Definitions
- the invention is based on an electrical
- Commutator machine according to the preamble of claim 1, 5 or from the use of a contact tab of an electrical commutator machine according to claim 12.
- a stamped and bent part is produced and has at least one tab for attachment to an insulating material pane, as well as further tabs which serve as cooling fins.
- the tabs for fastening are passed through holes in the insulating pane, then bent around the insulating pane and thus pressed onto the insulating pane. In the case of high shaking stresses, this can lead to the loosening of the brush holder on the insulating cloth, a brush guided in a brush holder then no longer being able to attack a commutator of an electrical machine in the desired manner.
- the brush is connected to an electrically conductive strand, the strand generally in an additional Welding fork or guide is arranged so that the strand does not vibrate too much under high shaking stresses.
- the electrical commutator machine according to the invention or the use according to the invention of an electrical contact tab of a brush holder with the characterizing features of claims 1 or 5 or 12 have the advantage that the resistance to shaking of an electrical commutator machine is improved in a simple manner.
- a brush wire or a suppressor choke is advantageously used as the electrical functional element, which can be connected directly to the brush holder, so that no further connecting elements are necessary.
- An electrically conductive carrier is advantageously fastened to a base carrier consisting of non-electrically conductive material, the tab for fastening the brush holder to the carrier, for example, advantageously being welded or soldered and thus connected in a shake-proof manner.
- a base support of a brush holder made of non-electrically conductive material can have a metallic coating in places, on which then advantageously and way the tab is welded or soldered for fastening and is thus connected to be shake-proof.
- the carrier is arranged shake-proof, for example, by plastic injection molding on the base carrier.
- FIG. 2a shows a brush holder with brush for a commutator machine designed according to the invention
- FIG. 2b shows a further embodiment of a brush holder with brush for a commutator machine designed according to the invention
- FIG. 3a shows a carrier which is connected to the brush holder
- FIG. 3b shows the arrangement of the brush holder with holder according to FIG. 3a in a brush holder for a commutator machine designed according to the invention
- FIG. 4 a brush holder for a commutator machine designed according to the invention.
- FIG. 1 shows an example of the structure of an electrical commutator machine 1, which is an electrical motor or an electrical generator, for example.
- the electric motor can be used for an electric actuator, for example.
- the electrical commutator machine 1 consists of at least one stator, for example a Magnetic yoke element 4, for example formed by a pole tube with a bearing plate, and has at least one magnet 5.
- the magnets 5 are arranged on the inside of the magnetic yoke element 4.
- a rotor 8 rotating within the stator consists, for example, of a laminated core with an electrical winding, the laminated core being fastened to a rotor shaft 11. Parts of the winding are electrically connected to a commutator 18.
- Brushes 20 engage the commutator 18 and conduct an electrical current from the outside to the commutator 18.
- the brush 20 is guided in a brush holder 17.
- the at least one brush holder 17 is arranged, for example, on a brush holder 14.
- the brush holder 17 can also be arranged on the end shield, for example.
- FIG. 2a shows a brush holder 17 which has been manufactured, for example, as a stamped and bent part and has at least one tab 26 for fastening.
- the tab 26 engages, for example, the brush holder 14 (not shown), so that the brush holder 17 is attached to the brush holder 14. This takes place, for example, in that the tabs 26 are guided through a correspondingly shaped opening on the brush holder 14 and are then bent over.
- a brush strand 29 is connected to the brush 20 and conducts the electric current into the brush 20.
- the other end of the short brush wire 29 is electrically and mechanically firmly connected by means of an electrical connection 35 to a contact tab 32 of the brush holder 17.
- This short brush wire 29 has a high resistance to shaking due to its short length and does not have to be guided or held.
- the brush wire 29 forms an electrical functional element of the electrical commutator machine 1, since the electrical current flows through it.
- FIG. 2b shows a further embodiment of a brush holder 17 of an electrical commutator machine 1 designed according to the invention.
- the brush holder 17 of FIG. 2b has a second contact tab 32, on which, for example, a suppressor choke 38, as an electrical functional element of the electrical Commutator machine 1, is connected. Additional connection elements between suppressor choke 38 and brush wire 29 can therefore be omitted.
- Figure 3a shows a brush holder 17 and a carrier 41.
- the carrier 41 has three tabs. Two of these tabs form carrier attachment tabs 47 and a third tab forms a carrier contact tab 53
- Carrier mounting tabs 47 are with the tabs 26 of the
- Brush holder 17 connected, for example by soldering or welding, thereby creating a shake-proof mechanical and electrical connection between the carrier 41 and the brush holder
- the carrier 41 and the brush holder 17 can also be made in one piece.
- FIG. 3b shows how the brush holder 17 with the carrier 41 attached to it is arranged on a brush holder 14.
- the brush holder 14 consists at least of a base support 44 made of electrically non-conductive material, for example Plastic or ceramic.
- the carrier 41 is for example encapsulated by the plastic of the base carrier 44 and is thus arranged on the base carrier 44. Other types of attachment of the carrier 41 to the base carrier 44 are possible.
- the carrier 41 can only be partially recognized, since the plastic of the
- Base carrier 44 partially surrounds the carrier 41.
- the contour of the carrier 41 is indicated by dashed lines.
- the three tabs 47, 53 of the carrier 41 protrude on one side of the, for example, annular base carrier 44.
- An electrical interference suppressor 38 is connected to the carrier contact tab 53, for example, as an electrical functional element. Since the carrier 41 is made of metal, for example, an electrical connection is established between the interference suppressor 38 and the brush holder 17.
- the electrical current for driving the commutator machine 1 flows, for example, via a suppressor 38, via the carrier contact plate 53, via the carrier 41 to the brush holder 17, to which a brush strand 29 is fastened on a contact plate 32 (FIG. 2), which supplies the current to the brush 20 forwards.
- the brush holder 17 can also after the plastic injection molding around the carrier 41
- Carrier mounting tabs 47 are attached.
- FIG. 4 shows a further exemplary embodiment of a brush holder 14 for an electrical commutator machine 1.
- the base carrier 44 does not have a carrier 41, but only protrusions 50, which are coated, for example, with metal, so that the tabs 26 of the brush holder 17 are welded to the coated protrusions 50 or can be soldered.
- protrusions 50 which are coated, for example, with metal, so that the tabs 26 of the brush holder 17 are welded to the coated protrusions 50 or can be soldered.
- soldering or welding the tabs 26 to the elements 47, 50 fixedly arranged on the base support 44 a shake-proof attachment of the brush holder 17 to the base support 44 of a brush holder 14 is possible.
