The invention discloses a dual-motor controller for a scooter. The dual-motor controller comprises an MCU processor used for receiving and processing signals, a power supply interface used for being connected with an external power supply, a DC-DC step-down module and an LDO linear step-down module which are used for carrying out step-down processing on voltage, two groups of driving circuits and two groups of MOS full-bridge array circuits which are used for respectively controlling two motors, and two groups of three-phase current detection modules used for processing the current collected by the two groups of MOS full-bridge array circuits respectively. According to the technical scheme, the structure of an existing motor controller is improved, double-motor single-controller control is achieved, cost is reduced, the space occupancy rate is reduced, and wiring is convenient.

    本发明公开了一种用于滑板车的双电机控制器,包括用于进行信号接收和处理的MCU处理器、用于与外部电源连接的电源接口、用于对电压进行降压处理的DC‑DC降压模块和LDO线性降压模块、用于分别控制两个电机的两组驱动电路和两组MOS全桥阵列电路、用于分别对两组MOS全桥阵列电路采集到的电流进行处理的两组三相电流检测模块。本发明技术方案改善现有电机控制器的结构,实现双电机的单控制器控制,降低成本,减小空间占用率,方便布线。
