Abstract
A special three-phase asynchronous motor for automobile is composed of a stator, a rotor and a coil. The motor has phases Y, Q and Z, and adopts Y connection mode, has the hybrid ratio of single-dual layer of 1:2:1, is provided with 4 poles and 36 slots and 4 parallel branches; when the motor requires the power of 5.5kW, 1-10 inserted wires are in span, the number of turns of coil is 3, 2-9 inserted wires are in span, the number of turns of coil is 6. The special three-phase asynchronous motor for automobile low noise, small vibration and overcomes the resonance phenomena during frequency conversion, and has the advantages of low harmonic wave content, small loss, low temperature rise, high conversion efficiency, low manufacturing cost, reliable use, simple and convenient maintenance, energy saving and practical properties.
Description
Technical field:
The utility model relates to electric automobile, particularly relates to the automobile specified threephase asynchronous machine.
Background technology:
The driven by power car is the main vehicles that vehicle is come at end, the world, is Green Product, and car, minicar all can use.In world developed country has been a kind of trend, and domestic automobile producer is in recent years also all at the exploitation electric automobile of falling over each other, the special product on the electrocar that the special-purpose traction motor of low-voltage variable frequency three-phase car is present domestic production.It divides brush direct current machine and brush-less permanent magnetic direct current machine, and its defective is that electric efficiency is low, maintenance workload is big, expense is high, poor reliability, and advanced automobile making state is all being changed to alternating current machine by direct current machine.
Summary of the invention:
The purpose of this utility model will provide a kind of automobile specified threephase asynchronous machine exactly, and it can overcome the existing problem of above product well.The purpose of this utility model is achieved in that the automobile specified threephase asynchronous machine, is made up of stator, rotor, coil, it is characterized in that: YQZ type motor is a three-phase, and Y connection, single two-layer hybrid are 1: 2: 1,4 utmost points, 36 grooves, 4 parallel branches; When power of motor needs 5.5KW, 1-10 rule span, coil is 3 circles, 2-9 rule span, coil is 6 circles.The utlity model has noise low, the vibration little, overcome the covibration in the conversion process, harmonic content is low, loss is little, temperature rise is low, conversion efficiency is high, cost is low, use is reliable, maintenance is simple and convenient, energy-conservation practical characteristics.
Description of drawings:
Fig. 1 is the utility model boarding line loop graph;
1. the coil that is the 1-2 groove connects, and 2.U1 is an A phase head, 3. represents the head of a utmost point winding, and 4.V2 is a B phase tail, and 5.W1 is a C phase head, the 6. tail and the outlet of a utmost point winding of expression, and the thick line between the 7.1-10 is represented the rule span.8. be that 4 parallel branch 9.W2 are C phase tail, 10.V1 is a B phase head, and 11.U2 is an A phase tail, and on behalf of stator core, 12.1-36 36 grooves are arranged.
Embodiment:
The automobile specified threephase asynchronous machine is made up of stator, rotor, coil, it is characterized in that: YQZ type motor is a three-phase, and Y connection, single two-layer hybrid are 1: 2: 1,4 utmost points, 36 grooves, 4 parallel branches; When power of motor needs 5.5KW, 1-10 rule span, coil is 3 circles, 2-9 rule span, coil is 6 circles.The utility model adopts voltage 32V speed-regulating range width, and 0.52Hz can start to 133Hz, and peak power is up to 20KW, is 4 times of rated power.By the 48V storage battery power supply, controller adopts the vector control method of Speedless sensor, accepts gear signal by the LIN communication, accepts the electric brake pedal signal and realizes the energy feedback.
