Acceleration

In electric motors, when the rotor is considered to be stable, with the resultant force and zero torque, it will be the favorable and most appropriate time to reverse the direction of current in the coil. In this way, the poles will approach, so that the repulsion force becomes stronger.

Since the coil exhibits an angular movement to the left, it can remain rotating to the same side with a rotational inertia, and the new torque generated by repulsive forces will aid in the maintenance and acceleration of the rotational movement.

At the right moment, the reversal of the current direction becomes a fundamental condition for the maintenance of the proper torques, so that it can guarantee the correct functioning of the motors.   52095

Even after the coil has rotated 180 degrees, the movement will be continuous, since in the vertical, it has a rotation of 270 degrees, in this way, will cancel the torque and the current will have its direction reversed, repeating the cycle again. These attractions and repulsions if coordinated effectively will cause the rotor to rotate, although the way such torques are struck may vary between different types of motors.
