Question # 1
What is back motor effect in generators?
- Ans 1: Back motor effect is the opposing torque produced due to the induced emf in the coil.When coil rotated a current is drawn through the coil.The magnetic field exerts two equal and opposite forces on left and right side of the current carrying coil,These forces are such that they produce a counter torque that oppose the rotational motion of the coil.This effect is known as back motor effect in generators.
