Self-starting with the help of an auxiliary winding
(2 – s)
Phase splitting
A speed slightly below synchronous speed
40
0.7 lag
All of the above
Providing an additional winding on the stator called the auxiliary winding
In parallel
Develop starting torque
Both the main and auxiliary windings are placed on stator
By any one of the above three methods
Less than one
To cut off the starting winding at an appropriate instant
Rotor speed exceeds 70 per cent of its rated value
X/R ratio
Wither (a) and (b)
Starting winding
Result in more starting torque
