A canned electrical machine is featured by having a can shield in air gap as partition. Considerable ohmic loss generated from the can (can loss) is the most highlighted feature. In this paper, an analytical electromagnetic model is proposed to analyze can loss. The model is divided into calculation of magnetic vector potential and modeling of magnetic saturation. In particular, the loss influenced by salient poles is discussed. The studied canned machine is a 3‐phase 12/8 switched reluctance machine as a pump drive. It is stressed that we do not judge and discuss performance of the machine developed but propose a modeling approach to improve the loss calculation approach. The developed method has been validated with simulation and experiments. The model gives accurate calculation of losses for electrical machines of high magnetic saturation effect.

An Alternative Method for Calculating the Eddy Current Loss in the Sleeve of a Sealless Pump

A sealless pump, also known as a wet rotor pump or a canned pump, requires a stationary sleeve in the air gap to protect the stator from a medium that flows around the rotor and the pump impeller. Since the sleeve is typically made from a non-magnetic electrically conductive material, the time-varying magnetic flux density in the air gap creates an eddy current loss in the sleeve. Precise assessment of this loss is crucial for the design of the pump. This paper presents a method for calculating the eddy current loss in such sleeves by using only a two-dimensional (2D) finite element method (FEM) solver. The basic idea is to use the similar structure of Ampère’s circuital law and Faraday’s law of induction to solve eddy current problems with a magnetostatic solver. The theoretical background behind the proposed method is explained and applied to the sleeve of a sealless pump. Finally, the results obtained by a 2D FEM approach are verified by three-dimensional FEM transient simulations.
