Popis: This paper describes the performance of an external-rotor split-phase induction motor for use in such applications as ceiling fans (although the pole number would be much higher than the 2-pole machine studied here). This machine has short axial length with respect to its diameter. The auxiliary winding is only used to start the machine and it is wound orthogonal to the main winding and connected in parallel to it using a centrifugal switch. The paper highlights how an external can, which connects the two end-rings, can be used to improve the motor performance. The paper describes a 2-D finite element analysis (FEA) of the machine to show the performance and also to describe the pulsating torque of the machine. © 2007 IEEE.
