Controller integrated electric driving system

Abstract

The invention relates to the technical field of electric driving and specifically relates to a controller integrated electric driving system. The controller integrated electric driving system comprises a motor controller and a motor; a DC bus inlet socket for power input and a signal output socket for signal output are arranged on a housing of the motor controller; a motor resolver signal wiring harness connected with the signal output socket is arranged on the motor; a three-phase high-voltage power output end of the motor controller is connected with a three-phase high-voltage power input end of the motor; the bottom of the housing of the motor controller is in threaded connection with the top of the motor; suspension mounting points connected with a vehicle body are arranged on the motor. The motor controller is fixed on the top of the motor by use of a bolt, and a set of suspension mounting points for installation with the vehicle body is arranged on the motor, and therefore, the occupied space of the driving system is greatly saved; a copper bar is adopted to take the place of a traditional three-phase high-voltage wiring harness for connection, and therefore, the occupied space is further saved; meanwhile, the reliability of the driving system is improved and the cost is reduced.

Description

technical field [0001] The invention relates to the field of electric drive technology, in particular to 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 are split structures, which are arranged separately in the vehicle, which requires a large installation space and complicated wiring harness connections. Due to the limited layout space of the vehicle, the volume of the motor system cannot be enlarged, and the output of the motor system The power is small and cannot better meet the power requirements of the vehicle. At the same time, traditio...

Problems solved by technology

The traditional structural motor and motor controller are split structures, which are arranged separately in the vehicle, which requires a large installation space and complicated wiring harness connections. Due to the limited layout space of the vehicle, the volume of the motor system cannot be enlarged, and the output of the motor system The power is small and cannot better meet the power requirements of the vehicle

At the same time, the traditional motor and motor controller need a three-phase wire harness to connect the high voltage end, occupying a large space, and the reliability cannot be guaranteed
