Abstract
An electric motor, in particular an internal rotor motor, with a stator constructed from laminations and with a rotor arranged concentrically in the stator, with a housing surrounding the stator circumferentially, and with two housing caps for axially closing the housing at both ends and for accommodating and carrying a shaft of the rotor, wherein the laminations each have at least three crosspieces arranged on the circumference for creating at least one coolant channel between the stator and the housing, and wherein the at least one coolant channel can be bounded by the housing caps in a fluidtight manner.
