Induction Motor Construction Understand how it works and the most common styles to make the best selection by Blake Bailey 10/15/2020 Induction motors come in a wide range of sizes and styles, with some machine styles dictated by limited design choices and others resulting from negotiations between user and manufacturer Generally, the guiding factors for how a motor is A three phase induction motor is a type of AC induction motors which operates on three phase supply as compared to the single phase induction motor where single phase supply is needed to operate it The three phase supply current produces an electromagnetic field in the stator winding which leads to generate the torque in the rotor winding of three phase induction motor having magnetic fieldThreePhase Induction Motor – Construction, Working, Types rotor Construction and Working Principle of a Rotor In a threephase induction motor, once an AC is applied to the rotor then the windings of stator strengthen to generate a rotary magnetic fluxThe flux generates a magnetic field in the air gap among the stator the rotor to induce a voltage for generating the current throughout the barsRotor : Construction, Working Principle,Types and Its Three phase induction motor are simple in construction as compared to DC Motorsor synchronous motor They are widely used in electric motors in industry The several features of induction motors are: A laminated stator core carrying a polyphase winding A laminated rotor core carrying either a cage or polyphase winding, the latter with shaftmounted slip rings polyphase winding Three phase induction motor: construction Engineering Almost 90 percentage of induction motors are squirrelcage type, because this type of rotor has the simplest and most rugged construction imaginable and is almost indestructible The Rotor consists of cylindrical laminated core with parallel slots for carrying the rotor conductors which, it should be noted clearly, are not wires but consists of heavy bars of copper, aluminium or alloysThree Phase Induction Motor: Construction, Working Principle
Types and Amazing Applications of Induction Motor
The rotor of an induction motor can be a squirrel cage rotor or wound type rotor Used in different applications, induction motors are also called Asynchronous Motors This is because an induction motor always runs at a slower speed than synchronous speed The speed of the rotating magnetic field in the stator is called synchronous speed Induction machines are the most frequentlyused type of Basic construction The AC induction motor comprises 2 electromagnetic parts: Stationary part called the stator; Rotating part called the rotor, supported at each end on bearings; The stator and the rotor are each made up of: An electric circuit, usually made of insulated copper or aluminum, to carry current; A magnetic circuit, usually made from laminated steel, to carry magnetic Basic construction of 3phase AC induction motors you A phase wound rotor of three phase induction motor is also called slip ring rotor and the motors employing this type of rotor are known as phase wound or slip ring induction motors Slip ring rotor consists of a laminated cylindrical core having semiclosed slots at the outer periphery and carries a 3phase insulated windingThree Phase Induction Motor Construction your electrical Three phase induction motor are simple in construction as compared to DC Motorsor synchronous motor They are widely used in electric motors in industry The several features of induction motors are: A laminated stator core carrying a polyphase winding A laminated rotor core carrying either a cage or polyphase winding, the latter with shaftmounted slip rings polyphase winding Three phase induction motor: construction Engineering A phase wound rotor of three phase induction motor is also called slip ring rotor and the motors employing this type of rotor are known as phase wound or slip ring induction motors Slip ring rotor consists of a laminated cylindrical core having semiclosed slots at the outer periphery and carries a 3phase insulated windingThree Phase Induction Motor Construction your electrical
