“…As for three-phase case, this control mode needs to transform the real electrical variables expressed into a stationary reference frame into fictitious variables expressed into multiple one or twodimensional dq rotating reference frames. For a n-phase machine, the first harmonics of electrical variables can be regarded as DC components and the use of PI controllers in the current loops leads to null steady state errors [11].…”

“…Our work focuses on acting on the space harmonics whose interactions are different for a multi-phase machine in comparison with those of a three-phase machine. It has been shown, initially for particular multiphase machines with concentrated windings [9], and more recently for a wider family of n-phase machines [10] with N identical and regularly shifted windings, that families of space harmonics can be defined. These families do not interact amongst themselves.…”

The specific constraints due to the PWM supply of multiphase machines are also taken into account during the design phase. All the defined constraints are expressed in a simple manner by using a multimachine modelling of the multiphase machines. This multimachine design is then applied in order to meet the specifications of a marine propeller: verifying simultaneously four design constraints, an initial 60-pole 3-phase machine is converted into a 58-pole 5-phase machine without changing the geometry and the active volume (iron, copper and magnet). Firstly, a specific fractional-slot winding, which yields to good characteristics for PWM supply and winding factors, is chosen. Then, using this winding, the magnet layer is designed to improve the flux focussing. According to analytical and numerical calculations, the five-phase machine provides a higher torque (about 15%) and less pulsating torque (71% lower) than the initial three-phase machine with the same copper losses.
