Description
Technical field
The present invention relates to a kind of series excitation type motor, finger is applied to the series excitation type motor in the field of dynamic power machine especially.
Background technology
In modern production, motor (Electric Motor) is used in the various fields on the dynamic power machine at large with its easy and effective characteristic.Motor promptly is the motor that industrial quarters was commonly called as.If classify, then can be divided into two kinds of d.c. motor and alternating current motors according to employed power type.The operation principles that it is basic mainly is to utilize coil or armature are seated among the magnetic field, after this coil or armature are passed to an electric current, makes this coil or armature become electromagnet, and produces magnetic pole.Utilize the homopolarity mutual exclusion of magnetic pole, the principle that heteropole is inhaled mutually makes this coil or armature and this magnetic field produce electromagnetic induction, and thereby form an electromagnetic force torque, impel a rotating shaft that is connected in this coil or armature to rotate.In addition, also can utilize a commutator (being commonly called as commutator) to change this sense of current that inputs in this coil or the armature, so that this electromagnetic force torque can allow this rotating shaft keep running with the direction of original rotation, make the ability that possesses continuous drive machinery production and work.Therefore, motor or motor promptly are a kind of machines that converts electric energy to mechanical energy.
If do further to distinguish, then motor (or motor) can be done how different classification with different modes such as control, startup or coilings.For example, classify, just can be divided into two kinds of magneto and excitation types according to the generation type in its magnetic field.Wherein, the magnetic field of permanent-magnet motor is produced by a permanent magnet, it is characterized in that this magnetic field is a fixing magnetic field, can not change because of the variation of exterior magnetic field.So, the excitation type motor then is that portion utilizes the mode of serial or parallel connection to add one group of magnetizing coil in addition within it, and the magnetic field of motor running itself can be provided by the principle generation of electromagnetic induction.Series excitation type motor promptly is topmost a kind of in this class excitation type motor.
Seeing also Fig. 1, is the structural map of a known series excitation type motor 1.By as can be known shown in Figure 1, this known series excitation type motor 1 is by a stator modules 10, a rotor module 20, an end points carriage group 30 and organize brush module 40 more and formed.
Wherein, this stator modules 10 includes a casing 11, a magnetic field winding 12 and a casing wiring 13.This rotor module 20 includes a rotating shaft 21, a commutator 22 and an armature winding 23.This end points carriage group 30 includes a forward terminal carriage 31, an aft terminal carriage 32, one preceding insulation external member 310 and a back insulation external member 320.Arbitrary brush module as in these many group brush modules 40 mainly all includes a brush 41 and a brush electric wire 42.In addition, this stator modules 10 mainly be by this casing wiring 13 introduce an external impressed current to this magnetic field winding 12 producing magnetic field, and can with the combination that fixes of this end points carriage group 30 so that can support the rotation of this rotor module 20.Again, this rotor module 20 is arranged among this casing 11 of this stator modules 10, and this commutator 22 and these armature winding 23 tandem arrangements are on this rotating shaft 21.Wherein, these rotating shaft 21 activities are sleeved on 310,320 li of this forward and backward insulation external members in this forward and backward end points carriage 31,32.
On the other hand, this brush 41 in should many group brush modules 40 just by this forward terminal carriage 31 by overlaying on this commutator 22, after utilizing this brush electric wire 42 to introduce another external impressed current, electric power just can reach on this armature winding 23 via this commutator 22, make that this armature winding 23 can be in the middle of the magnetic field that this magnetic field winding 12 is produced, in response to producing an electromagnetic force torque, and and then drive this rotating shaft 21 and rotate.
So-called known series excitation type motor 1 is the meaning that this armature winding 23 (or practise claim rotor coil) is connected with this magnetic field winding 12 (or practising the operating coils that claims) work and getting.As for this commutator 22, then can in position the electric current that inputs to this armature winding 23 be changed direction, make this electromagnetic force torque can allow this rotating shaft 21 be rotated further with the direction of original rotation.Usually than compact motor or motor, be to be this armature winding 23 with coiled by enamelled wire, relatively large motor or motor then are directly to adopt the winding that is shaped to be used as this armature winding 23.
Again, by as can be known shown in Figure 1, each brush module 40 also comprises a slot 43, and this brush 41 promptly is sleeved among this slot 43 in the mode of activity, and is inserted in accordingly among this forward terminal carriage 31.In addition, a spring 44 can flexibly be pushed this brush 41 on this commutator 22 to, makes that this brush 41 can be by overlaying on this commutator 22.Because a junction 45 is electrically connected between described brush 41 and this brush electric wire 42, so by this connecting portion 45, just this another external impressed current can be introduced among the described brush 41, and and then this another external impressed current be sent on this commutator 22 and this armature winding 23 by this brush 41.
In general, the kind of described brush 41 can be divided into: charcoal quality brush, electrical equipment blacklead (being graphite) brush, pitch coke are brush, blacklead system and metal blacklead matter brush or the like.Because this rotor module 20 is among the process of high speed rotating, can cause described brush 41 and this commutator 22 between the fierceness friction, therefore, be subjected to the materials influence of described brush 41 itself, can make this friction process cause high heat, high temperature easily, produce spark even.If the ability of its Nai Gaore high temperature of material of this known series excitation type motor 1 integral body is lower, or this known series excitation type motor 1 itself can not effective inhibition because the measure of the friction spark that produces, might cause electrical equipment to cock off, or even cause the danger peace incident that fire etc. is great accidentally.
