Brush’s wear also are connect with the current size of the brush on silver content. The current of series motor Freight three vehicles used is large, the life can not exceed 2000 hours, it would have to be replaced once a few months, the amount of silver of Brush’s prices vary greatly. There are only two connections outside on brush motor, at once as the permanent magnet brush motor switch the connections, it can change the direction of rotation; series motor without permanent magnets, rotor and stator also are windings, of which the stator magnetic field also called excitation magnetic field, but the winding is independent, when used in tandem, it has other name- series motor. Although the series motor also have two outside connections, it different from the exchange of permanent magnet brush motor can that can change the direction of rotation of the connection. Brushless motor, as its name imply, it has not brush inside, Winding current brushless conversion is carried out by an external controller (later referred to brushless motor controller). However, the brushless motor must provide rotor position for brushless motor controllers.
