description |
A series of systematic studies are carried out to investigate the influence on torque density and
power density on machine speed rating. Several series of permanent magnet
machine designs are established using an array of different electrical and
thermal design constraints. The paper demonstrates that torque density in
permanent magnet machines tends to decrease with speed rating due to complex
interplay between electromagnetic and mechanical considerations, e.g. fixed
winding current density, fixed split ratio etc. Interesting trends are observed,
including cases in which there is an optimum rotational speed in terms of power
density, beyond which the power density starts to decrease with increased speed
rating. |
