Novel modular motor controller

Abstract

The invention relates to the technical field of motor controllers, in particular to a novel modular motor controller, comprising a film capacitor, an IGBT module, a driving circuit board and a controlcircuit board, wherein the film capacitor comprises a housing and a capacitor main body fixed at the inner bottom of the housing, a plurality of cooling water inlet pipe columns, a plurality of cooling water outlet pipe columns and a plurality of IGBT connecting columns are further arranged at the bottom of the housing, upper end pipe orifices of the cooling water inlet pipe columns and the cooling water outlet pipe columns extend out from heat conduction packaging and filling rubber blocks to respectively communicate with an IGBT water inlet and an IGBT water outlet of the IGBT module, lowerends of the cooling water inlet pipe columns and the cooling water outlet pipe columns respectively communicate with a water inlet and a water outlet on the housing, the upper ends of the IGBT connecting columns extend out from the heat conduction packaging and filling rubber blocks, and the IGBT module is detachably connected with the IGBT connecting columns through connecting rods; and throughthe design of the modular motor controller, the film capacitor is cooled very well, true water cooling is achieved, and the film capacitor cannot be easily damaged.

Description

technical field [0001] The invention relates to the technical field of motor controllers, in particular to a novel modular motor controller. Background technique [0002] Motor controllers inevitably generate heat during their work. Therefore, it is necessary to conduct the heat to the outside in a timely and rapid manner through the heat dissipation structure; otherwise, the functions of the related electronic components of the controller will be affected, and even the related electronic components of the controller will be burned, eventually causing the motor to fail to work, so the heat dissipation performance of the controller Good or bad is directly related to the service life of the controller. [0003] Limited by material cost and material characteristics, the current temperature resistance of film capacitors can only reach 105°C, and the temperature resistance of other components inside the motor controller can reach 125°C. Film capacitors have now become the shorte...
