Abstract: 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.

Abstract: An electromechanical assembly including an electric machine coupled to a reducing gear, the electric machine including two bearings or rollers, the reducing gear including two bearings or rollers, the reducing gear and the electric machine each including a housing including means for attachment to the other housing, the electric machine and the reducing gear each including a shaft engaged in the other, each shaft including centring projections produced in such a way that the mutual engagement of the shafts has a centring effect that positions the housings correctly in order for them to be attached by means of the attachment means.

Abstract: In a high-voltage transformer for the power supply of a magnetron in a microwave oven, of the type comprising a primary coil, a high-voltage secondary coil and a heater secondary coil, the two secondary coils are superimposed by being wound on a casing that comprises three parallel flanges, two flanges for the winding of the high-voltage coil and one additional flange which, with one of the preceding flanges, enables the winding of the heater coil.
