Title (EN) ELECTRONIC CIRCUIT FOR STARTING A SINGLE PHASE INDUCTION MOTOR
(FR) CIRCUIT ELECTRONIQUE SERVANT A DEMARRER UN MOTEUR A INDUCTION MONOPHASE
Abstract: front page image
(EN)An electronic circuit for starting a single phase induction motor, of the type containing a rotor and a stator with at least one running coil (B1) and one starting coil (B2), for operating jointly with an alternating current source (F), comprising: a trigger electronic switch; a trigger circuit (TR) of said trigger electronic switch; and a blocking circuit (BL) for controlling the trigger pulses of the trigger electronic switch, said blocking circuit (BL) sustaining its blocking state while there is voltage bing induced to the coils of the motor (M) by rotation of the rotor, maintaining said blocking state for a certain time after said induced voltage has been substantially reduced.
(FR)L'invention concerne un circuit électronique servant à démarrer un moteur à induction monophasé, du type contenant un rotor et un stator avec au moins une bobine de marche (B1) et une bobine de démarrage (B2), destinées à fonctionner conjointement à une source de courant alternatif (F), et comprenant: un commutateur électronique de déclenchement, un circuit de déclenchement (TR) dudit commutateur électronique de déclenchement, et un circuit de blocage (BL) pour commander les impulsions de déclenchement du commutateur de déclenchement électronique. Ledit circuit de blocage (BL) conserve son état de blocage pendant que la tension est induite aux bobines du moteur (M) par rotation du rotor, et maintenant ledit état de blocage pendant un certain temps après que ladite tension induite a été sensiblement réduite.
