Abstract

In an electric motor, one one bearing plate (4) is made of plastic. A heat dissipation plate (9) is arranged a short distance in front of that side of the bearing plate (4) which faces the interior of the electric motor. The heat dissipation plate (9) carries heat from a bearing (5) to an electric motor housing (6), which is made of metal. This allows the electric motor to be manufactured particularly cost-effectively.
