Split type three-phase fixed seat structure of three-in-one electric drive system

Abstract

The invention discloses a split type three-phase fixed base structure of a three-in-one electric drive system. The split type three-phase fixed base structure comprises a three-phase copper bar, a three-phase fixed base, a common mode magnetic ring and a three-phase fixed base tail cover, wherein each phase of copper bar of the three-phase copper bar has a power module mounting hole position, a copper bar mounting hole position and a motor winding terminal mounting hole position; an epoxy glue pouring groove, a common-mode magnetic ring placing groove, a three-phase fixing base tail cover placing groove, a three-phase copper bar placing groove are formed in the three-phase fixing base, and a threaded insert is arranged on the three-phase fixing base corresponding to the copper bar mountinghole position; the three-phase copper bar is inserted from the epoxy glue pouring groove and enters the three-phase copper bar placing groove; and epoxy glue is injected into the epoxy glue pouring groove after the three-phase copper bar is preassembled. The complexity of the die and the die cost are reduced, the consistency of the product size is improved, the product cost is greatly reduced, the relative sealing of the motor and the motor controller is ensured, and meanwhile, the stable and reliable working environment of the motor controller is ensured.

Description

technical field [0001] The invention belongs to the field of three-phase fixed seats, and relates to a split-type three-phase fixed seat structure of a three-in-one electric drive system. Background technique [0002] With the development of new energy vehicle technology, the electric drive system presents a development trend of high integration and miniaturization. The motor controller is one of the core components of the electric drive system, and the motor controller is the key component of various structural parts and electrical devices. Combination, complex operating conditions. The three-phase fixing seat inside the motor controller is an important structural part of the electric drive system of electric vehicles, and is used for fixing three-phase copper bars and three-phase wiring harnesses. With the development of new energy electric drive assembly products, there are more stringent design requirements for the three-phase fixing seat connecting the motor and the mo...
