Definitions
- the invention relates to an electric motor according to the preamble of claim 1.
- the professional world has been concerned with the accommodation of electrical components in or on the housing of a motor or generator for a long time.
- the document DE 101 .23 626 AI shows a converter for electrical machines, a capacitor surrounding the machine being present, to the electrodes of which the bridge circuits are connected distributed over the circumference of the machine.
- the aim of the invention is to simplify the production process and to achieve space-saving arrangement.
- This solution was used among others in the case of a starter generator which had to be accommodated between a transmission and an internal combustion engine, the motor cross section being many times larger than the motor length.
- the disadvantage of the arrangement is that the capacitor surrounds the machine and thus significantly affects the dimensions of the cross section.
- a receiving device for the motor condition detection comprises at least one component of the motor supply.
- ⁇ t. , ⁇ It can be, for example, an electrical or electromechanical component or device.
- the motor supply takes over the control of the motor windings with currents of suitable voltage and frequency, while the motor condition detection acquires information about the characteristic motor data during operation by means of suitable sensors.
- the electrical component can be any electrical components of apparatuses which are encompassed by or arranged in the vicinity of the motor housing.
- the dimensions of the outer contours of the overall arrangement are determined by the motor housing itself, the receptacle for the motor condition detection and a suitable housing for the motor supply.
- This housing can be arranged on the circumference of the motor housing (joint use of the motor housing for heat dissipation) or axially (on the B side).
- the storage space already present in the housing of the motor condition detection is now used by including at least one electrical component of the motor supply. There are hardly any additional costs and the implementation effort is limited, since only a stable accommodation of the components and contact must be guaranteed.
- the additional volume required to accommodate the engine supply is reduced.
- the edge length of a motor with integrated power electronics is hardly much longer than that of a standard motor.
- the motor housing itself expediently serves as a recording device for the motor condition detection, in that it is dimensioned in such a way that it also accommodates the stator and rotor.
- the advantage that results from this can be seen in a dense and connectionless implementation that includes all components equally completely.
- the receiving device is a separate housing, which is combined with the motor housing.
- This additional housing could, for example, be flanged to the B side of the motor housing, whereby it should adapt to the outer contours of the motor and thus only change the length but not the cross section. Defective components or a complete engine condition detection can be quickly replaced.
- the components are expediently formed from at least one annular and / or cylindrical and / or rectangular body.
- the component could at least partially include the engine status detection within the housing. This ensures easy accommodation with optimal space utilization. But even with rectangular or cylindrical shapes, an optimal space can be obtained.
- Such components are generally also much cheaper to manufacture than the ring-shaped, which saves material but is much more expensive.
- a suitable arrangement of individual components of various designs could make even better use of the available space.
- the component with at least one connection for connecting a plug or a socket is encompassed by a frame designed as a common support, the frame having a coaxial recess, then this frame can be used for the generally cylindrical motor condition detection within the housing
- the coaxial recess serves as Recess for the spatial placement of the engine condition detection within the frame depth.
- the connection can serve, on the one hand, to connect the motor windings to a multi-phase power supply supplied by a converter or inverter, and can include the connections for the motor condition detection and a detachable connection for the component.
- the frame can serve as insulation from the generally grounded housing, provided that it is made of a non-conductive material, such as plastic.
- the lines required for interconnecting the components can also be easily fixed using guides attached to the frame.
- the frame is expediently provided with a plate whose profile is identical to the cross section of the housing of the motor feeder.
- the plate then also serves as a cover for the housing of the motor feed. If this cover is still provided with a seal, then high requirements for the degree of protection of the device can also be met.
- the frame as such therefore fulfills a multiple function, namely that of insulation, a holding device, a cable guide and a tight cover.
- the component is advantageously arranged in a V-shape on the frame.
- This arrangement ensures a small footprint, because the space between the motor condition detection and the housing inner wall is used optimally.
- a U-shaped arrangement of three or more capacitors would also be conceivable.
- a rectangular, frame-like arrangement around the engine condition detection is favored.
- the frame is formed by block capacitors.
- Motor housing attached and thus fully integrated with the motor includes motor converter or motor inverter and the component
- DC link capacitance of the DC link But others nearby too Control devices installed in the motor could use the space available for their components (e.g. inductors, line filters, Y-capacitors and similar voluminous or heavy components).
- Energy is supplied to the converter by means of a DC link: the DC link capacitance is used for buffering and especially for smoothing the DC link voltage, which was generated by rectifying the phases of a three-phase network and contains harmonic components.
- the inductance of the intermediate circuit has an effect such that voltage peaks can destroy the IGBTs in the integrated converter. It is therefore necessary to place an appropriately dimensioned capacitance on the converter as close as possible because it has little induction.
- This capacitance which can be realized, for example, by means of one or more electrolytic capacitors, sometimes has considerable dimensions, depending on the dimension, and accordingly requires a lot of storage space.
- the invention provides this storage space without increasing the outer contour of the motor.
- the service life of the DC link separator also depends heavily on the ambient temperature to which it is exposed. Mounting the housing near the motor condition detection, away from the motor windings, which are sometimes very hot during operation, increases the service life.
- a feedback device could, for example, be one that works using optical methods Be a facility that could work according to the multi-turn principle, for example. Such devices are often associated with
- Asynchronous machines / synchronous machines are used, which are controlled in three phases by means of drive controllers via an intermediate circuit and inverters. These are preferably used to drive servo axes and. Main spindle drives. Often, very strict requirements apply to the dimensions, since such generators / motors in turn have to be accommodated in machines that also have very high requirements with regard to the dimensions (machine tools, automation lines, printing machines, etc.).
- the component could advantageously be a line reactor or a line filter, because these components are usually very voluminous and accordingly take up a lot of storage space, which would have to be created additionally.
- FIGS. 1 to 3 show the receiving device 1, the capacitance 2, the motor housing 3 and the motor condition detection 4 or the space 4a provided for this and the output 5 and the interface 6.
- the receiving device 1 shown open is B -. flanged on the side of the motor housing 3.
- the flanging creates the seam 6, which can be sealed against external influences by means of a suitable device. It would also be feasible to extend the motor housing so that the interface 6 is omitted and hermetic partitioning of the inner components is easier to implement.
- the motor shaft acting as output 5 is shown on the A side. Due to the lack of coverage of the receiving device 1, an insight into the interior is possible.
- the round or square (FIG. 2/3) capacitors 2 or a single ring capacitor 2 (FIG. 1) required to realize a desired capacitance can be seen.
- the space 4a (FIG. 2) takes the often circular and cylindrical engine condition detection 4 ( Figure 1/3).
- the optical sensors of the motor condition detection are operatively connected to the motor shaft 5 and record values such as speed, acceleration and position.
- the space occupied by the capacitors 2 would be unused without considering the invention.
- the invention enables sensible use of space without changing the external dimensions of the overall arrangement 1 and 3.
- the ring capacitor 2 according to FIG. 1 ensures a complete utilization of the free space around the engine condition detection.
- the ring formed from cylindrical individual capacitors 2 in FIG. 2 ensures a similarly effective use of space and can be realized much more economically.
- the rectangular outline of the motor condition detection shown in FIG. 3 is realized by means of inexpensive block capacitors 2 and makes optimal use of the space between the outer walls of the housing 1 and the motor condition detection 4 right into the corners of the housing.
- any desired capacitor shapes could also be combined with one another. So the space between the block 2 and the capacitors for example, could engine state detecting arranged yet by means of a ring or by means of capacitor annular> single cylindrical capacitors 4 are used (Fig. 3). Small cylindrical individual capacitors would also have to be accommodated in the corners of the housing.
- FIG. 4 shows the concrete realization of a frame-shaped carrier with fastening bores 11.
- the carrier 7 itself and recesses 8, 9 and 10 are shown.
- the recess 8 serves to receive a plug or a coupling in order to be able to releasably connect the intermediate circuit capacitance to the direct voltage intermediate circuit.
- the V-shaped capacitor recesses 9 ensure effective use of space.
- the frame shown in FIG. 4 is dimensioned such that it can hold two foil capacitors connected in parallel with a total capacitance of around 24 ⁇ F. Both capacitors are dimensioned in such a way that the arrangement, depending on the permanent inverter output and the maximum permissible voltage drop in the event of a brief overload or in normal operation, still delivers good curing results. Of course, any interconnections of capacitors (parallel connection / series connection) are conceivable. This configuration is used for a synchronous machine with a maximum speed of around 3000 rpm with a torque of approx. 6 Nm and a permissible peak effective current of around 15 amperes per phase.
