why the motor running in delta connection ? it can be in star?

Answer Posted / ramasamy

Motor running with star or delta depends upon the design,the same is given in the name plate.The reason for most of the motors are in delta is to limit the starting current by turn ON in star connection & than converting to delta connection to get the rated speed & torque. Where as it is not possible if the motor design is star. But now we get more of star connection design motor which are VFD & soft starter application.
