Definitions
- the invention is based on a brushless, electrically commutated DC machine, in particular a DC motor, according to the preamble of patent claim 1.
- the electronic circuit breakers designed as transistors are in each winding phase. arranged in series with this on the high-voltage side of the winding phase.
- the circuit breakers are made up of one control stage for generating switching signals and one
- Logic stage for the logical application of the switching signals to the control unit comprising the circuit breakers successively connected to the mains DC voltage.
- Circuit breaker blocks fully or the circuit breaker becomes conductive and carries continuous current with or without residual resistance In the first case, the function of the DC machine is limited or no longer available, but this is not critical.
- the second case can create a dangerous situation insofar as the stator winding of the machine and the circuit breakers heat up and a fire can occur due to continuous current.
- the temperature-sensitive fuses sometimes present in the supply line to the machine cannot solve this problem, since these must be designed for a current that can also be greater than this continuous current.
- fuses due to their series scatter r, allow up to seven times their nominal current, so that there is a risk that the stator winding and / or the electrical
- the brushless DC machine according to the invention with the features of claim 1 has the advantage that the heating melts through the heating much faster than if it is only heated by the machine or motor current flowing through it. Another advantage is that in normal Operation of the fuse does not represent any additional resistance in the circuit due to the extremely low ohmic resistance of the fuse wire, which adversely affects the efficiency of the machine or motor.
- the heating current for the electrical heating of the fuse is conducted via the fuse wire itself.
- the current flow through the fuse wire increases by the pickling current required for heating, so that the melting temperature is reached much more quickly.
- the heating current is automatically switched off when the welding wire melts.
- a heating wire or a heating cartridge extends along the melting wire, which in series with an electronic switch which closes in the event of a fault
- Stator winding is connected in parallel.
- the electronic switch is advantageously controlled by the control unit for the electronic circuit breakers in the stator winding.
- the time from the occurrence of the fault to the activation of the fuse is further reduced by the fact that the control unit is designed so that in the event of a fault it sends a control signal to all circuit breakers which triggers their closing. As a result, the current flowing through the fuse wire is extremely increased and the melting temperature is reached in an extremely short time.
- a pyrotechnic detonator which can be ignited by heating and which is connected in a heat-conducting manner to the hot wire can be arranged on or near the fuse wire.
- the fuse wire is torn open and the machine is shut down.
- the heating current required for the detonator to respond can be designed to be much lower than the heating current for heating the fuse wire of the fuse.
- the power supply for the control unit between the fuse and the stator winding preferably before a smoothing capacitor, is tapped. This has the advantage that the power supply for the control unit is also switched off when the stator winding is separated from the DC voltage network by the appealing fuse.

- Fig. 2 shows a section of a fuse in
- Fig. 3 is the same representation as in Fig. 2 according to another embodiment of the
- Fig. 4 is a view of a ceramic body of the
- the electronically commutated, brushless DC motor shown in FIG. 1, as an exemplary embodiment for a general DC machine, is operated by means of a control unit 11 for electronic commutation on a DC voltage source 10.
- the DC motor shown here only with its stator winding 12 has one in a known manner Stator winding 12 receiving stator or stator and a rotating rotor or rotor in the stator with permanent magnet poles or, in the case of a so-called SR (Switch Reluctance) motor, with a slot-tooth geometry.
- the three-phase stator winding 12 in the exemplary embodiment has three winding phases 13 connected in a star, which are connected to the positive potential of the DC voltage network 10 via a lead 31.
- An electronic circuit breaker 15 is arranged between each winding phase 13 and the star point 14, which is connected via a return line 21 to the negative potential of the DC voltage network 10, that is to say on the low-voltage side of the stator winding 12.
- the circuit breakers 15 are preferably designed as field effect transistors, in particular as a MOS-FET, and are controlled by the control unit 11 in such a way that the winding phases 13 are consequently and successively connected to the DC voltage network 10.
- a smoothing capacitor 32 is connected in parallel with the series circuits comprising the phase of development 13 and the circuit breaker 15.
- a fault protection device in the form of an electrically heatable fuse 16 is arranged in the feed line 31 to the stator winding 12.
- the fuse 16 is ' designed so that in the event of a fault, for example in the event of a failure of one of the circuit breakers 15 arranged in the stator winding 12 on the "low side" or when the smoothing capacitor 32 breaks down, it is heated with a heating current which is the current in the feed line 31 leading fusible wire 17 quickly warms to its melting temperature.
- a heating wire 18 in the fuse 16 Provided, which extends along the fuse wire 17 and is preferably designed as a heating coil 19. The heating wire
- the heating coil 19 is connected in series with an electronic switch 20 at the output of the fuse 16 between the feed line 31 and the return line 21 and thus connected in parallel with the stator winding 12 with the line switch 15, so that when the electronic switch 20 closes the through the heating wire 18 or the heating coil
- the fuse wire 18 is additionally heated and thus reaches its melting temperature in a shorter time.
- a heating cartridge (not shown here) can also be used. Heating the fuse wire 17 can be used.
- the electronic switch 20 which is designed as a transistor, has to switch the high heating current, but is relatively cold at the switching moment and only needs to carry out the circuit once, so that it does not have to be designed as a power transistor.
- the electronic switch 20 is controlled by the control unit 11 in such a way that it receives a control signal causing it to close in the event of a fault.
- the control unit 11, whose power supply between the fuse 16 and the stator winding 12, preferably before the smoothing capacitor 32, is removed, monitors the winding phases 13 of the stator winding 12 for continuous current and detects a fault in the case of continuous current in one of the winding phases 13, after which the corresponding control signal to the electronic switch 20 is placed.
- the control unit can handle such a continuous current
- the control unit 11 recognize, for example, that the current in the return line 21 is monitored by the stator winding 12. A continuous current in one of the winding phases 13 is present when a current flows in the return line 21, although the control unit 11 controls all the circuit breakers 15 in the sense of a switch opening. A current flow through the defective smoothing capacitor 32 can also be recognized by the current monitoring in the return line 21. Furthermore, the control unit 11 is designed so that when the fault is detected, it sends a closing signal to all the circuit breakers 15, so that the current flowing through the fuse wire L7 becomes maximum and, by increasing it, contributes to additional heating of the contact wire 17. •
- Structural exemplary embodiments for the heatable fuse 16 are each shown schematically in section in FIGS. 2 and 3.
- the fuse wire 17 is embedded in a ceramic tube 22 and the heating wire 18 as a heating coil 19 on the

- the fuse wire 17 is clamped between two terminals 23, 24 which protrude from the protective housing 25.
- the positive potential of the DC voltage network 10 is to be connected to the connecting terminal 23, while the connecting terminal 24 with the stator winding
- the heating coil 19 is on the one hand electrically connected within the protective housing 25 to the connecting terminal 24 and, on the other hand, has a connecting lug 26 which is led out of the protective housing 25 and which is to be connected to the electronic switch 20.
- fuse wire 17 and heating coil 19 are each arranged in a bore 27 or 28 within a ceramic body 29.
- the two parallel bores 27, 28 are arranged closely adjacent in the ceramic body 29, so that only a thin partition 291 made of ceramic material remains between them.
- 4 shows the end view of the ceramic body 29 which is egg-shaped in cross section.
- the bores 27, 28 arranged close to one another have different diameters.
- the fuse wire 17 also connects the two connecting terminals 23, 24 led out of the ceramic body 29, and the heating coil 19 is connected on the one hand to the connecting terminal 24 and on the other hand via the connecting lug 26 led out of the ceramic body 29 to connect the electronic switch 20 in FIG. 1.
