Abstract

In this paper, an analytical approach is proposed in developing a lumped parameter thermal model for the stator coils of naturally cooled axial-flux tooth-coil permanent magnet machines. The model comprises one tooth, the coil around it, and the air channels between coils and the teeth supporting structure; each component is subdivided into cuboidal or arc subelements. An expression of the convective exchange coefficient is proposed to take into account the radial position of each tooth. Experimental results validate the proposed model, which can also be used in the design stage of a machine.

Subjects
Vibration -- Control, Seismic waves -- Properties, Electrical equipment and supplies -- Design and construction, Electrical equipment and supplies -- Mechanical properties, Electrical machinery -- Design and construction, Electrical machinery -- Mechanical properties, Magnets, Permanent -- Properties, Business, Computers, Electronics, Electronics and electrical industries
Abstract

Some electromagnetic and thermal aspects concerning special permanent magnet machines, employed in damping seismic oscillations in structural systems, are examined. The power generated by the machine during a seismic event is regulated by a suited converter and delivered to an external resistor. Some modeling features and selected simulations are examined, together with test results obtained by a prototype. Some special tests, aimed to identify the thermal parameters of the machines, are presented and discussed. Index Terms--Axial flux permanent magnet (PM) machines, concentrated winding electrical machines, electrical and thermal modeling, seismic vibration damping.
