FIELD: electricity.
SUBSTANCE: step electric drive includes electric motor (1), step-down worm reduction gear (2, 3), start/stop mechanism (6) connected to electric motor (1) control circuit (8). Start/stop mechanism (6) is made of flat metal screen (11) from magnetically soft material, which is put on informative axis (5) of reduction gear and has the shape of a half of a circle, on opposite edges of which there arranged are constant magnets (12), (13), and opposite to them on the other side of the screen, there located are reed contacts (14), (15). Screen 11 and control circuit (8) are made so as it is specified in application materials.
EFFECT: simplifying a control circuit, reducing power consumption and improving reliability.
