The invention relates to the technical field of electrical automatic control, in particular to an intelligent direct-current brushless controller. A battery voltage signal, a handle speed control signal, a brake handle brake signal and each path of detection signal output by a motor Hall signal detection circuit of the controller are sent to a microprocessor, the microprocessor controls the power tube bridge wall output circuit through the driver according to each path of input signal, the microprocessor is provided with a first threshold node and a second threshold node according to the battery voltage signal, when the received battery voltage signal is lower than the first threshold node, the LED lamp is turned on, the discharge current with the maximum transmission ratio is controlled to be reduced along with the reduction of the battery voltage, and the output current of the power tube bridge arm output circuit is reduced to reduce the torque of the motor when the received battery voltage signal is higher than a second threshold node. Two control protection function thresholds are set, large current release can be effectively inhibited, so that the battery, the motor and the controller are protected, and the reliability and the practicability of the product are improved.
本发明涉及电气自动控制技术领域,涉及一种智能型直流无刷控制器,该控制器的电池电压信号、手把速度控制信号、刹把刹车信号、电机霍尔信号检测电路输出的各路检测信号被送入微处理器,微处理器根据输入的各路信号通过驱动器控制功率管桥壁输出电路,所述的微处理器根据电池电压信号设置有第一和第二阈值节点,当接收到的电池电压信号低于第一阈值节点时,LED灯亮,并控制传动比率最大放电电流随电池电压降低而降低,在接收到电池电压信号高于第二阈值节点时,降低功率管桥臂输出电路输出电流使电机扭矩下降。本发明设置两个控制保护功能阀值,能有效的抑制大电流释放,从而保护电池,电机、控制器,提高了产品的可靠性和实用性。
