PRINCIPLE OF DESIGN OF FOUR-PHASE LOW-POWER SWITCHED RELUCTANCE MACHINE AIMED TO THE MAXIMUM TORQUE PRODUCTION

Martin Lipták

   This paper deals with the design of a low-power four-phase SRM optimized to maximum torque performance. The design is made from the point of view of the space available for motor location. The outer dimensions such as outer stator diameter and effective length of iron are input values. The influence of operational parameters as well as the rest of geometrical dimensions upon motor performance is discussed. Some of the geometrical topologies of this SRM type are investigated by various speeds. The moment of switching is aimed to maximum torque production. The operation of the motor as well as motor converter and control strategy are described.

Keywords: SRM design, torque production, one-pulse operation, chopping operation
