An essential part of the intelligent management of an industrial plant is the predictive maintenance to be applied for all the equipment, including also electrical machines. Several fault detection techniques were developed in the past years for the most frequently used rotational electrical machines, but only a few papers were published in the field of condition monitoring of special electrica...

A new simplified mathematical model for a switched reluctance motor (SRM) driving a centrifugal pump was developed and experimentally validated. The simplified mathematical model was suitable to simulate the performance of the SRM–pump system and to design its controller. The new simplified model was determined based on the assumption that the SRM phase inductance profiles have triangular wavef...

In industrial automation and robotic applications, direct-drive motors represent a suitable solution to friction and backlash problems typical of mechanical reduction gears. Variable reluctance (VR) motors are well suited for direct-drive implementation but, because of the strongly nonlinear electromechanical characteristics, these motors are traditionally designed as stepper motors. The main a...

This paper presents a new approach used for switched reluctance motors (SRM) speed control. Two nonlinear controller, one is variable structure with sliding mode controlled type (VSC) and the other is PI-like fuzzy controller (FLC), define a new control structure. The VSC acts mainly in a transient state which is increasing system stability limits. But, PI-like FLC controller acts in the steady...
