INDICATING DEVICE IN THE FORM OF ELECTRIC MOTOR Russian patent published in 1994 - IPC

FIELD: indicator-type digital clock. SUBSTANCE: between non-magnetic plates of the body is fixed magnetic circuit 3 with control winding 4 whose coils 5 are positioned in parallel to axle of rotor 6 which is in the form of cylinder-shaped magnet. The diametrically magnetized magnet is made together with indicator. Position of the magnet with de-energized winding 4 is fixed by magnetic circuit column 14. Entering of pulse of respective polarity into winding 3 results in turn of magnet-indicator by half of revolution of shaft. In this case visual image of indicator appears or disappears depending on polarity of pulse. EFFECT: enhanced ergometrics of indicating device as a result of better use of area of concave spot. 5 dwg
