Answer:
Explanation:
speed of motor (N)=1500 rpm
power=4 hp = 
=2.9828 KW
service factor(k)= 2.75
now,
torque rating
Answer:
D. 90 degrees.
Explanation:
Torque is a rotational force which moves an object in other direction. There should be 90 degrees out of phase to start, run winding currents with each other. Torque is produced by the rotational motion of an object. The angle of the object must be 90 degrees set in order to create torque.
