Cooling structure integrated with electric motor and controller

A cooling structure integrated with an electric motor and a controller, the controller including a power module and a control module, the electric motor having a rotor and a stator, the cooling structure integrated with the electric motor and the controller comprising:

• a shell, shaped as a cylinder to sleeve the stator;
• and
• a rear water jacket, including at least one assembly hole, the at least one assembly hole being to allow at least one conductive pillar to penetrate through, the rear water jacket being mounted to an axial end of the shell, the rear water jacket being furnished with a plurality of rear water jacket waterways, wherein the stator electrically couples one end of the at least one conductive pillar, while another end of the at least one conductive pillar connects the power module.
