Linear Electrical Machine Drives
Linear electrical machines are used in an ever-increasing number of applications , with solutions developed for down-hole pump applications and electrical launch systems . Recent developments also include a new type of permanent magnet rotor with improved starting performance via the integration of a conducting ladder-slot arrangement . This new type of rotor allows the machine to rapidly accelerate under the action of induction principles to the synchronous speed where the permanent magnet flux can then be used to increase the force . |
Competitive Advantage • Leading-edge rotor technologies developed for specific applications
• Experience in a wide range of conventional and advanced linear machine control techniques ( vector and scalar control , sliding-mode control , and modelpredictive control )
• Ability to rapidly develop and prototype controllers
• Custom linear machine design and prototyping
Impact • Development of linear machine solutions to support a rapidly growing market
• Tuning improvements and robust control techniques improve the tracking and performance of controllers and yield faster responses
