It is that current people apply most power power-equipments, in the prior art, the electricity of motor in industrial production and life activity
Power supply mainly can be accessed by brush, the contact by brush with commutator, and make to be electrically connected between brush and commutator
Conducting truncation between frequent transitions, electric energy is sent into armature, makes the continually changing magnetic field of armature, the continually changing magnetic field with
Stator interaction, to drive rotor rotation band dynamic load.As shown in Figure 1, the internal structure of existing motor is usually coaxial
Formula rotation radially contacts with commutation, i.e. brush central axis is overlapped with commutator radial direction, using the motor of this structure type,
Since the contact area between brush and commutator is small, when they connect, conductive reliability is poor, and when larger by electric current
When, since contact area is small, it is easy to produce spark, and noise is larger when motor operation, phone quick abrasion affects motor
Service life, and for electric machine manufacturer, the embedding and welding procedure of armature are also relatively complicated, increase manufacture at
This.

The brush central axis intersects vertically with the commutator radial direction.
The motor with novel commutating structure further includes casing, brush box and spring, and the stator and casing, which are fixed, to be connected
It connects, the rotor is installed within casing, and brush box is fixed together with casing, and the brush is contained within brush box, bullet
One end of spring is connect with the brush, and the other end of spring is connect with brush box inner wall.
The spring is cylindroid helical-coil compression spring.
It include copper in the making material of the brush.
It include graphite powder in the making material of the commutator.
The rotor is armature, and the stator is magnet steel.
The stator is coaxial with the rotor suit.
The beneficial effects of the present invention are: use technical solution of the present invention, by by brush relative between commutator
Connection contact be changed to axially contact mode, i.e. brush central axis intersects vertically with commutator radial direction, make brush and
Contact area between commutator increases, and the flowable conductive cross-sectional area of electric energy is bigger, to improve commutation reliability, subtracts
The noise in motor operation is lacked, in addition, brush is installed within brush box by compressed spring, under spring force, has made
Brush contacts closely with commutator, further improves commutation reliability, and the axially mounted brush in this outer makes in motor case
Each component in portion is easier to arrange closely, so that motor case inner space is made effective use of, and brush passes through by motor
