    The invention relates to an electric machine, in particular for driving a vehicle, which is electrically connected to at least one adjacent electrical power supply device.
    DE 100 11 591 A1 describes a rotary motor with a rotor and a stator, wherein fuel cells are arranged as an internal energy source in a ring shape in the stator about the axis of rotation of the motor.
    From US 5,923,106 A an electric motor with integrated fuel cells is known, wherein the fuel cells are arranged within a cylindrical stator which is surrounded by a rotor of the electric motor. A similar electric machine is also known from US 6,005,322 A.
    In conventional electrically driven vehicles, such as electric vehicles or hybrid vehicles, the electric motors are spatially separated from batteries installed in the vehicle. This has the disadvantage that additional space in the vehicle for the accommodation of the batteries must be provided and that high-voltage power lines between the electric motor and the batteries must be installed in the vehicle, which represents a significant security risk, especially in an accident.
    The object of the invention is to avoid these disadvantages and to save in a battery-powered electric machine space for the arrangement of the batteries and to increase security.
    According to the invention, this is achieved by virtue of the fact that at least one electrical energy store forming the electrical energy supply device adjoins the electrical machine, wherein preferably the electric machine is surrounded at least partially, preferably entirely, by at least one electrical energy store.
    It when the electrical energy storage and the electric machine are arranged in a common outer housing is particularly advantageous.
    The one or more electrical energy storage can surround the electric machine annular. The electrical energy storage can have an axis 2, which is parallel to that of the electric machine, but also have a perpendicular to the axis of the electric machine aligned axis. Alternatively, it is also possible that the electrical energy store is arranged within a rotor surrounding the stator.
    The electrical energy store can thus be integrated into the stator of the electric machine.
    The fact that the electrical machine and the one or more electrical energy storage is formed as a unit, parts can be saved, and the production and assembly work can be substantially simplified.
    It is particularly advantageous if the electrical accumulator is arranged in a cavity spanned between an inner housing surrounding the electrical machine and an outer housing. The outer housing may have the shape of a circular cylinder or a prism, preferably a cuboid.
    In order to allow sufficient heat dissipation during charging and discharging of the electrical energy storage, it is provided that at least one cooling device is provided for cooling the electrical storage. It is advantageous if a cooling space is formed between at least two electrical energy storage devices, wherein a cooling space is preferably formed between the inner housing and the outer housing. In particular, in liquid cooling, the outer housing may have connections for the inlet and outlet of the coolant.
    The cooling circuit of the electric machine can be carried out together with the cooling circuit for the energy storage, but it can also be provided separate cooling circuits.
    In the context of the invention can be provided that the electrical energy storage is formed by individual substantially cylindrical batteries, wherein preferably the batteries are arranged in a tightest packing. Alternatively, the energy storage may be block-shaped, welded into bags or be integrated directly into the structure of a housing. 3
    In a further embodiment of the invention it is provided that power electronics and / or a battery control is arranged on or within the outer housing, wherein preferably the power connections to the electric machine and the electrical energy storage are arranged within the outer housing. In this way, all power lines outside the outer housing can be avoided.
    The combination of the electric machine, the power electronics and the energy storage can thus account for high voltage cables in the vehicle. This results in a much lower security risk. Since power electronics and electrical energy storage no longer need to be accommodated in the vehicle, space can be saved significantly. The short high voltage connections within the unit improve the electromagnetic compatibility (EMC). In addition, sources of error such as plugs and cables can be avoided.
    The invention will be explained in more detail below with reference to FIGS.
    1 shows an electrical machine according to the invention in a sectional oblique view, and FIG. 2 shows this electrical machine in a cross section.
    The figures show an electrical machine 1 with a rotor 2 and a surrounding stator 3, wherein the stator 3 is surrounded by an inner housing wall 4. Around the inner housing 4 of the electric machine 1, electric energy accumulators 6 formed by rechargeable batteries 5 are arranged in a cylindrical cavity 8 formed by the inner housing wall 4 and an outer housing wall 7 of a housing 11. The substantially cylindrical batteries 5 are annularly arranged in the densest packing in two rows, between the batteries 5 and the housing walls 4, 7 cooling chambers 9 are formed. Furthermore, cooling channels can also be arranged in the housing walls 4, 7.
    The outer housing wall 7 has in Fig. 1 substantially in the shape of a cylinder.
    Alternatively, the outer housing wall 7 but also have the shape of a prism, in particular a cuboid, as indicated in Fig. 2 by dashed lines 4. Again, the individual batteries are arranged next to each other in close packing.
    The electric machine 1 and the electrical energy storage 6 formed by individual batteries 5 is formed as a unit, wherein all the high voltage lines are arranged within the outer housing wall 7. As can be seen in FIG. 2, a power electronics 10 and / or a battery control can also be integrated into the outer housing wall 7 or placed on the outer housing wall 7.
    The power connections to the electric machine 1 and the electrical energy storage 6 may be located within the housing 11 of the unit 12. By combining the electric machine 1, the power electronics 10 and the electrical energy storage 6 can - when used for an electrically powered vehicle - the high voltage power lines in the vehicle accounts. This results in a low safety risk, for example in the event of an accident. The short high voltage connections within the housing 11 increase the electromagnetic compatibility. Error sources such as plugs and cables can be largely avoided or significantly reduced.
    The unit 12 of electrical machine 1, electrical energy storage 6 and power electronics 10 can be installed in a hybrid vehicle between an internal combustion engine directly to a crankshaft or between an internal combustion engine and a drive motor. Furthermore, an attachment on or after the transmission output is possible.
    The unit 12 can be carried out both uncooled, as well as cooled. In the case of liquid cooling, the cooling can be integrated in the cooling system of the internal combustion engine, or be designed as a separate cooling circuit for the electric machine 1 and the electric energy storage 6.
    The electric machine 1 may be both an external rotor, or an internal rotor. Of the type, the electric machine can be designed as a synchronous motor, as an asynchronous motor, as a permanent-foreign-excited machine, as a reluctance machine or as a DC machine.
    The housing 11 may be made of either metal or plastic. 5
    The unit 12 is designed as a closed, fully functional, autonomous module. The fact that external space for the battery 5 and the power electronics, as well as external cooling lines and power lines can be omitted, can also be significantly reduced in weight and components.
    The axial extent of the unit 12 is determined by the required power.
