FIELD: electric engineering. ^ SUBSTANCE: circuit of polarised electromagnet connection contains current source, breaker, normally closed contacts, polarising and control windings. Windings are connected serially and are connected to current source through breaker, and normally closed contacts are connected parallel to control winding, which when broken connect control winding for electromagnet actuation. ^ EFFECT: increase of fast-action without increase of dimensions and weight. ^ 2 dwg |
