This manuscript is about the nonlinear magnetic equivalent circuit model of a PMSM that is to be combined with converter, filters and wires models to run an electromechanical chain optimization process. The proposed model has been developed to ensure robustness towards geometrical, electrical and materials parameters and a compromise between accuracy and computation time. The finite element analysis...
This paper presents the design and optimization of an airliner fan motor to adapt it to a 540V HVDC network, starting with an existing BLDC motor. The motor reliability must be kept despite the increased constraint on the insulation due to higher voltage. A small tooth separating the slot in two is introduced, along with a fractional slot concentrated winding, allowing the phases to be kept separate...
This paper investigates the opportunity of making a natural convection permanent magnet motor for an airliner flight control actuator. The motor is designed to have a maximum lifespan and reliability: removing liquid or forced air cooling removes a fault source. A thermal analysis of the power that can be dissipated by natural convection and radiation is conducted. A winding with fully segregated...
