EDrives Library
The reliable modelling of electric drives is vital for many industrial applications from the automotive to the aerospace industry.
In the EDrives library one can find models of electric drives for
- Permanent magnet (PM) synchronous machines
- Synchronous reluctance machines
- Induction machines with squirrel cage
The library is designed to support phase numbers greater or equal to three. All electric machine and control models consider copper (Joule) loss, core loss, friction loss, stray load loss and PM loss.
The library supports three levels of abstraction:
- Quasi static electric machines and power converters (neglecting electrical transients)
- Transient electric machines with averaging power converters (neglecting switching effects)
- Transient electric machines with switching power converters
Levels of Abstraction
- Quasi static electric machines and power converter (all electrical time transients are neglected)
- Transient electric machines with averaging power converters
- Transient electric machines with switching power converters
Modularity
- No re-building of models
- Easy change of level of abstraction
- Consistent use of parameter records
Further Developments:
- Active mains converters with voltage oriented control
- Extended loss models of power converters
- Advanced machine models
- Multi level inverter configurations
• Redundancy and reliability of electric drives
• Full and hybrid electric vehicles
• Electric aircrafts
• Industrial drives
