An electromagnetic actuator comprises two armatures which are relatively movable to define a stroke and which form a main magnetic circuit the reluctance of which is variable between the ends of the stroke. A secondary magnetic circuit is formed between the armatures and its reluctance is also variable between the ends of the stroke, the variation being different to that of the first circuit to allow the relationship between the force of the actuator and the stroke position to be trailored to suit different requirements.

Electromagnetic actuator comprising at least two distinct magnetic

An alternator has a rotary inductor carrying permanent magnets rotatable about field windings of a fixed armature and supported on a hollow shaft. The shaft forms a housing for a cooling fan and optionally also an electronic power switching device for rectifying and regulating the alternator output. The fan inside the shaft thus cools the switching device. A separate fan incorporated in a radially outer portion of the inductor rotor cools the field windings of the armature.

Motor-vehicle alternator having a rotary inductor

An ignition coil for an internal combustion engine comprises a magnetic c having a plurality of arms lying at an angle to each other, a primary inductive winding on one of said arms and a secondary high voltage winding on another of said arms. The primary and secondary windings are on adjacent arms and have intersecting axes, with a plane through one end of one of said windings perpendicular to the axis of said one winding intersecting both ends of the other winding.
