Abstract: The interface circuit (IC) has a single input terminal (i) for to receiving an analogue or digital (PWM) control signal (Vin) indicative of the required speed of rotation of the motor (M). The type of input signal (Vin) is recognised by means of comparator circuits (C1, C2). The input signal (Vin) is processed differently according to its nature in order, in any case, to output an analogue signal (Vo) acceptable by the regulation and control circuit (Z) which pilots the motor (M).

Abstract: The unit includes a support housing (1, 10) containing two ignition coils (20) each for connection to at least one, and preferably two, associated spark plugs (SP). Each ignition coil (20) comprises a primary winding (21) and a secondary winding (24) disposed around the end arms (41) of a magnetic core or circuit formed by only two packs of plates (40) juxtaposed so that together they form essentially a figure-of-8 shape. The packs of plates (40) are identical, essentially E-shaped and are placed close together, face-to-face, so that together they form a squared figure-of-8 shape. Each of the packs of plates (40) has a notch (43) which extends from the back of the E into its central arm (42) and almost up to the edge of the free end thereof. Conveniently, inserts (50) of non-magnetic material are disposed in the notches (43) in the packs of plates (40).
