Lee Sheng-electronics factory Teaches you how electric car controller fails when the electric vehicle maintenance brushless controller Phase Brushless electric vehicle controller power failures and the gate of the brush can refer to a faulty controller Remedy be thoroughly removed, Dongyang car battery charger, brushless controller concerned, as well as its characteristic symptoms, such as phase. Electric car brushless controller Phase phenomenon can be divided into the main phase and phase Hall phase two cases. 1, the main phase missing phase detection method can refer to the electric car brush controller Speed ??troubleshooting method to detect whether MOS tube breakdown, car battery charger manufacturers, brushless controller MOS tube breakdown is usually up and down a particular phase two a pair of MOS pipe breakdown at the same time, when replacing ensure simultaneous replacement. Check measurement points. 2, Hall lack of electric vehicles brushless controller with the performance of the controller does not recognize the motor Hall signals. Lee Sheng-electronics factory Teaches you how faulty electric vehicle controller maintenance when referring to electric cars brushless controller no output brushless controller checks the main phase diagram, if voltage measuring chip input and output pins and turn the rotation angle There are correspondence, you can determine which chip is faulty, replace the same type chip to troubleshooting. Car battery charger manufacturers, Dongyang car battery charger, Lee Sheng-electronics factory major brands provided by Lee Sheng Yongkang Electronics Factory.
