Specific work process and operation principle are as follows:
From this area Conventional wisdom:The torque constant K of one motor is to be inversely proportional with its winding parallel circuitry number a
Relation, therefore this parallel-moving type motor three-phase windings connect switching mechanism in, by change the circuitry number of winding parallel come
Reach the torque constant for changing motor, i.e. electric automobile is connected the connected mode of motor winding using in parallel in flat pavement running
Connect to run at high speed, the connected mode of motor winding is switched to and is connected in series by electric automobile in climbing, in this case
The torque constant of motor is doubled, therefore in the case of motor controller exports same current, motor output is turned round
Square is doubled, so as to reach the effect of low-speed big.
For motor in electric automobile because voltage is all than relatively low, number of poles is relatively more, so circuitry number is general all more, with most simple
2 branch roads winding exemplified by be described in detail:
The winding in motor is connected into corresponding in switching mechanism connect with book parallel-moving type motor three-phase windings first
Line terminals are attached:A phase windings, B phase windings, C phase windings upper strata side simultaneously with the A terminals in top mover wire connecting portion 3,
A terminals, B terminals on the left of B terminals, C terminal and bottom mover in wire connecting portion 4 are connected with C terminal, A phase windings, B phase windings,
The lower floor side of C phase windings is connected with the A1 terminals in wire connecting portion 8 on the right side of the mover of bottom, B1 terminals, C1 terminals respectively.U phase windings,
The upper strata of V phase windings and W phase windings while and during lower floor respectively with stator on the left of U terminals, V terminals and W terminals in wire connecting portion 2 with
And U1 terminals, V1 terminals are connected with W1 terminals in wire connecting portion 7 on the right side of stator.After being completed according to above-mentioned mode of connection connection,
The connection of machine winding forms winding as shown in Fig. 2 because A1 terminals, B1 terminals, C1 terminals are by the short circuit of connection sheet 10
Common point.
When electric automobile is in flat pavement running, the current supply circuit of motor 13 is connected, electricity rotates on motor 13
(It is set to rotate forward)Drive threaded rod 1 to rotate afterwards, top mover terminal plate 6 and bottom mover terminal plate 11 are driven by threaded rod 1
Move down simultaneously, motor 13 stops operating after top mover terminal plate 6 and the contact of stator terminal block 12, as shown in Figure 3.
Now A phase windings, B phase windings, the upper strata side of C phase windings pass through corresponding copper bar 14 and U phase windings, V phase windings, W phases respectively
Lower floor's side short circuit of winding, winding forms connected mode as shown in Figure 4, under this mode of connection, as shown in figure 5, in electricity
It is the star-like connected mode of two groups of windings in series inside motivation, U terminals, V terminals and the W terminals on the left of stator in wire connecting portion 2 are
Three-phase alternating current electrical input.
When electric automobile is climbed, the current supply circuit of motor 13 is connected, control motor 13 inverts, and passes through spiral shell
Rasp bar 1 drives top mover terminal plate 6 and bottom mover terminal plate 11 to move up simultaneously, when bottom mover terminal plate 11 and stator connect
Motor 13 stops operating after line plate 12 contacts, as shown in Figure 6.Now the A phases on the left of the mover of bottom in wire connecting portion 4 around
Group, B phase windings, the upper strata side of C phase windings pass through corresponding copper bar 14 and U phase windings, V phases in wire connecting portion 2 on the left of stator respectively
The upper strata side short circuit of winding, W phase windings;A phase windings, B phase windings on the right side of the mover of bottom in wire connecting portion 8, the lower floor of C phase windings
While respectively by corresponding copper bar 14 and U phase windings, V phase windings, W phase windings lower floor while short circuit.
With reference to Fig. 7, in bottom, the lower surface of mover terminal plate 11 position corresponding with binding post offers neck, cuts
Face is set with to correspond to from bottom to top after a spring 16 for the top of the brush 15 of " convex " type to be loaded in corresponding neck.Each
The top of individual neck corresponds to offer a fairlead respectively, the upper end of brush 15 by after connecting bolt link post from
The extraction of bottom mover terminal plate 11 forms corresponding binding post.Because the aperture of fairlead is less than the diameter of neck, therefore
The upper end of brush 15 and spring 16 can be stuck in the upper surface of neck without being dropped out from the upper surface of bottom mover terminal plate 11.
The internal structure of top mover terminal plate 6 is identical with the internal structure of the bottom mover terminal plate 11 shown in Fig. 7, no longer superfluous herein
State.
By setting spring 16, brush 15 is close to corresponding copper bar 14 under the action of the spring 16, good so as to ensure that
Good electrical contact.And short circuit in motor between winding and copper bar 14 is realized by brush 15, therefore during switching
Be not in spark, avoid in the prior art by the forms such as relay switch winding when easily because generation spark the problem of,
Service life is substantially prolongs, while improves safety and reliability.
When top mover terminal plate 6 and bottom mover terminal plate 11 move up simultaneously, winding forms connection as shown in Figure 8
Mode, under this mode of connection, as shown in figure 9, U phase windings are in parallel with A phase windings, V phase windings are in parallel with B phase windings, W phases
Winding is in parallel with C phase windings, and uses star-like connected mode in motor interior, U terminals, V ends on the left of stator in wire connecting portion 2
A terminals, B terminals on the left of son and W terminals and bottom mover in wire connecting portion 4, C terminal input as three-phase alternating current simultaneously
End.
, can be by changing this parallel-moving type motor three-phase when the motor in electric automobile is the circuitry number of other quantity
Winding connects switching mechanism middle connecting terminal and the quantity of copper bar 14 reaches and above-mentioned course of work identical transition effect.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model
Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Protect scope.
