ELECTRICALLY-DRIVEN OPERATION DEVICE

Japanese Patent JP2016062845

A

PROBLEM TO BE SOLVED: To present a braking function before driving end and a manual operation function after driving end while using a magnet motor as a driving source.SOLUTION: An electrically-driven operation device includes: electrification circuits (for forward rotation to be opened/closed by a second contact C2 and for backward rotation to be opened/closed by a sixth contact C6 and a seventh contact C7) which use a magnet motor 36 as the driving source for electrifying an armature 36a of the motor; a short circuit (to be opened/closed by a fourth contact C4, a fifth contact C5 and an eighth contact C8) which short-circuits both terminals of the armature for configuring a closed circuit; and a control circuit 41 for controlling opening/closing of the contacts. The control circuit performs control for closing the second contact and the eighth contact and opening the fourth contact with forward rotation driving start, opening the second contact and closing the fourth contact and the eighth contact during a period where braking is required before driving end, and opening the eighth contact after driving end. A resistor 41d is then connected in parallel to an auxiliary relay 41b that outputs a fifth signal S5 for opening/closing the eighth contact.SELECTED DRAWING: Figure 5
