ELECTRIC MOTOR WITH HEAT DISSIPATION FOR THE MOTOR SHAFT BEARING

The invention relates to an electric motor comprising a motor casing (2) which has a shaft portion for accommodating a motor shaft (4), and a motor portion for accommodating motor electronics (5) and motor windings (6), the shaft portion and the motor portion being separated from each other in a sealed manner by a can (7) that is arranged in the motor casing (2). The can (7) is equipped with a metal ball bearing pot (8) in which a ball bearing (9) for mounting the motor shaft (4) is secured, and indirectly via the can (7), the ball bearing pot (8) adjoins, with an intermediate gap, a casing cover (3) that forms part of the motor casing (2), such that the casing cover (3) acts as a heat sink and heat generated by the ball bearing (9) during operation is dissipated onto the casing cover and into the outer surroundings via the ball bearing pot (8) and the can (7). 本发明涉及一种具有马达壳体(2)的电动马达，所述马达壳体具有用于容置马达轴(4)的轴部以及用于容置马达电子组件(5)和马达绕组(6)的马达部，其中所述轴部和所述马达部被布置在所述马达壳体(2)中的屏蔽套(7)密封隔开，其中在所述屏蔽套(7)中设有金属质的滚珠轴承套(8)，用于支承所述马达轴(4)的滚
