Title:
ELECTRIC MOTOR-DRIVEN ACTUATOR DEVICE PROVIDED WITH POWER INTERRUPT MECHANISM AND ELECTRIC MOTOR-DRIVEN ACTUATOR DRIVE GEAR
Document Type and Number:
Japanese Patent JP3685932
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric motor-driven actuator device, provided with a power interrupt mechanism capable of quickly resetting a magnetic coupling to coupling conditions.
SOLUTION: An action command generating means 85 actuates a drive signal generating means 82, based on an ordinary action mode until a step out condition detection signal Sa is made input. Supply of power to an electric motor 4 is stopped in an electric motor drive power generating part 81, by stopping an output of a drive signal in the drive signal generating means 82, when a step out condition detection signal Sa is input. A hold brake action control means 84 maintains a hold brake 7 in an operating condition during at least the inputting of the step out condition detection signal Sa. The action command generating means 85 actuates the drive signal generating means 82, in accordance with a reset action mode when a reset signal SR is input. In this way, the electric motor drive power generating part 81 restores magnetic coupling to a coupled condition, by rotating the electric motor 4 through a prescribed angle.
