This work deals with the representation of three-phase and three-limb transformers in two dimensions using FEMM (finite element methods on magnetics). The transformer magnetization curve is obtained using the magnetization characteristic for the silicon steel used when assembling the transformer core, associated to the air gaps inherent to the assembling process. A method for the calculation of the...
The vertical electromagnetic force affects the design of the air bearing or magnetic bearing of a synchronous permanent-magnet planar motor (SPMPM), whereas the static vertical electromagnetic force is one of the important components of the vertical electromagnetic force. This paper discusses the problem of modeling the static vertical force of the SPMPM analytically. First, we obtain an analytical...
