  • Patent number: 11742715
    Abstract: A motor housing (2) has a shaft section to receive a motor shaft (4) and a motor section to receive motor electronics (5) and motor windings (6). The shaft section and the motor section are separated from each other in a sealed manner by a separating pot (7) arranged in the motor housing (2). A metal ball bearing pot (8) with a ball bearing (9) is arranged in the separating pot. The ball bearing pot (8) lies indirectly against a motor housing section that is connected to the outer surroundings, via the separating pot (7). Thus, the motor housing functions as a cooling body. Accordingly, heat generated by the ball bearing (9) during operation is dissipated onto the motor housing and the outer surroundings, via the ball bearing pot (8) and the separating pot (7).
