Motor controller

Abstract

The invention discloses a motor controller, which comprises an upper cover and a housing, wherein the housing and the upper cover are fixedly connected through a bolt. A high-voltage direct-current plug-in is inserted into the outer part of the housing; and the housing is internally equipped with a positive conductive copper bar, a negative conductive copper bar, at least one filtering unit, a capacitor, an IGBT module and an integrated circuit board, wherein one end of the positive conductive copper bar and one end of the negative conductive copper bar are connected with the high-voltage direct-current plug-in, and the other ends pass through a filtering unit and are connected with the capacitor; the capacitor is connected with an IGBT module; the circuit board is pressed on the IGBT module; three-phase output terminals of the IGBT module are respectively and correspondingly connected with three current sensors integrated on the circuit board; each current sensor is connected with a copper bar; and the tail ends of the copper bar extend out of the bottom surface of the housing to form three-phase output wiring terminals of the controller to be connected with three-phase wiring terminals of the motor. The structure of the controller is optimally designed, so that the overall size of the controller assembly is reduced, and whole vehicle installation and arrangement is convenient.

Description

technical field [0001] The present invention relates to the technical field of motor control, and more specifically, relates to a motor controller. Background technique [0002] With the continuous upgrading and development of new energy vehicle drive systems, the lightweight, miniaturized, and integrated design of motor controllers has become a consensus in the industry, but now the integrated products developed by most domestic manufacturers are mainly in the simple physical stack Type integration, the motor controller and the motor system failed to share water channels and junction boxes, etc., and the volume of the controller is generally 6-8L, which failed to further miniaturize and integrate. Contents of the invention [0003] The purpose of the present invention is to address the shortcomings of the above-mentioned prior art and provide a motor controller for an integrated electric drive assembly. By optimizing the structure of the controller, the overall volume of ...
