A motor that follows the repulsion theory is one of the simplest motor that has a field which is composed of a spread winding, stored in spaces, all within an even layer in the stator and also an armature that carries a winding that is scattered and also attached with single piece of commutator. The coiled up stator is responsible for producing the primary field, which is attached to a main source of current supply. Though the framework or the winding of the rotor is not linked up with the main source to the circuit.However, the brushes are arranged at such an angle with a leading flux part which are placed in a specific angle with each other. This is how the circuit is being short-circuited and represented in the fig given below fig. 12.

Thus we can conclude from the above explanations that the rapidity of the repulsion motor is influenced by the position of the brush. Thus the regulation of speed of such machines can be delivered by intensifying the brushes on any movable object that is changeable from its position with the help of a handle that is placed on the armor that is placed at the other end of the motor. Thus if there is the need of remote control, then the handle can be operated with some simple mechanism withbars and balls.
Otherwise, to make the motor bounded, or to control by a remote than a minimum
distance that must be covered, where the regulation of its acceleration may be attained by using a peripheral series resistance which is also provided with an immovable gear for brushes.
Atkinson repulsion motor. Atkinson repulsion motor is the alteration of a simple repulsion motor into Atkinson repulsion motor, where the stator meandering contains two windings which are positioned at ninety degree angles with one other and are attatched in series with one another, which is represented in Fig. 13. The most help fulparts found by using this particular method and determine the rotational direction that can be overturned by altering the links of the windings in stator. There is absolutely no need for altering the brushes by merely changing the switch will be enough, and this is represented in the given Fig. 13.
It is also noticeably found that the stator is connected with electricity to the rotor. Thus the reimbursed repulsion motor cannot directly be operated with high-power supply, as it was analogous with the single repulsion motor. In the given Fig. 15 it shows a characteristic speed-torque is shown with the same features for a repulsion motors having a single phase.
Compensated repulsion motor. This compensation repulsion motor can enhance the power of the device, and itis possible only by supplying a supplementary brush set which is also represented in theFig. 14.

Thus the axis of single pair which is named as BB for one set of brushes that overlaps with the coiled stator. The brushes are usually short-circuited and the second pair of brushes, bb is positioned at ninety degrees with the previous one and is linked in a sequence with the coiled stator.
