How to know motor winding is star or delta connected without see the information table and winding connection ?
Answer Posted / srinivasa rao talasila
Star connected or star running designed motor winding
resistance is some what high compared to delta running
designed motor.
Exambple 5.5KW star designed motor is having a resistance
of 1.2 ohams,same in delta is 0.45 ohams like that
Not exactly the same but there is a difference in
resistance.
