors with variable voltage variable frequency (VVVF) converters for variable speed drive (VSD) applications.
3/7/2018· ELECTRIC MOTOR An electric motor is an electromechanical device that converts electrical energy to mechanical energy. The mechanical energy can be used to perform work such as rotating a pump impeller, fan, blower, driving a compressor, lifting materials etc. 3.
Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.. A three-wire three-phase circuit is usually more economical than an equivalent two-wire ...
Construction of Three Phase Induction Motor. Like any electric motor, a 3-phase induction motor has a stator and a rotor.The stator carries a 3-phase winding (called stator winding) while the rotor carries a short-circuited winding (called rotor winding).. Only the stator winding is fed from the 3-phase supply.

The construction of a synchronous motor (with salient pole rotor) is as shown in the figure at left. Just like any other motor, it consists of a stator and a rotor. The stator core is constructed with thin silicon lamination and insulated by a surface coating, to minimize the eddy current and hysteresis losses.The stator has axial slots inside, in which three phase stator winding is placed.
A three-phase motor has two main parts: the rotor, which turns, and the stator that turns it. The rotor is often called a squirrel cage because it consists of a circular network of bars and rings that look a bit like a cage connected to an axle. The stator consists of a ring with three pairs of …

The three-phase AC induction motor is a rotating electric machine that is designed to operate on a three-phase supply. This 3 phase motor is also called as an asynchronous motor. These AC motors are of two types: squirrel and slip-ring type induction motors. The principle of operation of this motor is based on the production of a rotating ...
11/27/2019· The three phase induction motor is the most widely used electrical motor.Almost 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 …
The magnetic paths of the leg a and c are greater than that of leg b, the construction is not symmetrical, and there is a resultant imbalance in the magnetising current. Shell type Three Phase Transformer. The shell type 3-phase transformer can be constructed by stacking three single phase shell transformer as shown in the figure below.
The single-phase induction motor can be made to be self-starting in numerous ways. One often-used method is the Split Phase motors. Another method is the Capacitor Start Induction Run Motors. We know about the activity of a capacitor in a pure A.C. Circuit. When a capacitor is so introduced, the voltage lags the current by some phase angle.

The three-phase current (phase shifted for 120˚ between each other) generates a more uniform RMF than two-phase currents. This is the most common type of motor, due to its low cost, easy maintenance, robustness, overloading and wide range of rotating speed.
Single phase Induction Motors: Single-phase a.c supply is commonly used f or lighting purpose in shops, offices, houses, schools etc.. Hence instead of d.c motors, the motors which work on single-phase a.c. supply are popularly used.
3 phase squirrel cage Induction Motor is one of the most popular types of AC electric motor which achieve the electromechanical energy conversion through stator and squirrel cage rotor by electromagnetic induction.. That's why it's called squirrel cage induction motor. Normally, we use the motors in industrial drives because they are rugged, reliable and economical.
11/27/2019· An electrical motor is an electromechanical device which converts electrical energy into mechanical energy. 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 device.These types of motors are known as self-starting induction motors.
1/8/2019· Three-phase. Stator for each type has the same number of windings. The single-phase and three-phase motors are the most widely used. The simplified cross section of a single-phase and a three-phase BLDC motor is shown in figure below. The rotor has permanent magnets to form two magnetic pole pairs, and surrounds the stator, which has the windings.
Construction of Three Phase Induction Motor: Figure 8.1 shows the construction of three phase induction motor.A 3 phase induction motor has two main parts (i) stator and (ii) rotor.The rotor is separated from the stator by a small air-gap which ranges from 0.4 mm to 4 mm, depending on the power of the motor.
An electric motor can be defined as; it is one kind of machine used to convert the energy from electrical and mechanical. Most of the motors work through the communication among the electrical current and magnetic field of the motor's winding for generating force in the form of shaft rotation.
