Abstract
The utility model relates to a kind of novel wound stators of electric vehicle brushless motor, including stator core, tooth, slot and coil；The stator core is ring structure, tooth of the internal perisporium along its circumferentially uniformly distributed multiple protrusion；It is slot between the tooth and tooth；The coil is divided into three-phase, and in 120 degree of distributions, the beginning and end of every phase coil is distributed the starting point of three-phase coil in 180 degree；Every winding coil from a slot penetrate after along clockwise direction continuously around two adjacent teeth, form two continuous windings in starting point；It is in be entered by the slot in front of the tooth, be pierced by after two adjacent teeth including the tooth along clockwise direction at another tooth of 180 degree with the tooth of the first winding of starting point that coiling, which is cross over, forms the windings of two connections in terminal；Each phase coil carries out three with wye connection and is connected.
Description
Technical field
The utility model relates to motor fields, and in particular to a kind of novel wound stator of electric vehicle brushless motor.
Background technique
Stator is one of main working parts of motor, and currently used stator winding generally uses short span coiling, three
Mutually work matching conversion two-by-two, low speed is started to walk, and stability is poor, and motor working efficiency is lower.
Utility model content
In order to solve the above-mentioned technical problem, it is fixed to provide a kind of novel winding of electric vehicle brushless motor for the utility model
Son.
The technical solution adopted in the utility model is: a kind of novel wound stator of electric vehicle brushless motor, including stator
Iron core, tooth, slot and coil；The stator core is ring structure, tooth of the internal perisporium along its circumferentially uniformly distributed multiple protrusion；It is described
It is slot between tooth and tooth；The coil is divided into three-phase, and the starting point of three-phase coil is in 120 degree of distributions, the starting point of every phase coil and end
Point is distributed in 180 degree；Every winding coil from a slot penetrate after along clockwise direction continuously around two adjacent teeth, playing a dot
At two continuous windings；It is at another tooth of 180 degree, by the slot in front of the tooth with the tooth of the first winding of starting point that coiling, which is cross over,
Enter, be pierced by after two adjacent teeth including the tooth along clockwise direction, forms the windings of two connections in terminal；Each phase line
Circle carries out three with wye connection and is connected.
The number of the slot is set as 3 even-multiple.
The number of the slot is 12.
The coil also being capable of wrapped anti-clockwise.
The beneficial effects of the utility model are: the utility model improves the winding mode of the short span of existing product, with
Winding distribution is carried out to the large span across 180 °.It matches controller appropriate and completes three-phase synchronous conversion, improve the low speed of motor
The stability that starts to walk and the working efficiency for promoting motor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, I, stator core, II, slot, III, coil.
Specific embodiment
As shown in Figure 1, the utility model includes stator core I, slot II and coil III.Wherein, slot II is arranged 12, coil
III is set as A, B, C three-phase.Wherein for A phase using A1 as starting point, A2 is terminal, enters 2 groups of continuous windings by 2 slots and enters 3 slots and 4
Then slot directly enters 8 slots and 10 slots into 2 groups of continuous windings to being cross over 9 slots, by 10 slot outlets.
For B phase using B1 as starting point, B2 is terminal, enters 2 groups of continuous windings by 6 slots and enters 7 slots and 8 slots, directly to being cross over 1 slot
Enter 12 slots and 2 slots into 2 groups of continuous windings, by 2 slot outlets.
For C phase using C1 as starting point, C2 is terminal, enters 2 groups of continuous windings by 10 slots and enters 11 slots and 12 slots, directly to being cross over
5 slots enter 2 groups of continuous windings and enter 4 slots and 6 slots, by 6 slot outlets.
Coil is connected after the completion with wye connection progress three.Also opposite direction winding may be implemented.
