Abstract

PURPOSE:To minimize energy loss, by impressing counter-electromotive force, which is generated by stopping conduction to one electromagnetic coil, upon the other coil so that a circuit response is accelerated. CONSTITUTION:Electric power supplied from an astable power source is impressed upon an electromagnetic clutch 11 (at the time (a)) to actuate the clutch 11. When supply of electric power to the clutch 11 is interrupted at the time (b), counter-electromotive force (A) occurs in a coil 10inside the clutch 11. The counter-electromotive force A is added through a diode 17 to voltage impressed to a coil 12 of an electromagnetic brake 13 (at the time (b)) to operate the brake 13. When the brake 13 is stopped at the time (c), counter-electromotive force (B) occurs in the inside coil 12 the same as in case of the electromagnetic clutch 11. This counter-electromotive force generated then is available for operating the other electromagnetic coils.

However, in electromagnetic clutches and electromagnetic brake devices that use conventional electromagnetic coil drive circuits to control motors connected in series, both electromagnetic coil drive circuits are supplied with power from an unstable power source. Since the voltage decreases due to the operation of the load of one electromagnetic coil drive circuit, the operating speed of the other electromagnetic coil drive circuit becomes slow. Since this method requires several times as much energy as the conventional method, the power supply capacity and control circuit itself become large, resulting in a disadvantage that energy loss becomes large.
