Induction motor

Induction motor - Wikipedi

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor a type of electric motor in which alternating current from a power source is fed through a primary winding and induces a current in a secondary winding, with the parts arranged so that the resulting magnetic field causes a movable rotor to rotate with respect to a fixed stator

Induction motor Definition of Induction motor at

An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding The Induction motor has two sets of windings (copper or aluminum wire coiled to form electromagnets). When the windings in the stator are energized it induces current in the windings in the rotor (this invisible force is call induction, learn about the concept of induction here)

Induction-motor drives are typically larger than permanent-magnet sine-wave wound motor-drives, for identical output powers; this is because of the rotor power loss in induction motors. Therefore, a provision may have to be made for forced cooling An induction motor is the most modest electrical machine from constructional point of view, in the majority of the cases. Induction motor works on the principle of induction where electro-magnetic field is induced into the rotor when rotating magnetic field of stator cuts the stationary rotor Induction motors in practice What controls the speed of an AC motor? In synchronous AC motors, the rotor turns at exactly the same speed as the rotating magnetic field; in an induction motor, the rotor always turns at a lower speed than the field, making it an example of what's called an asynchronous AC motor The Induction Motor block implements a three-phase induction motor. The block uses the three-phase input voltages to regulate the individual phase currents, allowing control of the motor torque or speed. By default, the block sets the Simulation Type parameter to Continuous to use a continuous sample time during simulation What is Squirrel Cage Induction Motor A 3 phase squirrel cage induction motor is a type of three phase induction motor which functions based on the principle of electromagnetism. It is called a 'squirrel cage' motor because the rotor inside of it - known as a 'squirrel cage rotor' - looks like a squirrel cage

Induction motor control is based on closed loop scalar control strategy. It can overcome the limitations of voltage source inverter and can offer better speed control and drive operation during voltage sags and normal working conditions An induction or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is induced by electromagnetic.

Induction Motor: Working Principle, Types, & Definition

The induction motor is the single excited motor, i.e., the supply is applied only to the one part, i.e., stator. The term excitation means the process of inducing the magnetic field on the parts of the motor. When the three phase supply is given to the stator, the rotating magnetic field produced on it
Induction Motor Model A reasonable model of an induction motor must first be identified before the parameters in that model can be deduced. A reasonable model to assume might be the one pictured in Figure 1. This model is meant to represent one phas
Uno dei motori elettrici più comuni, utilizzati nella maggior parte delle applicazioni, è noto come motore a induzione. Questo motore è definito anche come motore asincrono in quanto il rotore si accende sempre a una velocità inferiore rispetto al campo, rendendo il motore CA asincrono
An induction motor is based on the principle of induction of voltages and currents. The voltage and current is induced in the rotor circuit from the stator circuit for the operation. The equivalent circuit of an induction motor is similar to that of the transformer

Induction motor is a machine that simply operates on the induction type principle. It was invented by the scientist Tesla who earlier conducted several experiments on the working of the alternating current systems. Later, several experiments have been done to improve the performance of this type Induction motors are the most common kind of motor used in commercial production. It can be viewed as an AC transformer with a rotating secondary winding. The current in the rotor windings is induced from the current in the stator windings, avoiding the need for a direct connection from the power source to the rotating windings

Braking of Induction Motor: The three types of Braking of Induction Motor, namely regenerative, dynamic and counter current braking can be accomplished with induction motors also. Regenerative braking. When the rotor of an induction motor runs faster than the stator field the slip becomes negative and the machine generates power
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. As the current passes through the coils on opposite sides of the stator, a two-pole electromagnet is established, creating a two-pole motor
3-Phase induction machine construction • 3 stator windings (uniformly distributed as in a synchronous generator) • Two types of rotor: -Squirrel cage -Wound rotor (with slip rings) The rotating magnetic field • The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and.
The induction motor especially three phase induction motors are widely used AC motor to produce mechanical power in industrial applications.

The induction motor speed decreases by a few percent when the motor goes from no load to full-load operation. The full-load speed is a function of the motor design and power and is usually in the range of 94-99% of the synchronous speed; the difference is the slip. Figure 2 shows the typical construction of a squirrel-cage induction motor An induction motor always operates at a speed lower than the synchronous speed because the rotating magnetic field that occurs in the stator will generate flux in the rotor that will cause the rotor to rotate, but due to the delay of the flow current in the rotor with Current flow in the stator, the rotor will never reach its rotating magnetic field speed, that is, the synchronous speed Split-phase Induction Motor. The working principle of a split-phase induction motor is related to a polyphase induction motor. But the main disparity is, in single phase motor, it does not generate a rotary magnetic field whereas the polyphase generates simply a pulsating filed
