Abstract

The invention provides a connection and conversion mechanism for a translation type motor three-phase winding and belongs to the technical field of electric automobile motors. The connection and conversion mechanism is characterized by comprising a set of fixed wiring assembly and two sets of movable wiring assemblies. Under the driving effect of a driving mechanism, only one set of the two sets of movable wiring assemblies is in short-circuit connection with the fixed wiring assembly. The fixed wiring assembly and the movable wiring assemblies are used for connecting two different windings of a motor. The fixed wiring assembly comprises a first upper-edge wiring terminal and a first lower-edge wiring terminal. A first movable wiring assembly comprises a second upper-edge wiring terminal and a second lower-edge wiring terminal, wherein the second upper-edge wiring terminal and the second lower-edge wiring terminal are respectively and correspondingly in short-circuit connection with the first upper-edge wiring terminal and the first lower-edge wiring terminal of the fixed wiring terminal. A second movable wiring assembly comprises a second upper-edge wiring terminal correspondingly in short-circuit connection with the first lower-edge wiring terminal. The connection and conversion mechanism for the translation type motor three-phase winding changes the torque constants of a motor, so that the switching between the large torque and the high rotating-speed of an electric automobile in different road conditions can be realized.

Description

technical field [0001] The utility model relates to a translational motor three-phase winding connection conversion mechanism, which belongs to the technical field of electric vehicle motors. Background technique [0002] Electric vehicles are a new means of transportation in recent years, and are welcomed by more and more families for their advantages of energy saving and environmental protection. The car needs to adapt to various road conditions when driving. When the electric car climbs a hill, the electric motor in the electric car needs several times the overload torque to provide enough power; while the electric car needs a high speed when the road is flat. However, because the motor torque constant of the general motor is fixed and cannot be changed, it is difficult to meet these two requirements at the same time, and the high speed can only be achieved by motor field weakening control, which sacrifices the efficiency of the motor accordingly. [0003] Therefore, in ...
