Design and implementation of a digital control system for an axial flux switched reluctance motor

Abstract

Nowadays, besides the rapid growth of different areas like the mechanical and electrical ones, it is possible to identify a particular effort to develop new motors including new electrical drives and control systems. Additionally, these equipments are being designed to give them the maximum efficiency as the energy cost is continuously increasing. With this in mind, some results related to a particular switched reluctance motor, are presented. The airgap between its poles are distributed in such a way that they are parallel to the rotation axis. Such structure is little studied by researchers. On the other hand, in order to maintain a low ripple torque, a particular algorithm is proposed which consists in imposing motor currents with a special format. The implementation of this strategy was made using two microcontrollers, one to determine the position and speed of the rotor while the second impose the appropriated current to the motor windings. This strategy has been successfully tested to control the speed of the rotor in a simple feedback loop.
