The invention belongs to the field of electric propulsion system motor driving, and particularly relates to a motor and controller integrated device for eVTOL. Comprising an integrated heat dissipation fan assembly, a motor assembly and a controller assembly, a motor and controller integrated heat dissipation scheme is adopted, forced air cooling heat dissipation is conducted on the controller through a motor integrated fan, the design of a cooling system is simplified, and the power-to-weight ratio is effectively increased. And meanwhile, the motor controller and the motor adopt coaxial equal-outer-diameter design, and the characteristics of high power density and high volume density are very suitable for being applied to an eVTOL aircraft electric propulsion system.
