Abstract

The direct current and alternating current supply circuit for electromagnet is used for electromagnets with a fixed core and a moving armature comprises an on-off switch (O), a main winding (M1) and an auxiliary winding (M2) of the electromagnet, a switch (S) actuated by the armature of the electromagnet, a diode Graetz bridge circuits (D1, D2, D3, D4) and resistors (R1, R2). A diagonal (AC) of the bridge circuit (D1, D2, D3, D4) is connected to the supply terminals and the on-off switch (O) and the other diagonal (BI) is connected to the main winding (M1). One of the terminals of the auxiliary winding (M2) is connected to two of the diodes (D3, D4) through resistors (R1, R2). The switch (S) is used to energise the main winding (M1) and pull in the armature and then to energise both windings (M1, M2) and hold the armature and then to energise both windings (m1, M2) and hold the armature.
