DC Motor PWM Speed Control • Previous methods of speed control used resistors to drop current/voltage in either the armature or the field. This results in a loss of electrical energy through the control resistor. • An electronic alternative that is ...
we’re able to adjust a constant DC voltage to different voltage levels. This helps us control a motor at varying speeds. The video demonstrates two common architectures for PWM control. In the first one, we use a buck converter along with a PWM generator to step down the DC source ...
