it is more convenient to use a digital speed sensing with an inexpensive tachogenerator which doesn′t need any tuning. D.
The TDA 1085C triggers a triac accordingly to the speed regulation requirements. Motor speed is digitally sensed by a tachogenerator and then converted into an analog voltage. The speed set is externally fixed and is applied to the internal linear re.
