Brushless motor for Electric Car

View:3111/16/2018  

"Electric Car Brushless Motor" phase Hall element is generally due to damage caused by a brushless motor. We can lead a relatively Hall output ground lead resistance and relative power by measuring the Hall Hall element, which is judged by comparison only a Hall element failure. To ensure that the motor commutation position accurately, while generally recommended to replace all three Hall elements. Before replacing the Hall element, must figure out algebraic phase angle of the motor is 120° or 60°, 60° phase angle motors general placement of three Hall elements are parallel. The 120° phase angle of the motor, a Hall element in the middle of three Hall elements is flipped 180° position was placed.
