Teaser text

Linear electrical machines are used in an ever-increasing number of applications. Recent areas that we have developed linear machine solutions for include down-hole pump applications and electrical launch systems. UNSW has also recently developed a new type of permanent magnet rotor that has its starting performance improved by including 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. Development of linear machine solutions to support what is a rapidly growing market.
