1. An electrical machine, comprising:
a housing;
a control unit located in the housing, the control unit configured to control the electrical machine to generate a rotating magnetic field,
wherein the housing has a housing cup that encloses a cavity, and has a housing cover,
wherein the electrical machine has an end plate,
wherein the end plate is accommodated in the housing cup and is connected in a thermally conductive manner to the housing cup,
wherein the electrical machine has a cooling plate that is connected in a thermally conductive manner to the housing cup and to at least one component, or a plurality of components, of the control unit,
wherein the electrical machine has an inverter comprising semiconductor switches,
the semiconductor switches are connected in a thermally conductive manner to the end plate,
wherein the end plate and the cooling plate enclose between them a portion of the cavity,
wherein the control unit and the inverter are accommodated in the portion of the cavity, and
wherein the cooling plate is shrink-fitted into the housing cup.
