High Efficiency Three Phase Induction Motor IE2 is made of gray cast iron, and its efficiency meets the requirements of GB18613- standard energy efficiency level 3 and IEC60034-30 standard IE2 efficiency level requirements. Read More.

As per new standard IEC 60034-30-1 published in March , four level of motor efficiency are defined for three-phase induction motors. The updated standard IEC 60034-30-1 includes IE1, IE2, IE3 and the fourth efficiency level IE4. Furthermore 8-pole motors and an extended power range are now included in the standard. Efficiency classes

Working Principle of Three-Phase Induction Motor. The stator winding is overlapped at 120˚ (electrically) to each other. When a three-phase supply is given to the stator winding, the rotating magnetic field (RMF) induced in the stator circuit. The speed of the rotating magnetic field is known as synchronous speed (NS).

ATT WE Series compromises of 3-phase, squirrel cage, IE2 high efficiency (IEC 60034-30-1) motors in Cast Iron frame. ATT WE series motors are all-purpose and highly efficient, making them well-suited for general application machines. Our WE series induction motors are widely recognized by their optimum performance even in challenging work conditions. Our WE Series

This Scheme classifies induction motors into three efficiency bands, from Eff3 (lowest) to. Eff1 (highest). It enables all OEMs (Original Equipment.

A very large number of single phase motors are sold each year in the horsepower range of about 1/20 to 3/4 horsepower for air moving fan applications, 

The motor is produced by the phenomenon that the electrical coil is pressured to rotate in the magnetic discipline. AC motors are divided into two kinds: synchronous alternating current motor and induction motor. The stator windings of a few-phase AC motors are essentially 3 coils divided by 120 levels, which are linked by triangle or star.

30/08/  · A 3-phase induction motor is an electromechanical energy conversion device which converts 3-phase input electrical power into output mechanical power.. A 3-phase induction motor consists of a stator and a rotor. The stator carries a 3-phase stator winding while the rotor carries a short-circuited winding called rotor winding.The stator winding is supplied from a 3
