摘要： A liquid-cooled electric motor with a motor shaft, with two bearing plates which are mounted on the end faces of the motor housing and which carry on each side at least one bearing, the motor shaft being mounted rotatably in the bearings, and with at least one rotating hydraulic pump, the drive shaft of which is connected to the motor shaft by way of a coupling and which is driven by the electric motor. The casing of the motor housing receives a cooling liquid, has an at least partially hollow design and forms a casing cavity. At least one connecting duct for the supply of cooling liquid from the casing cavity to the bearings for cooling and lubrication of the bearings is provided in each of the bearing plates and in that said flanged-on hydraulic pump is sealed off in a liquid-tight manner with respect to the bearing plate interiors.
