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.

Abstract: The invention relates to a closed rotary electrical machine incorporating a cooling system comprising two internal fans secured on the shaft of the rotor, at the two ends of the rotor. Each fan faces the inner face of a flange comprising fins orient the flow of air created by the internal fans and can capture the heat from operation of the machine. A casing which contains the rotor and the stator of the electrical machine is sealed by two flanges. The cooling system also comprises external cooling for cooling the casing and flanges, comprising air or liquid.
