TECHNICAL FIELD
[0001] The utility model relates to the technical field of wire harness sheath, especially to a kind of flame-retardant wire harness sheath for new energy automobile. BACKGROUND
[0002] The main functions of flat wire harness in new energy vehicles are: 1) improving power density: flat wire harness can fill more copper wire than round wire harness, thereby increasing slot fill ratio. The improvement of slot fill ratio means that a stronger magnetic field can be generated in the same space, thereby improving the power density of the motor. This is very important for new energy vehicles, as it can output more power in the same or smaller volume and weight, meeting the demand of high-performance drive motor. 2) optimizing heat dissipation performance: the rectangular cross-section of flat wire harness allows for greater contact area between conductors and conductors, as well as between conductors and core slots, resulting in better heat conduction. 3) reducing volume and cost: due to the shorter end of flat wire harness, copper material can be saved, and resistance is reduced, improving the efficiency of the motor. 4) reducing electromagnetic noise: flat wire can provide better stiffness to the motor armature, suppressing armature noise, and can take a relatively small slot size, effectively reducing the cogging torque, further reducing the electromagnetic noise of the motor, and improving the NVH performance of the vehicle.
