Definitions

• the present invention relates to a double-rotor motor according to the preamble of claim 1.
• Cooling by convection or heat dissipation via the generator holder is usually insufficient.
• Object of the present invention is to provide a double rotor motor with a good heat dissipation, so that the engine can be designed for higher power.
• the invention proposes to solve the problem that either a targeted air flow over several air wings or fan is generated or in addition a water cooling is provided in the housing.
• Most effective are water channels, which comprise the coil and are connected to channels in the housing.
• the ventilation and water channels are particularly simple and inexpensive to implement when they are either poured into the support structures between the excitation coils or preferably injected.
• the support structure can be closed externally by means of a lid.
• the Hinckerkanal is connected to the return channel.
• This cover also advantageously increases the rigidity of the support structure and can optionally be reinforced with an external reinforcement, such as ribs or reinforcing elements.
• On the lid can be omitted if a U-shaped pipe or profile is poured or injected.
• the electrical control unit also requires good heat dissipation.
• the controller is connected to the cooled with water cooling housing, heat-conducting.
• Fig. 1 Shows the basic structure of the double rotor motor with air and water cooling
• Fig. 2 shows the yokes with excitation coils as well as integrated in the double T-beams water channels;
• Fig. 2a shows the inlet and outlet of the water channels
• Fig. 3 shows an extended T-beam structure with water channels at the top and bottom;
• FIG. 1 shows the basic structure of a double rotor motor with housing 1, bearing 10, rotor shaft 9, flange 8 and double rotor 2, which has permanent magnets 3.
• a support structure 6 is injected, which also surrounds yoke 4 and exciter coil 5.
• the support structure 6 extends in the radial and axial direction between each two adjacent yokes 4 and excitation coils 5 and is anchored in recesses of the housing 1. The anchoring occurs during the injection process, wherein the injection molding material pours into the recesses and around the yokes and excitation coils.
• FIGS. 2 and 3 Part of the section through the engine is shown in FIGS. 2 and 3.
• the coil 5 is connected in a known technique via coil wire 11 with a punched grid 12, to which all the coil wires are contacted.
• a connection pin leads to the PCB 17 of the ECU.
• the housing contains water channels, which are described in more detail below.
• FIG. 1 shows the air duct for cooling the exciter coil.
• Air flow L 1 is generated by a fan wheel 8 connected to the rotor 2, 2 a, 2 b, whose air flow is guided through recesses 7 and ribbing to increase the surface area, and cools the end face of the exciter coils 5.
• Two further air streams L2 and L3 are generated by wings 14 between the magnets 3 of the outer and inner rotor 2a, 2b and lead the cooling air at the outer poles 4a, 4b of the yokes 4 with underlying excitation coils 5 over.
• the heat of the associated with the housing 1 excitation coils 5 is discharged directly into the housing 1 and passed over the cooling water channel 25 to the outside. 5 heat is dissipated by the entire surface of the coil.
• the power unit of the engine ECU also requires cooling. It makes sense to use the water-cooled housing, in which preferably the power unit is screwed onto web 18 of the housing 1. This web is preferably located in the immediate vicinity of the cooler inlet channel.
• Figure 2 shows another very effective solution for heat dissipation.
• a water channel 20 is provided in the support structure 6 of the yokes 4, which supplies the water via 20a and discharges via 20b.
• the side view of this mecanicsforrn is shown in Figure 2a. It shows the inflow into the support structure 6, which is injected or cast directly into the housing 1.
• a lid 21 with seal 22 is to continue the cooling water in the adjacent support structure 6 .
• This cover 21 can also serve as an external reinforcement with additional structure for air cooling, corresponding to Figure 1.
• FIG. 3 shows a side view of the feed from the water channel 20 a and discharge in the channel 20 b.
• the housing 1 must have the housing parts 1 a and 1 b in two parts. Since pressurized water is used, the channels 20a, 20b must be sealed.
• the cover 21 is connected to the support structure 23 via rivet pins 27. Through the housing, the coil wires 11 are guided for connection to the stamped grid.
• a U-shaped tube 24 can be injected or poured into the support structures 6, 19 for the purpose of guiding water.
• This can also consist of a specially adapted to the carrier profile.
• the advantage of the tube is in addition to the saving of the lid is that no special measures to the encapsulation must be made to seal.
• 6b support structure with water channel top and bottom
