WebJan 29, 2024 · The method is valid even if the frequency seems over the top. Measure the DC resistance of the winding. Then add a series resistor that will make the motor + resistor value match the generator output - probably 50 Ohms. Apply a signal, perhaps a couple of volts and measure the current by reading the voltage across the external resistor. WebDec 17, 2024 · I am driving a brushed DC motor (Cytron gear motor) using a gate driver to do PWM motor speed control. My expectation. I expected a triangular current wave, …
