<p>The motor reducer has a polyphase electric motor comprising a stator (1) excited by electric coils (15-17), and a rotor (14) with magnetic poles. The stator has angular sectors (alpha1, alpha2) with respective radii (R1, R2) whose ratio is comprised between 1.2 and 2. The sectors comprise wide teeth (2-7) and narrow teeth (8-13) extending radially from an annular crown. The wide teeth have a width greater than or equal to twice the width of the narrow teeth. A notch has a width greater than that of one narrow tooth. The sector (alpha1) is lower than 220 degree and regroups the coils.</p> |
