FIELD: electricity. ^ SUBSTANCE: invention describes electromagnetic drive (EMD) and circuit breaker (switch) with such drive. Drive comprises body, where two channels are formed, having length in longitudinal direction, and middle partition between two specified channels; the main magnetic element for generation of magnetic field arranged on both sides of two body channels; and movable element, in the middle of which there is a middle partition arranged, where coil is installed, which produces the body and is wound in direction orthogonal to longitudinal direction of channels, besides the left and right sides of movable element pass through channels, and its front and back sides are open to outside, moreover, coil is arranged with the possibility of reciprocal motion along channels as current is supplied into coil in direct or reverse direction. ^ EFFECT: simplified design and manufacturing, improved compactness and reliability of EMD, which is characterised by stable motion of movable part and higher retention force, which expands area of drive application. ^ 29 cl, 44 dwg |
