Description
PWM with common minus.
PWM with common minus.
The easiest PWM speed controller can be made on the NE555 chip.
But in most cases it is a scheme with a common plus. (Mosfets with N-channel are used).
Motor connects between + supply voltages and PWM output.
But in some cases it is necessary to connect the engine between the minus of the supply voltage and the PWM output. In this case, we need another mirror-symmetric scheme with a with a P-channel MOSFET, that I suggest.
