ECONOMIC ELECTRICAL DRIVE FOR HIGHLY DYNAMIC APPLICATIONS IN THE TEXTILE INDUSTRY , THE VALVE ACTUATOR INDUSTRY AND THE VACUUM PUMP INDUSTRY

Objective


Within this project:
a switched Reluctance Motor 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 applications: 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.

The prototypes realized are within the 750W -3kWpk power range and operate in the speed range from 1500-20.000 RPM.

Although not evident, the design of the magnetic part of the motor has converged with the practical realisation and measurements. Several optimisations in winding distribution were found. Also the power electronic development has met no particular difficulties.
Concerning the control strategy and control board realisation, a compromise had to be found between soft- and hardware flexibility to enable control technqiue optimisations (software for overlap of phases) and hardware complexity.
Different approaches (microprocessor based, DSP based and programmable logic FPGA based) were evaluated and two different strategies were implemented.
