A stator arrangement for an electric engine having an inner rotor. The present invention furthermore relates to an electric engine for a charging device, in particular for an internal combustion engine or a fuel cell, having such a stator arrangement. The stator arrangement comprises an outer stator core with electrical windings, and a separate inner stator core, which is arranged inside the outer stator core and is designed to receive the rotor. The outer stator core defines a first inner diameter, which is dimensioned in such a way that a bearing unit of the electric engine can be guided through the outer stator core. An outer diameter of the inner stator core substantially corresponds to the first inner diameter, wherein the inner stator core is designed to extend a magnetic flux in the radial direction during operation. The invention furthermore relates to a method for producing the electric engine.

A method of manufacturing a motor case for an electric motor of an e-boosting device in which the motor case is received within an outer housing to cooperatively define a coolant jacket. The method includes forming a shell member. The method also includes overmolding a dam member to the shell member. The dam member projects from an outer surface of the shell member. The overmolding of the dam member includes forming a molded through-hole through the dam member. The dam member and the outer surface are configured to define a fluid boundary for a coolant of the coolant jacket when the motor case is received in the outer housing. The through-hole defines a passage for the coolant in the coolant jacket.
