Background technology
The species of motor is varied, and to distinguish according to electric power system, mainly includes alternating current generator and direct current generator.Hand over
Stream motor is typically high-power industrial motor, for direct current generator, is then mainly used in small-power driving equipment, such as toy car etc..
Direct current generator adopt dc powered drive motors rotor rotate, motor internal include two pieces of permanent magnets being oppositely arranged,
Rotor coil in the middle of permanent magnet, is energized to this rotor coil, and rotor coil just rotates in the magnetic field that permanent magnet produces,
According to electromagnetic principles, in rotor coil rotary course, often turn over 180 °, the sense of current in coil needs to commutate, ability
Rotor coil is made continuously to rotate in the fixed magnetic field that permanent magnet produces, for generally realizing using brush structure.Brush master
Including the conducting strip of two pieces of arc-shapeds being oppositely arranged, each conducting strip connects an input electrode respectively, and described rotor coil
Two feeder ears rotate in the region being surrounded by described brush, synchronization, a feeder ear of coil is only and brush
One arc-shaped conductive film contacts, when rotor coil feeder ear goes to another arc-shaped conductive film from an arc-shaped conductive film,
Electric current in rotor coil is commutated, during this, the insulation that rotor coil feeder ear will be jumped between two arc-shaped conductive films
Region, this makes the electric current in rotor coil suddenly from rated current jump vanishing, then is rated current from zero transition, causes to turn
The rush of current of subcoil, this rush of current will have influence on the life-span of rotor coil.
For solving this problem, Chinese patent 201210214217.3 discloses a kind of Stable-type direct-current motor, including
The stator being made up of shell, permanent magnet；Also include the rotor coil that can rotate in described stator by rotating shaft；Also include and institute
State the brush matching in two coil power supply ends of rotor coil；Be serially connected with described rotor coil and described coil power supply end to
A few self-induction coil.This Stable-type direct-current motor can make the electric current in rotor coil put down in rotor coil commutation process
Steady transition, thus reduce the rush of current to rotor coil, to extend its service life.
But, this technical scheme is only applicable to the direct current generator of one group of coil, and present direct current generator has evolved to
Multigroup coil, such as by the program, then every group of coil power supply end concatenates at least one self-induction coil, then it will take big quantity space,
With plus trochiterian weight, waste power and increase cost.
Content of the invention
For the problems referred to above, the purpose of this utility model is to provide that a kind of anti-electromagnetic interference capability is strong, structure is simple, becomes
A kind of strong motor of this low anti-electromagnetic interference capability.
This utility model be employed technical scheme comprise that for achieving the above object：A kind of strong electricity of anti-electromagnetic interference capability
Machine, including by shell, rotor and stator, shell is provided with housing and end cap, and described end cap is provided with and penetrates connecing inside and outside end cap
Line terminals foot, is provided with brush slot, spring groove and inductance groove inside end cap, an Anti-interference inductor is placed in inductance groove and is serially connected with wiring
Between terminal supportor and spring, spring is placed in the brush acting in brushgear housing in spring groove.
It is provided with the brushgear housing being surrounded square tube type by U-shaped copper sheet groove and a copper sheet in described brush slot, and be fixed in end cap
Side, the side of brushgear housing is provided with spring avoiding hollow groove, and when spring is placed in spring groove, one end of spring peaks at brush along avoiding hollow groove
Rear end face.
Described spring is torsionspring, and the central authorities of spring groove are provided with a locating dowel, and torsionspring is placed in locating dowel fixed
Position.
Described spring is to be placed on end cap draw-in groove with the described inductance place of concatenation.
The beneficial effects of the utility model are：The strong motor of this kind of anti-electromagnetic interference capability operationally, works as rotor line
When commutation between brush in the coil power supply end of circle, due to disturbing the presence of inductance, the transition of electric current in rotor coil will be suppressed, from
And improve the ability of electromagnetism interference, meanwhile, inductance, spring, brush etc. are dexterously designed inside end cap, and with accommodating
The form of groove is fixed, and realizes that structure is simple, the purpose of low cost.
