Definitions
- the invention relates to rotary electrical machines, in particular electric motors, which are operated by means of a drive circuit.
- Rotary electric motors are often driven or operated by means of drive circuits.
- the drive circuits provide, for example as drive voltages, a pulse width modulated voltage or one or more phase voltages.
- the drive voltages are generally generated by means of a suitable driver circuit, such as an H-bridge circuit or a B6 circuit, as AC signals.
- the drive circuits are usually arranged as separate structures or as integrated units on the electric motor or separated therefrom.
- both lead frames and printed circuit boards are used, which are in communication with the motor terminals, which allow electrical contacting of the motor winding.
- the arrangement of the drive circuit to the motor usually requires special structural measures in order to avoid that the drive circuit is exposed to environmental influences.
- suitable housing and Enclosures should be provided with which the drive circuit to be protected.
- an arrangement comprising an electric machine having an inner stator and an outer rotor arranged coaxially with each other and a driving circuit connected to a winding of the inner stator to drive the outer rotor by driving the winding.
- the drive circuit is arranged in a recess of the inner stator.
- One idea of the invention is to provide a drive circuit for an electrical machine, in particular an electric motor, in a recess of the electric motor, in particular in the interior of a stator of an external rotor motor. This allows a space-saving accommodation of the driving Circuit and also a protection of the drive circuit from environmental influences. Furthermore, vibrations of the drive circuit are significantly reduced, since the drive circuit is arranged closer to the axis of rotation of the electric machine and thus influences caused by an unbalance vibration are reduced.
- the drive circuit may be connected to supply lines to receive a supply voltage and to provide an AC signal for application to the winding.
- the drive circuit may be formed on a carrier material which forms a curved printed circuit board.
- the support material should be curved or flexible designed to be able to adapt to a curvature of an inner wall of the recess in the electric motor and in particular to simplify the manufacture of such a motor assembly.
- the drive circuit may be formed on a flexible carrier material, so that the drive circuit is deformable so that it can be inserted into the recess in a deformed state.
- the carrier material of the drive circuit is designed to go back to an undeformed state after deformation, so that after inserting the drive circuit in the recess, this rests against an inner wall of the recess.
- an insulating element may be provided which is arranged between the drive circuit and an inner wall of the recess.
- an electrically insulating material may be applied to an inner wall of the recess.
- the recess can penetrate the inner stator in the axial direction.
- a method for producing the above arrangement is provided, wherein the drive circuit is inserted into the recess of the inner stator.
- the drive circuit can be deformed prior to insertion into the recess of the inner stator.
- the single figure shows a cross section through a motor assembly 1 with an external rotor electric motor 2 as an electric machine.
- the outer rotor electric motor 2 comprises an inner stator 3 and an outer rotor 4, which are arranged coaxially with respect to a motor shaft 1 1.
- the inner stator 3 is fixedly fixed while the outer rotor 4 is connected to the motor shaft 1 1 to drive them.
- the electric motor 2 shown is designed as a synchronous motor, wherein the inner stator 3 carries a stator winding 5, which is arranged around a magnetically active material 6.
- the outer surface of the magnetically active material 6 is substantially envelope-shaped with a circular cross section, so that the inner stator 3 forms a circular cylinder.
- the outer rotor 4 is arranged coaxially with the inner stator 3 rotatably.
- the external rotor 4 is provided with permanent magnets 8 as rotor poles, which are arranged on a coaxial circular cylindrical pole pot 9.
- the inner stator 3 further has a concentric, circular cylindrical recess 7, which forms a cavity in the inner stator 3.
- the recess 7 may be formed continuously in the inner stator 3, so that the inner stator 3 forms a hollow cylinder open on both sides. Alternatively, the recess 7 in the inner stator 3 form a hollow cylinder closed on one side.
- a drive circuit 10 is provided, which is formed on a substrate 1 1, which serves as a printed circuit board.
- electronic components 12 are provided for the realization of the drive circuit 10.
- the electronic components 12 may include all electronically active devices, such as power transistors, capacitors, inductors, and the like.
- one or more H- Bridges or in synchronous motors include a B6 inverter circuit to generate the motor currents.
- the carrier material 1 1 In order to arrange the drive circuit 10 in the recess 7 of the inner stator 3, it is expedient to provide the carrier material 1 1 with a curvature, so that it adapts to the outer contour of the recess 7. If the outer contour of the recess is cylindrical, it can be provided that the electronic components 12 then protrude inwards, for example, radially from the carrier material 11. In this way, the area on the substrate 1 1 for the arrangement of electronic components 12 can increase and gain space.
- the carrier material 1 1 of the drive circuit 10 may consist of identical or different material layers, preferably of polyimide or polyamide, epoxy or other materials or combinations thereof.
- the carrier material 1 1 may be flexible, so that a deformability of the drive circuit 1 1 is ensured.
- the carrier material 1 1 may be provided elastically.
- the carrier material 1 1 in the substrate 1 1 in addition to elastic and rigid portions, e.g. made of standard FR4 material, be possible, so that the carrier material 1 1 may be formed as a combination of printed circuit boards, punched grids and a flex foil.
- the deformability of the circuit boards formed from the carrier material 1 1 makes it possible to change the drive circuit 10 in its shape so that it can be introduced into the recess 7 of the inner stator 3 in a simple manner. Due to the deformability of the drive circuit 10, this can be easily bent and simply pushed into the cavity of the inner stator 3. Depending on the deformation that has been carried out, the deformed carrier material 1 1 attempts to retake its original shape and thus fits into the cavity of the inner stator 3. For example, the driving circuit 10 after its insertion with the side of the outer surface of the recess 7 abut, which is opposite to the side which is equipped with the electronic components 12.
- the inner surface of the cavity may be provided with an insulating body 13 of electrically insulating material.
- This insulating material may be a suitable coating on the lateral surface of the recess or an insulating sleeve in the inner stator 3, which is inserted into the recess 7 before insertion of the drive circuit 10.
- This insulating body 13 can also accommodate attachments as part of the drive circuit 10, such as connectors, shaft bearings, heatsink, electrical line elements and Greierloche that can be connected to the drive circuit 10.
- the Kunststoffierloche on the insulating body 13 can also be used to hook winding wires or make electrical contacts between windings and the drive circuit 10.
- a highly elastic, non-conductive gel can be introduced as soft potting, for example silicone, to encapsulate the drive circuit 10 hermetically in the inner stator 3 and to improve the heat dissipation.
- covers may be provided to close the recess 7 on one side or on two sides.
- one or both of the covers may be provided with a feed opening through which one or more of the supply lines are routed.
- a fixing of the drive circuit by means of holding elements, such as snap hooks, ribs and beads, by means of injection molding, can be made possible by clipping or buttoning in the insulating body 13.
