Embodiment Construction

[0016] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0017] Such as Figure 1-2 As shown, the device includes a motor controller 1 and a motor 2. A plurality of lugs 102 are provided around the bottom of the housing of the motor controller 1. Threaded holes 201 are drilled at the top of the motor 2 corresponding to the lugs 102. The motor controller 1 It is fixed on the top of the motor 2 by bolts passing through the lug 102 and the threaded hole 201 .

[0018] An insulating base 3 is provided on the top of the motor 2 , and a connecting copper bar 304 is pierced on the insulating base 3 . The insulating base 3 includes a copper bar fixing terminal 301 at the top, a fixing base 302 at the middle, and a copper bar covering part 303 at the bottom. The connecting copper bar 304 passes through the copper bar fixed end 301 , the fixed base 302 and the copper bar covering part 303 , and its lower end ...

Abstract

The invention belongs to the electric driving technical field and relates to a three-phase connection structure of an integrated controller electric driving system. The three-phase connection structure includes a motor and a motor controller fixed on the top of the motor; and the three-phase high-voltage power source output end of the motor controller is connected with the three-phase high-voltage power source input end of a motor through copper bars. According to the three-phase connection structure of the integrated controller electric driving system of the invention, an insulation base and copper bar connecting mode is adopted to replace a traditional three-phase high-voltage wire harness connection mode, and separate ribs are adopted to isolate the bar coppers at the top of the insulation base, and therefore, an occupied space can be decreased, and excellent insulation can be ensured, and the reliability of the driving system can be increased, and cost can be reduced; a wire outgoing box cover is adopted at the exterior of the insulation base to realize sealing; a sealing ring is arranged between the insulation base and the wire outgoing box cover, and therefore, the three-phase connection structure has excellent sealing performance; and components in the wire outgoing box cover are isolated from an external environment, so that the reliability of the power source connection between the motor controller and the motor can be further improved.

Description

technical field [0001] The invention relates to the field of electric drive technology, in particular to a three-phase connection structure of an integrated controller electric drive system. Background technique [0002] In the development of electric vehicles, the electric motor system has the characteristics of high power density and high efficiency. Motors and motor controllers are key components in electric vehicles. With the development of new energy vehicles, the requirements for power and reliability of motors and motor controllers are getting higher and higher. The traditional structural motor and motor controller use a three-phase wire harness to connect the high-voltage end, which takes up a lot of space, has high cost, and has low reliability. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a three-phase connection structure of an integrated controller electric drive system with small footprint, ...
