ELECTRIC DRIVE SYSTEM AND DESIGN METHOD THEREFOR

WIPO Patent Application WO/2024/032723

A1

The present invention provides an electric drive system and a design method therefor. The electric drive system comprises at least one axial magnetic field motor and at least one speed reducer, wherein one axial side of the axial magnetic field motor is provided with an output end face. The design method comprises the following steps: (a) carrying out design according to the radial dimension of the axial magnetic field motor and the transmission ratio required by the electric drive system, so to obtain the speed reducer; and (b) connecting the output end face of the axial magnetic field motor to the side of the speed reducer facing away from the wheels, so to obtain the electric drive system. Taking advantage of the axial magnetic field motor having a small axial dimension and a large radial dimension, the design space utilization of the speed reducer can be further increased, and two such axial magnetic field motors and two such speed reducers can be arranged between the two wheels.
