A rotary electric machine includes a stator housed in a housing, the stator having a stator body formed by a stack of stator laminations, the laminations are generally non-circular and being angularly offset with respect to each other, so as to form spaces with the housing, the housing having ducts for the flow of a coolant, and said spaces also being used for the flow of the coolant.

Stator for a rotating electrical machine

A drive device for a handling trolley, including: a chassis; a wheel carrier; a drive wheel; a steering motor for rotating the wheel carrier relative to the chassis; a reduction gear connecting the steering motor to the wheel carrier, the reduction gear including a planetary gear set including an internal sun gear, at least one planet gear, and a planet carrier on which the planet gear is mounted, a ring gear surrounding the internal sun gear and the planet gear. The shaft of the steering motor is fixed relative to the internal sun gear, the wheel carrier is fixed relative to either the planet carrier or the ring gear, and the chassis is fixed relative to the other one of the two components.
