The invention discloses an electric window wiper based on a permanent magnet brushless motor drive control system. The electric window wiper comprises a transmission mechanism, a permanent magnet brushless motor, a wiping arm and a wiping blade. The device further comprises a position sensor, a programmable driving controller and a washer. The programmable driving controller controls the permanent magnet brushless motor to drive the wiper arm and the wiper blade to stop running immediately or in a delayed manner when the wiper arm and the wiper blade reach the absolute position of the position sensor according to the instruction; the washer comprises a washing pump and a liquid level sensor, and the programmable driving controller can read a liquid level signal returned by the liquid level sensor to control the washing pump to work or stop working. According to the programmable driving control system driven by the permanent magnet brushless motor, the basic wiping function is achieved by driving the torque output of the motor to push the wiping arm to swing, multi-thread and multi-parameter parallel management control is further carried out, the diversified auxiliary functions of the window wiper are achieved, and the application range of the window wiper is widened. And a wiper driven by a brush motor and a pneumatic wiper are comprehensively upgraded and replaced.

    本发明公开了一种基于永磁无刷电机驱动控制系统的电动刮雨器,包括传动机构、永磁无刷电机、刮臂刮片;还包括位置传感器、可编程驱动控制器和洗涤器;可编程驱动控制器根据指令控制永磁无刷电机驱动刮臂刮片运行到达位置传感器所处绝对位置时立即或者是延时停止运转;洗涤器包括洗涤泵和液位传感器,可编程驱动控制器可读取液位传感器返回的液位信号控制洗涤泵进行或者是停止工作。本发明利用永磁无刷电机驱动的可编程驱动控制系统,在驱动电机扭矩输出推动刮臂摆动实现基本刮刷功能之外,还进行多线程、多参量平行管理控制,满足了刮雨器多样性辅助功能的实现,全面升级替代有刷电机驱动的刮雨器和气动刮雨器。
