Abstract: The present invention relates to a stator of an electrical machine comprising slots (2) and coils (5, 5′) connected to electric phases. The layout of coils (5, 5′) of an electrical phase includes a parallel combination of branches (4), wherein two coils (5, 5′) are combined in series. Furthermore, loops of two coils (5, 5′) of two branches (4) in parallel are inserted in each slot (2).

Abstract: An electric machine includes an alternating current electric motor comprising two semi-windings and an inverter comprising at least two inverter branches which are electrically connected each one to a respective semi-winding. The machine also includes a control unit which provides respective control signals to the two inverter branches so that they induce two alternating currents of frequency in the respective semi-windings. The control signals of the two inverter branches have a frequency smaller than the frequency and are also reciprocally out of phase by 180° relative to the frequency. This allows reducing ripples of the overall alternating current resulting from the sum of the two alternating currents provided by the two semi-windings.

Abstract: The invention relates to a rotary electrical machine (100) with an integral magnetic sensor (101) of the angular position of the rotor (150). The sensor includes a rotary part (108) with magnet (102) fixed to the end (160b) of the rotation shaft (160) at the rear of the machine, facing a fixed part (103) including Hall effect sensors and mounted on a fixed support (106) connected to the frame of the machine. The machine includes a bearing (104) centered on the axis (X), separating the rotary and fixed parts of the sensor. This bearing, fixed to the shaft and to the metal support of the fixed part of the sensor, and preferably in contact with the rotary part, constitutes a new mechanical reference close to the sensor. The invention provides accurate and robust position information independently of mechanical and magnetic disturbances to which the shaft may be subjected.
