Novel Optimized Shape and Topology for Slotless Windings in BLDC Machines

Yves Perriard, Adrien Jean-Michel Thabuis, Guillaume Paul-André Burnand, Douglas Martins Araujo

Slotless windings are commonly used in small size high-speed electrical brushless dc machines. Unlike slotted windings, forced to follow the direction of slots, slotless windings can be freely arranged in the airgap. This represents several opportunities f ...

Small scale very high speed slotless permanent magnet motors

Guillaume Paul-André Burnand

This research work has been triggered by an industrial project aimed at modelling and manufacturing a small-scale very high speed motor. Very high speed electrical motors offer the main advantage of reducing the size of a system. Indeed, at constant output ...

Improved Analytical Model of Hyperelastic Magnetic Membrane

Yves Perriard, Yoan René Cyrille Civet, Louis Antoine Masson, Cécile Gisèle Aimée Jeannine Cuchet, Guillaume Paul-André Burnand

This paper proposes an analysis of multi-factor fabrications of magnetic membranes. In order to acquire some knowledge about the influence of fabrication factors, an analysis is performed using a Design of Experiment (DoE) methodology. The latter is applie ...

Validation by Measurements of a Windage Losses Model for Very-High-Speed Machines

Christian Köchli, Yves Perriard, Guillaume Paul-André Burnand, Douglas Martins Araujo

When designing a very-high-speed (VHS) machine, it is crucial to evaluate the windage losses accurately, because they are an important part of the total losses. It is therefore important to validate a reliable model, further used for the design and optimiz ...
