Definitions

  • Electric motors are often adapted to their particular application.
  • these adjustments include different ones
  • circuit board (9) is designed as a plug connection. In this way, the circuit board (9) can be assembled by a simple joining process.
  • the plugging process is further facilitated if at least one for the electrical connection between the printed circuit board (9) and a guide plate (10 or 11)
  • Rotor axis arranged on substantially opposite sides of the brush support bar (7). In this way, a more optimal use of space is achieved.
  • the additional shaft (49) serves to accommodate an additional circuit board (50) which is equipped with a thermal protection element (48)
  • the additional shaft (49) can also be used to hold a wired one
  • the end shield (19) has a radially outwardly open recess (51) which can accommodate at least one connecting line (17) in the case of a radial cable outlet.
  • the motor current is conducted exclusively via the guide plates (10, 11) and not via the printed circuit board (9).
  • the circuit board (9) is not heated unnecessarily and the EMC behavior is improved.
  • Spring contacts 52d are soldered onto the circuit board and serve as contact points for guide plates and a ground contact.
  • a notch 42d is used to adapt to a receiving shaft of a brush support plate.
  • the baffles have flat contact surfaces as counter contacts (not shown).
  • FIG. 6 shows a fourth view of the brush support plate 7b, with a variant relating to the contacting of the circuit board 9b.
  • a brush 8b, baffles 10b with welding areas 16b, a receiving shaft 24b for the printed circuit board 9b, a central passage 35b and a ground contact 18b can also be seen.
  • An additional shaft 49b is only indicated as a dashed line.
  • 7 shows a first arrangement of a printed circuit board contact, with the printed circuit board 9 equipped with SMD components 41 and the guide plates 10, 11. The printed circuit board 9 is pressed into clamping contacts 14 of the guide plates 9. The connection of the
  • FIG. 11 shows a detailed view of housing bushings 20 in the end shield 19.
  • the guide plates 10 and 11 with the connection pins 15 can be seen inside the motor housing.
  • the connection pins 15 are aligned axially parallel, so that the connection lines can be mounted correspondingly parallel to the rotor axis.
  • FIGS. 12 and 13 show flexible connecting lines 17 with rubber grommets 44 and plug contacts 47.
  • the rubber grommets 44 are connected to the connecting lines 17 and the plug contacts 47 by a crimp connection.
  • Thermal protection element 48e is located on an additional circuit board 50e.
  • the two circuit boards are connected within the commutator motor.
  • SMD components 41e, brushes 8e, a commutator 3e and suppression chokes 12e are also designated.
