In this article, we present the modeling of the synchronous cascade control of an industrial ring motor of the Brasserie de Kinshasa; based on nonlinear equations based on the operations of varying speeds in real time. Conventional control, where the mains voltage is applied directly to the ring motor does not offer the possibility of varying the speed of said motor. The objective of this article is to vary the speed of the motor beyond synchronism. Conventional control, where the mains voltage is applied directly to the ring motor does not offer the possibility of varying the speed of said motor. The mathematical model based on the nonlinear equations of the electromechanical quantities of the motor facilitate the evaluation of the performance of the slip ring motor. These models confirm that the variation in the speed of the ring motor is closely related to the power of the converter associated with the stator and the rotor.
