The working principle of DC motor Drives

DC Drives is to adjust the dc motor speed device, the upper and the ac power connection, the bottom connection and dc motor, DC Drives to alternating current (ac) into two lines of output dc power supply, input all the way to issue magnetic dc motor stator), input all the way to dc motor armature (rotor), DC Drives through the armature dc voltage to adjust the dc motor speed control. At the same time, DC motor gives a feedback current to the governor, the governor according to the feedback current to judge the speed of the DC motor, if necessary to modify the armature voltage output, in order to adjust the speed of the motor again.
