Product Description

Three Phase AC Induction Motor

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 magnetic field.

3 Phase Induction Motor Construction

These three-phase motors consist of a stator and a rotor and between which no electrical connection exists. These stator and rotors are constructed with the use of high-magnetic core materials in order to reduce hysteresis and eddy current losses.

 

3 Phase Induction Motor Construction

Stator frame can be constructed using cast iron, aluminum, or rolled steel. The stator frame provides necessary mechanical protection and support for stator laminated core, windings, and other arrangements for ventilation. The stator is wounded with three-phase windings which are overlapped with one another at a 120-degree phase shift fitted into slotted laminations. The six ends of the three windings are brought out and connected to the terminal box so that these windings are excited by three-phase main supply.

These windings are of copper wire insulated with varnish fitted into insulated slotted laminations. At all working temperatures, this impregnated varnish remains rigid. These windings have high-insulation resistance and high resistance to the saline atmosphere, moisture, alkaline fumes, oil, and grease, etc. Whichever suits the voltage level, these windings are connected in either star or delta connections.
 

The rotor of the three-phase AC induction motor is different for the slip-ring and squirrel-cage induction motors. The rotor in the slip-ring type consists of heavy aluminum or copper bars shorted on both ends of the cylindrical rotor. The shaft of the induction motor is supported on two bearings at each ends to ensure free rotating within the stator and to reduce the friction. It consists of a stack of steel laminations evenly spaced slots that are punched around of its circumference into which un-insulated heavy aluminum or copper bars are placed.

A slip-ring-type rotor consists of three-phase windings that are internally starred at one end, and the other ends are brought outside and connected to the slip rings mounted on the rotor shaft. And for developing a high-starting torque these windings are connected to rheostat with the help of carbon brushes. This external resistor or rheostat is used at the starting period only. Once the motor attains the normal speed, the brushes are short-circuited, and the wound rotor works as a squirrel cage rotor.

     Induction furnace is used for smelting or insulating ferrous metals, non-ferrous metals, sponge iron, such as scrap iron, scrap steel, copper, aluminum and so on. Complete working equipment such as continuous casting machine, rolling mill, mainly used for the production of billet, steel bar, angle steel, H-beam, I-beam, etc. Using KGPS, IGBT, single or double power supply technology, PLC (Siemens) can be realized throughout the monitoring.
