Embodiment Construction

[0022] In the following, like reference numerals are used to refer to like parts.

[0023] Such as figure 1 As shown, a small electric motor 1 according to the present invention is configured in the manner of a claw pole motor and includes a rotor 2, a stator 3, and a housing 4 which is firmly connected to the stator 3 and whose two ends pass through The corresponding housing cover 5 is axially closed. The stator 3 of the claw-pole motor 1 according to the invention comprises two stator coils 10 and 10 ′, which are endowed with a ring-like structure and arranged coaxially with the axis of rotation 7 of the rotor 2 . Each of the stator coils 10 and 10' is bonded to an associated pole tooth edge 11 and 11', respectively, and the stator coils 10 and 10' adjoin each other in the axial direction. Stator coils 10 and 10 ′ are surrounded on the outside by housing 4 . The rotor 2 of the claw pole motor 1 according to the invention consists essentially of a hollow cylindrical perma...

Abstract

The motor (1) has flexible conductor foil (14) with winding connection contacts, external connection contacts and conductor paths between both contacts. The conductor foil is formed as elongated strip with spaced-apart connection portions (16,16') having winding connection contacts contacting taps of stator windings (10,10'). The connection portions are arranged at different positions in motor axial direction for connecting stator windings. The connection portion and stator winding are arranged at different sides of pole tooth rims (11,11') and taps are made to pass through rim opening. An independent claim is included for small electric motor producing method.

Description

technical field [0001] The invention relates to a small electric motor and a method for manufacturing such a motor. In particular, the present invention relates to a claw pole motor. Background technique [0002] Many application fields of small electric motors require continuous improvement of the degree of miniaturization. Electric motors have to be constructed in increasingly reduced and compact dimensions in order to be suitable for applications (eg in medical engineering). This requires, inter alia, a space-saving construction of the motor housing as well as a smart and efficient layout and design of the individual motor components. An optimized layout of the electrical connections and conductor tracks in the motor itself becomes critical. [0003] It is generally known from the prior art that the electrical connections of the stator coils are led out of the motor housing in the form of twisted wires. DE 3639004 A1 further discloses a claw pole motor with two stator...
