| Abstract |
This paper deals with the design of permanent magnet synchronous motors through a global
approach. Finite Element Analysis is used to valid the analytical sizing design. Analytical and thermal
model are developed. A program processing requirements such as outside sizes, inertia motor, heating
in steady operation and minimisation of torque oscillations enables to obtain a solution without
needing to use optimisation software. Then it is shown how in an mechanical system used for torque
assistance the design is constrained by mechanical characteristics, particularly the torque sensor
stiffness. Increasing this parameter enables to decrease the temperature in steady state operation. Two
examples of designs are presented with an aim of highlighting the interaction between torque sensor
stiffness and motor inertia and the consequences on the design. |
