Abstract

The invention discloses a busbar of a flat wire motor, which comprises a first-phase busbar, a second-phase busbar and a third-phase busbar, and is characterized in that the first-phase busbar, the second-phase busbar and the third-phase busbar respectively comprise a main body part, and a first wiring part and a second wiring part which are respectively positioned on two sides of the main body part; the first wiring part is connected with a first outgoing line conductor located at the outermost corresponding phase of the stator winding, and the second wiring part is connected with a second outgoing line conductor located at the innermost corresponding phase of the stator winding; and one or two of the main body parts of the first-phase busbar, the second-phase busbar and the third-phase busbar are arranged between the first outgoing line conductor and the second outgoing line conductor. The invention solves the problem that the busbar is difficult to arrange due to the fact that the internal space of a winding of an existing flat wire motor is small.

Description

technical field [0001] The present application relates to the field of design and manufacture of automobile drive motors, in particular to a bus bar of a flat wire motor and a flat wire motor. Background technique [0002] With the development of the new energy automobile industry, the development of its drive motors also tends to develop in the direction of high voltage, high speed, integration, platformization, and miniaturization. Among them, miniaturization will inevitably require a significant increase in the power density of the motor. Flat wire motors That is, the flat copper wire is used in the stator winding. First, the winding is made into a shape similar to a hairpin, penetrated into the stator slot, and then the end of the hairpin is welded at the other end. Flat wire is conducive to the improvement of motor slot fill rate. Generally, the slot fill rate of round wire motor is about 40%, while the slot fill rate of flat wire motor can reach more than 60%. The imp...
