Abstract (en)
The motor circuit (1) includes the main motor winding (2), a switch (5) and a control unit (4). A priming unit (6) connects the main winding (2) and the
control unit (4) to the mains, when the main winding is isolated, during the starting procedure. The circuit (1) for starting a motor includes the main
motor winding (2) and a switch (5). A control unit (4) controls the operation of the switch unit (5). This control unit is connected to the main winding
(2) and to the switch (5) isolating the winding (2) and the control unit (4) from the mains (3). A priming unit (6) connects the main winding (2) and the
control unit (4) to the mains, when the main winding is isolated. The circuit may also include an auxiliary motor winding, with the priming unit being
arranged to connect the main winding and the control unit to a half winding, comprising half of the auxiliary winding. The priming circuit may be an
RC circuit.
Abstract (fr)
L'invention concerne un circuit (1) d'asservissement comprenant un enroulement principal (2) d'un moteur, un commutateur (5), une unité de
contrôle (4) asservissant le commutateur (5), l'unité de contrôle (4) étant connectée à l'enroulement principal (2) et le commutateur (5) isolant
l'enroulement (2) et l'unité de contrôle (4) du réseau (3), un organe (6) d'amorçage reliant l'enroulement principal (2) et l'unité de contrôle (4) au
réseau (3) lorsque l'enroulement principal (2) en est isolé. Le circuit d'asservissement permet de démarrer le moteur et de prélever une tension dans
le moteur pour alimenter l'asservissement du fonctionnement du moteur. <IMAGE>
