This revolving magnetic flux also called as rotating magnetic field which induces an e.m.f. in the rotor by mutual induction. ... *here it is the detailed information about induction motor construction and important part are explained with clean images.
(See Induction motor alternator) This is a singly-fed induction generator, having electrical connections only to the stator windings. A wound rotor induction motor may also act as a generator when driven above the synchronous speed.
The rotor core mounts on a steel shaft to form a rotor assembly. The wound rotor is another type of induction-motor-rotor construction. A major difference between the wound rotor motor and the squirrel-cage rotor is that the conductors of the wound rotor consist of wound coils instead of bars.
An induction motor or asynchronous motor is an AC motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction …
Construction of Squirrel Cage Induction Motor All induction motors have a rotor and a stator. Basically, it is the construction of rotor which makes Squirrel Cage Induction Motor different from Wound Type Induction Motor.
Greater the number of poles, lesser is the speed of the motor and vice-versa. When 3-phase supply is given to the stator winding, a rotating magnetic is produced. This rotating field induces currents in the rotor by electromagnetic induction.it is static part of construction of induction motor.
The above classification is based on rotor construction of induction motor. In squirrel cage the rotor is of closed winding type that is the rotor is constructed with short circuited copper bars and and all are connected at the end by end rings.
This motor is called the wound-rotor induction motor or slip-ring ac motor. CONSTRUCTION DETAILS A three-phase, wound-rotor induction motor consists of a stator core with a three-phase winding, a wound rotor with slip rings, brushes and brush holders, and two end shields to house the bearings that support the rotor shaft.
Induction motor works on the principle of electromagnetic induction. When three phase supply is given to the stator winding, a rotating magnetic field of constant magnetic field is produced. The speed of rotating magnetic field is synchronous speed, N S r.p.m.
Contents: Construction of Stator; Construction of Rotor; A three phase Induction motor mainly consists of two parts called as the Stator and the Rotor.The stator is the stationary part of the induction motor, and the rotor is the rotating part.
As a general rule, construction of a induction motors consist essentially of two main parts : a) a stator and b) a rotor. In rotor construction, there are two types of motors are coming.. Squirrel cage rotor motor
Synchronous motor and induction motor are the most widely used types of AC motor. Construction of a synchronous motor is similar to an alternator (AC generator). A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range, generally rated between 150kW to 15MW with speeds ...
Figure. Induction motor construction Figure. Induction motor components. Stator construction The stator of an induction motor is laminated iron core with slots similar to a stator of a synchronous machine. Coils are placed in the slots to form a three or single phase winding.
b) Wound rotor – It has 3 phase windings, usually Y connected, and the winding ends are connected via slip rings. Wound rotor are known to be more expensive due to its maintenance cost to upkeep the slip rings, carbon brushes and also rotor windings. Basic Induction Motor Concepts. The Development of Induced Torque in an Induction Motor
Construction of Dc motor. Construction of Dc motor nearly looks like the construction of Dc generator, originally when the Dc machine starts working we can't identify whether it's a Dc generator or motor, briefly Dc motor consists of:. Stator: it's the stationary part containing the field winding and receives the supply. Rotor: which is the rotating part.
FIGURE 8 Per-phase induction motor equivalent circuit. Locking again at the rotor part of the equivalent circuit in Figure 8, the resistor R r represents the resistance of the rotor winding. The power used by it is the power lost in the resistive heating of the rotor winding.
Fig. 1. Physical construction of the squirrel-cage induction motor: (a) cross section showing stator and rotor, (b) rotor construction. 1. Basic operation of the induction motor As previously shown, the phase displacement between the voltages applied to the stator windings produces a travelling MMF or rotating magnetic field in the uniform air gap.
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 rotor ...
Slip-Ring or Wound-rotor Induction Motors. Construction Of Squirrel Cage Induction Motor. Any Induction Motor has a Stator and a Rotor. The construction of Stator for any induction motor is almost the same. But the rotor construction differs with …
The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.
Electric motor - Construction of induction motors: The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors.
Construction of Induction Motor:. The stator of an Construction of Induction Motor is similar to that of a synchronous machine and is wound for three phases, modem practice being to use the two-layer winding. Figure 9.1 shows the stator of an induction motor. Two types of constructions are employed for the rotor wound-rotor and squirrel-cage rotor.
Construction of Three Phase Induction Motor. Three phase induction machine can work as an induction generator and induction motor. But for most of the application, its performance as an induction generator is unsatisfactory.
Like all motors, a three-phase induction motor contains a stator (the stationary part) and a rotor (which rotates). Each contains electrical windings that carry current and thus creates a magnetic field. The interaction of the magnetic fields creates the torque that rotates the rotor and the load.
