![]() ![]() By the commutation actions of the brush and the commutator, the coil current can be reversed as shown in Fig. Thus the coil will rotate continuously in that direction. However, when the coil is at the position shown on the right, if the direction of its current is reversed, then the force produced on the conductors on both sides is reversed and thus, the force on the coil will remain in the same direction of clockwise. Since the force produced on the coil is not produced continuously in one direction, the coil also cannot rotate in the same direction continuously. ![]() When the coil rotates and comes to the position as in the figure on the right, the force produced on the conductors on both sides will return the coil again to its initial position as shown in the left side of Fig. ![]()
