What are the two different forces acts in opposite direction on the rotor of single phase induction motor?

An induction motor has an AC power source applied to the stator and an AC source applied to the rotor, through slip rings. The rotor spins a sub synchronous speed, which creates the phase shift between rotor AC and stator AC. This phase shift (known as slip) is what creates the torque.

What is Cross field revolving theory?
Cross field revolving theory is the theory which discuss the cause of single phase induction motor not to be self starting. According to it, two different forces of same magnetude acts on the rotor in just opposite direction.Which makes the rotor standstill.
Define shear force?
Shear forces are ranged forces pushing one part of a body in a direction and another part in opposite directions. An example is when you pushed a deck of cards one way at the top and another at the bottom causing the cards to slide.
Where is flemings left hand and right hand rules are used in operation of induction motor?
For conventional flow (plus to minus) FLH rule is for motor action, and FRH rule is for generator action. So you can use FRH rule to determine the direction in which voltages are induced into the rotor by the rotating magnetic field, then use FLH rule to determine the direction in which the resulting forces, due to the rotor-bar currents, will act to rotate the rotor.
Why a three phase induction motor is self stating?
when you excite the 3-phase coils with an alternating supply,It produces a rotating magnetic field which interacts with the windings/conductor on the rotor & produces a current. According to Lenz's law the current induced is opposite in nature to the cause producing it & hence the magnetic field produced by this current will be opposite in nature to the rotating magnetic field in the stator.Hence due to interaction of these two forces a torque will be acting on the rotor which will make the rotor to rotate. Hence it is self-starting .
What is non concurrent force system?
In a concurrent force system, all forces pass through a common point. In the previous case involving the application of two forces to a body, it was necessary for them to be colinear, opposite in direction, and equal in magnitude for the body to be in equilibrium. If three forces are applied to a body, as shown in the figure, they must pass through a common point (O), or else the condition, SMo= 0, will not be satisfied and the body will rotate because of unbalanced moment. Moreover, the magnitudes of the forces must be such that the force equilibrium equations, SFx= 0, SFy= 0, are satisfied.
Is acceleration caused by two forces which are opposite to each other?
Acceleration is caused by unbalanced forces. They may or may not be opposite in direction. If they are, they must be different in size.
What is the Difference between like and unlike parallel forces?
Forces which are parallel and acting in same direction are called like parallel forces. Forces which are parallel and acting in opposite direction are called unlike parallel forces.
Forces that are equal in size but opposite in direction are .?
balanced forces
Forces that are equal in size but opposite in direction Are?
balanced forces
What forces equal in size but opposite in direction?
action-reaction forces
What are two forces that are equal in size but opposite in direction is?
Balanced forces
What is two forces that are equal in size but opposite in direction?
Balanced forces
What is two forces that are equal in size but opposite In direction are?
Balanced forces
What are two forces that are equal in size but opposite in direction?
Balanced forces
How are the size and direction of action-reaction forces are related?
Size: the same. Direction: the forces are in opposite directions.
Are 2 forces going in the same direction balanced?
No, they are not. The forces are balanced only when forces of equal magnitude are acting in the opposite direction.
Forces that are equal in size but opposite in direction are called unbalanced forces?
False forces that are equal in size but opposite in direction are called balanced forces. Unbalanced forces acting on an object cause the object to accelerate.
