dc.description.abstract | Permanent-magnet synchronous machines
(PMSMs) are well suited for high-speed (HS) applications
due to their high efficiency, power density, and dynamic
response capability. The heat extraction area decreases as
the speed increases, making thermal effects more dominant
at high speed. The temperature-dependent properties
of permanent magnets necessitate high-detail thermal
models. This paper presents a 2-D analytical model for a
HS PMSM magnet. The diffusion equation is solved where
three of the PM boundaries experience convection heat
flow; as the case is in radial flux machines. The heat
generated on the rotor surface due to eddy currents is also
taken into account. The model is verified using numerical
techniques and shows good correlation (within 1.5%). The
model is also validated through experiments performed on
a 4 kW, 30 000 r/min PMSM | en_US |
