Brushless dc gear motor speed controller and current relationships, study together! Any brushless dc gear motor speed controller and current have no direct relationship, they can be seen as the motor controller of two degrees of freedom, how much is this moment two values specific, is made up of input voltage and resistance moment and the moment on the size of the two values. Detailed points, can according to the mathematical modeling to determine the motor controller. Such as: idling outside brushless dc gear motor drive controller, speed can be any value, but the current is always zero; Fixed rotor motor controller, no matter how to voltage, is proportional to the current will change, but the speed is always zero. So that is no necessary link between. My company's products are superior in quality, reasonable price, warmly welcome friends from all walks of life to discuss cooperation, win-win development! The company all staff look forward to your visit and cooperation!
