Abstract
The invention discloses a motor stator for an electrombile and a half-turn winding method of a motor stator winding. An armature part comprises a winding and an iron core, wherein the winding is formed by a plurality of coils; the coils are wound on the iron core teeth of the iron core; an iron core slot is arranged between the adjacent iron core teeth; the coils are embedded in the iron core slot; and the number of turns of the coil is 2n+1/2, wherein n is a positive integer. When the winding is wound, a turn coil is wound on the first iron core tooth of a first phase; then, the coil of the first phase and other coils of other phases are successively coiled until half bridging lines of the coil are positioned on the other side of the winding; and an outgoing line and an incoming line are positioned in the same slot. According to the motor stator and the method, revolving speed specification can be increased by one time.
Description
Technical field
The invention belongs to the motor of electric motor car field, relate in particular to a kind of motor of electric motor car half turn winding.
Background technology
Driving motor of electric vehicle substantially all is a rare earth permanent magnetic brushless dc motor now, in order to satisfy the requirement of electric motor car client to speed, generally all is to adopt the method for adjusting the motor windings number of turn to adjust rotating speed of motor.But for the winding of the low number of turn, if adjust a circle, then motor speed differs very greatly different, and this does not satisfy user's requirement yet.
Usually direct current machine all has one " commutator ", and can only be installed in an end of winding, and two statures of each coil of winding will be received on the corresponding commutator segment, so coil must be whole numbers of turns (circle) number, as shown in Figure 3.Even common motor also substantially all is a winding under the branch spreading, all can only be integer number of turn winding.But the characteristics of this motor are not have " commutator ", and are the striding of coil (joint) apart from being a groove, and are to adopt manual method directly winding conducting wire to be gone in the electric machine iron core groove around (embedding).
Summary of the invention
The objective of the invention is to provide a kind of motor of electric motor car stator of the rotating speed specification that can double and the half turn winding method of winding thereof.
The present invention realizes that the technical scheme of above-mentioned purpose is, a kind of motor of electric motor car stator, armature portion comprises iron core and winding, described winding is made up of several coils, coil winding is on the core tooth of iron core, have core slots between the adjacent core tooth, coil embeds in the core slots, and its innovative point is: the number of turn of described coil is
Circle, wherein n is a positive integer.
A kind of half turn winding method of motor of electric motor car stator winding, its innovative point is: roll off the production line coiling on first core tooth of first phase since first core slots of first phase
The circle coil, then successively coiling first mutually and other other coils mutually, until finishing, wherein n is a positive integer.
The winding configuration that the present invention adopts above-mentioned " the half turn number of turn ", adjust rotating speed of motor, can accomplish between original adjacent rotating speed specification, to have increased a rotating speed specification, and can not produce the situation that motor speed differs greatly, the needs in market have been satisfied in realized the doubling requirement of rotating speed specification.
