Abstract
Disclosed is a commutator (20) for an electric motor (10), comprising lamellae (22, 24), contact bridges (30) via which lamellae (22, 24) having the same electrical potential are interconnected, and contacts (26) that are disposed on lamellae (22) and are used for connecting wires (18) of the armature winding. Only every other lamella (22) is provided with a hook (26) for the wires (18) of the armature winding, thus creating more space for winding the wire (18).
Description
The present invention is based on the commutator as described in the preamble of claim 1, for example as US6,057,626 is disclosed such.This commutator that is used for electric notor comprises that commutator segment is located at being used on the commutator segment and is connected the contact of armature winding lead with touching bridge and having, and is connected to each other with identical current potential by the described bridge commutator segment that touches.But the armature supply of generation of forced symmetry so perhaps also can reduce to two with the quantity of the brush of necessity.
Commutator according to the present invention with claim 1 characteristic features has following advantage, and promptly the distance between the hook of two direct neighbors has enlarged.There is more space to use like this, and therefore can increases the quantity of the commutator segment and the armature slot of commutator for the lead contact.Armature supply that so also can the generation of forced symmetry, perhaps the quantity with the brush of necessity reduces to two.For this reason, the commutator that is used for electric notor has commutator segment, touch bridge and have and be located at contact on the commutator segment and lead that be used to connect armature winding, be connected to each other with identical current potential by the described bridge commutator segment that touches, wherein, not every commutator segment has the contact that is used for armature winding.Preferably commutator has n commutator segment and m contact, wherein, and m＜n.Commutator has n commutator segment and m contact, wherein m=n/x and wherein x＞1 in another favourable organization plan.In a preferred improvement project, only has a contact every a commutator segment.Specially suitable is the hook-type commutator, because it is more to leave the space that is used to twine lead for.Particularly in armature, can reach more groove number, can reduce the commutator bar-to-bar voltage thus, and therefore reduce the wearing and tearing of brush with more multipole number (more than 2).Therefore it is favourable designing a kind of armature that is used to have the motor of electric notor, and described electric notor has such armature.
Provide other advantage and favourable improvement project in dependent claims and the explanation.
An embodiment shown in the drawings, and in following explanation, this embodiment is narrated in more detail.
These accompanying drawings are:
Accompanying drawing 1: the longitudinal section of electric notor,
Accompanying drawing 2: the perspective view of the commutator of electric notor.
Accompanying drawing 1 is the longitudinal section sketch of electric notor 10.In automobile for example in glass regulator, in the windscreen-wiper drive, fan is medium all can use this electric notor.This electric notor 10 comprises 12, one armatures 14 that are provided with therein of a casing.Armature 14 has an axle 16 and the armature core 17 with the armature winding that is not shown specifically.Armature winding is connected with a commutator 20 by lead 18.
With reference to the accompanying drawings 2, commutator 20 is included in the equally distributed commutator segment 26 that has the commutator segment 22 of hook 24 and do not have hook on the circumference, and these commutator segments are fixed on the matrix 27.This matrix has a hole 28 that is used for axle 16.These hooks 24 are to be used for the contact that is connected with the lead 18 of armature winding.Replace hook 24 that other contact also can be set.What for example replace hook in so-called slot type commutator is a groove, and lead 18 is routed in this groove.Then groove is carried out interference fit.
Can be clear that commutator segment 26 is not used in the hook 24 of armature winding.Be provided with eight commutator segments 22,26 and four contacts.Only that is to say and have a contact every a commutator segment 24.Common statement is that n commutator segment and m contact are set, and wherein m＜n is provided with n commutator segment and m contact in other words, m=n/x wherein, wherein, x＞1.
Also to be provided with at last and touch bridge 30, touch bridge by these and have the commutator segment that hook 24 is arranged 22 of same potential and do not have the commutator segment 26 of hook 24 to be connected to each other.Only illustrate one for simplicity and touch bridge 30.Usually, the quantity of the quantity n of commutator segment and unshowned armature slot is the same.In a kind of four utmost point electric notors 10, between each two 180 ° opposed commutator segments 22,26, be provided with n/2 and touch bridge 30.The lead 18 of armature winding is with the contact on (in this situation directly opposed) hook 24 of identical current potential.Like this, at least two loops (Schlaufe) of lead 18 contact on this hook 24.For this reason, for example in the motor of one four utmost point, need design the quantity n of commutator segment according to n=(x * 4)+2, wherein, x=1,2,3 etc.Therefore a possible design variant scheme is a quadrupole motor 10 with the armature 14 that has 18 grooves and 18 commutator segments, wherein, has only 24 contacts of 9 hooks.Identical principle is applicable to the motor with higher number of poles.
