Background technique
Motor is a kind of energy conversion of mechanical energy that rotor rotation is converted electrical energy into according to electromagnetic induction principle,
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.
