摘要： A rotational speed sensor and a first F/V converter cooperatively obtain a voltage signal representing a rotational speed of an engine. A second F/V converter obtains a voltage signal representing a rotational speed of a generator-motor device. A rotational speed difference detector produces a difference between two voltage signals. When the difference exceeds a predetermined value, a voltage comparator produces a high-level signal to activate a warning circuit.

摘要： An alternator for use in an automotive vehicle includes a circuit for detecting initiation of rotation of an engine. Upon detecting the initiation of rotation, excitation current supply to a field winding is started, and thereafter an alternator output is controlled by controlling the excitation current. A resistor is connected to one phase winding of an armature to obtain a voltage indicating initiation of rotation during a period in which no excitation current is supplied to the field winding, and a capacitor is connected to another phase winding to raise the indicating voltage level. Since the indicating voltage induced by a small amount of residual magnetism is increased to a sufficient level by the capacitor, the initiation of rotation can be accurately detected.
