Motor controller and electric drive assembly

The utility model provides a motor controller and an electric drive assembly, and the motor controller comprises a controller box body, a three-phase copper bar, and a heat-conducting glue layer. Wherein the three-phase copper bar comprises a copper bar body, a part of the copper bar body penetrates through the controller box body and is exposed out of the controller box body, and the three-phase copper bar is used for being connected with an internal structure of the motor controller or being connected with a motor copper bar body outside the controller box body. The heat-conducting glue layer is at least arranged at the contact part of the controller box body and the copper bar body and is used for transmitting heat generated at the copper bar body or other parts to the controller box body through the heat-conducting glue layer when the motor controller works normally, so that the heat generated at the copper bar body or other parts can be transmitted to the controller box body under the condition that the
