Abstract

The paper’s aim is to present an optimization algorithm to design rim driven (RD) machines. It calculates the RD geometry that allows to produce a desired average torque with respect of several constraints. It tests different combinations of design variables. The best combination respecting the specifications and the dimensioning constraints will be used for the determination of the whole geometry of the machine. To validate the operation of this algorithm, we propose to design a RD pump. The designed pump's nominal characteristics are respectively a torque of 10 N.m and a power of 5 kW. The electromagnetic performances of the RD pump motor are assessed by the finite element method (FEM). The comparation shows a conformity of about 95 % between algorithm outputs and FEM results. This validation allows to validate the proposed method for the design of Rim driven systems.
