Résultats exploitables
Within the project the following has been achieved:
a switched reluctance motor (SRM) is designed;
a power converter for SRM is designed;
a control strategy is designed and implemented;
prototypes are built to verify the design and to evaluate practical applications;
design rules are made in order to easy design other power ranges or other applications;
the design rules are checked towards the prototypes.
The following end user applications were evaluated in order to evaluate the performance (efficiency and dynamics) of the SRM:
textile drive application (high dynamics);
valve actuator application (very high stalling torque, high dynamics, torque control);
vacuum pump application, very high speed with low rotor losses (rotor efficiency);
general purpose drive (high torque, torque control, very dynamic, in order to be used for positioning control drives.
When comparing the SRM to classical motors, following advantages can be found:
principally, and when produced is the SRM a low cost motor (cheaper than induction motor);
excellent dynamic behaviour is confirmed;
very high starting torque;
low rotor losses, good efficiency;
low rotor inertion;
basic principle of SRM converter is simple.
The following disadvantages were found:
up to now no sensorless operation is demonstrated;
noise is inherent to the motor principle and is higher than an alternating current (AC) servo drive;
a 'new' motor technology which means that high investments are needed;
control technology for high dynamic application is not cheap for the moment because no specific integrated circuits (IC) exist.
