Abstract
The disclosure relates to a motorised air circulation valve including a gear motor, a valve body, and a rotary shaft provided with a shutter. The rotary shaft is rotated by the gear motor, where gear motor includes a set of reduction gears, a brushless electric motor formed by a rotor having N pairs of magnetised poles connected to a pinion of the set of reduction gears, and the pinion drives an output wheel rigidly connected to the rotary shaft. The electric motor includes a stator part having at least two coils, the stator part having two angular sectors, alphaand alpha, of respective radii Rand R, with Rbeing greater than R, and the center of the radii and the angular sectors being defined relative to the center of rotation of the rotor. The angular sector alphais defined by the angular deviation between the axes of the first and last coils considered in a circumferential direction of the motor, the angular sector alphais less than 180° and includes the coils, the sector alphais devoid of a fully fitted coil, an end of the gear motor defines a side of the gear motor, and the angular sector alphaof the stator part is positioned facing the side.
