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 fluid moving apparatus includes an electric motor having a rotor and a stator and a propeller. The rotor rotates relative to the stator on an axis to generate a rotational output. The rotational output is provided to the propeller to power the marine propulsion apparatus. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the axis. A portion of a housing of the motor extends into the aquatic environment to facilitate heat dissipation.

A method for controlling a synchronous double stator electric machine. A first stator and a first set of magnetic poles on a common rotor forms a first electric machine. A second stator and a second set of magnetic poles on the rotor forms a second electric machine. The first electric machine and the second electric machine is shifted mechanically by a predetermined angle. An electrical shift is produced to the control of at least the mechanically shifted electric machine with a respective frequency converter in order to at least partly compensate for the mechanical shift in the mechanically shifted electric machine.
