Abstract

Integrated drive and motor assemblies are described herein. An example integrated drive and motor assembly includes an electric motor having a winding that concentrically surrounds an input drive shaft, an inverter for delivering power to the electric motor, a gearbox assembly coupled to the input drive shaft and an output drive shaft, the gearbox assembly having a planetary gear that includes a plurality of helical gears that couple with the input drive shaft and a ring gear. The planetary gear also includes a carrier that is rotatably coupled to the plurality of helical gears and transfers rotational forces to the output drive shaft. The assembly includes a housing that encloses the electric motor, the gearbox assembly, and the output shaft in co-axial alignment with respect to a central axis.
