Speed is primarily set by applied voltage. Current measurement may be used to correct for the torque related speed reduction.my final goal is to find the speed of the motor from current measurement
I have one question ; should not the current waveform be like this ?
No. The motor current should be triangular (integral of the rectangular motor voltage). The current through an inductor can only change continuously. The shown waveform clarifies that the motor doesn't behave purely inductive.should not the current waveform be like this ?
