  • Split Phase Motor Construction, Working, Torque -

    The vector diagram for the split phase induction motor is shown in the Figure B. As the winding resistance of starting winding is high, the angle between voltage and current I s is small. Similarly the inductance of the running or main winding is high therefore the angle between I m and V is very large but less than 90 0. The starting torque in the split phase motor is directly proportional ...
