The invention relates to the technical field of electric power steering systems, in particular to a small-size dual-redundancy electric power steering motor controller structure which comprises a sealing cover cap, a ventilation valve, a connector assembly, a power connector connector assembly, a bendable PCBA board, a screw, a double-end screw, a magnet, a radiator and a six-phase motor. The control panel is fixed at the top of the double-end screw through a screw, the control panel and the power board are connected through a bendable PCB, the power board and the control panel are connected through a power connector connector, and the control panel is provided with a connector. Compared with the prior art, the small-size dual-redundancy electric power steering motor controller structure is designed, through the arrangement of the bendable PCBA board, the power board and the control board are separated and installed in the controller in parallel, the size of the motor controller is reduced, heat dissipation is easy, and the motor controller can be conveniently applied to a whole vehicle.
本发明涉及电动助力转向系统技术领域,具体地说是一种小尺寸双冗余电动助力转向电机控制器结构,包括密封罩盖、透气阀、接插件、功率接头接插件、可弯折PCBA板、螺钉、双头螺钉、磁铁、散热器、六相电机,控制板与功率板平行放置,控制板采用螺钉固定在双头螺钉的顶部,控制板与功率板之间采用可弯折PCB连接,功率板与控制板之间采用功率接头接插件连接,控制板上安装有接插件。本发明同现有技术相比,设计了小尺寸双冗余电动助力转向电机控制器结构,通过可弯折PCBA板的设置,将功率板与控制板分离并平行安装在控制器内,既减小了电机控制器尺寸,也易于散热,便于在整车上应用。
