Abstract (en)

[origin: EP0806710A1] The movement is driven by a source of electrical energy including a magnetised rotor (3a) and an inductive winding (3b). Rotation by a coil spring (2) produces an alternating voltage (Ug) between a reference terminal (B0) and a terminal (B1) connected to a full-wave rectifier (5), which supplies the regulatory circuit (1). During each revolution a measuring pulse (IM) is generated (Trig) and compared (Cmp) with a reference signal (FR) from a fixed-frequency oscillator (Osc). When a pulse occurs in advance of the reference signal the rotor is braked, advantageously by a transistor switch (K) receiving a pulse (IF) from a delay register (Tmr).
