My expectation. I expected a triangular current wave, ramp up when PWM on, ramp down when PWM off. Like this (with sine speed modulation): My observations. However, instead I observed the following: Measured across 1 ohm resistor
WebBrushed DC motors consist of four key components; the stationary magnet (called a stator), the rotor, the commutator and the brushes (see Figure 1). The rotor consists of … 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.
Webolds. The higher current level for triggering fast recirculation is set little below the max current level avail-able by the IC. Figure 10 is the current waveform observed on the oscilloscope during few diagonal inversions.
