When the brushless controller of electric vehicle is out of phase
The failure of power supply and brake handle of electric vehicle brushless controller can be eliminated by referring to the troubleshooting method of brushless controller. For brushless controller, there are its unique fault phenomena, such as lack of phase. The phase loss phenomenon of brushless controller for electric vehicle can be divided into two cases: main phase loss and Hall phase loss.
(1) The detection method of the main phase missing phase can refer to the fault elimination method of the brushed controller car of electric vehicle to detect whether the MOS tube is broken down. The MOS tube breakdown of the brushless controller is generally the breakdown of the upper and lower two pairs of MOS tubes of a certain phase at the same time, and ensure the replacement at the same time. Check the measuring point.
(2) The Hall phase loss of the brushless controller of electric vehicle is manifested as the controller can not recognize the Hall signal of the motor.
