In the process of general dc motor running, as long as change the polarity of the magnetic field direction or change the armature voltage, can change it. But these methods work in the brushless dc motor. Because of brushless dc motor flux by the permanent magnets, unable to change direction. Due to the unidirectional conductivity of the semiconductor, the power supply voltage reverse connection is not very convenient, so in this case, usually by controlling the change of the stator winding in order to change the direction of rotation. The detailed practice need to change the commutation control table. for more details, please log on to http://www. hengdrive。 Com 2012 - motor controller co. , LTD9 -13 the Chinese first-class enterprise brushless dc motor controller, creating common, standard the full range of brushless dc motor controller the motor controller.
