Embodiment Construction

[0033] Embodiments of the present invention will be described based on the drawings.

[0034] In addition, in the following description, "axial direction" means the direction of the central axis of a stator, a rotor, or a drive shaft. In addition, "radial direction" means the direction orthogonal to the said axial direction.

[0035] figure 1 An example of the outer rotor type motor of the present invention is shown.

[0036] This outer rotor type motor 1 is configured to include: a plurality of stators 10 aligned in the axial direction; a rotor 20 supported to rotate around the plurality of stators 10 ; and a drive shaft integrally provided with the rotor 20 30; the winding coil 11 wound on each stator 10; the magnet 21 fixed on the rotor 20 corresponding to each stator 10; the above-mentioned plurality of stators are fixedly supported from one end side in the axial direction as a non-rotatable fixed The supporting member 40; and the rotating supporting member 50 that rota...

Abstract

[Problem] To provide an outer rotor motor configured so that the lead wires of the winding coils for the stators are routed simply. [Solution] An outer rotor motor is provided with stators (10) arranged in the axial direction, a rotor (20) supported so as to rotate around the stators (10), a drive shaft (30) provided integrally with the rotor (20), winding coils (11) respectively wound on the stators (10), and magnets (21) affixed to the rotor (20) so as to respectively correspond to the stators (10). The outer rotor motor is configured so that the rotor (20) and the drive shaft (30) are rotated by the magnetic action between the winding coils (11) and the magnets (21). A through section (10b) extending in the axial direction is provided in at least one of the stators (10), and the lead wires (11a1, 11a2) of the winding coils (11) are inserted through the through section (10b) and led to the outside.

Description

technical field [0001] The present invention relates to an outer rotor type motor in which a rotor rotates on the outer peripheral side of a stator, and particularly relates to an outer rotor type motor preferably used as a prime mover of a small electric aircraft or the like. Background technique [0002] Conventionally, in such an invention, for example, as described in Patent Document 1, there is a brushless motor comprising: a drive shaft (2); a plurality of stators (15, 16) disposed on the outer periphery of the drive shaft; drive wheels (21), the central part is fixed on the outer periphery of the above-mentioned driving shaft and protrudes radially toward the above-mentioned driving shaft; a plurality of cylindrical rotors (26, 27) are respectively fixed on the outer peripheral part of the above-mentioned driving wheel, and respectively extend from the above-mentioned driving wheel extend and protrude concentrically with the drive shaft on both sides in the direction ...
