Title:
駆動回路
Document Type and Number:
Japanese Patent JP5527181
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the size of wiring connected to a drive source of an actuator, and to prevent the enlargement of a connector on a control substrate connected to the wiring.SOLUTION: Switching contacts C1 to C4 of a changeover switch S1 are connected to phases of flapping motors M1 to M4, respectively, on a one-to-one basis. In a changeover switch S2, switching contacts which are the same in numbers of the respective switching contacts C1 to C4 of the changeover switch S1 are connected to phases, respectively, which are excited succeeding to the phases of the flapping motors M1 to M4 connected with the switching contacts C1 to C4 of the changeover switch S1, on a one-to-one basis. A microcomputer 101 performs excitation control using a switching signal and a drive signal, and the switching control of the changeover switches S1, S2. The microcomputer 101 controls the opening/closing of opening/closing switches connected to the flapping motors M1 to M4, and varies the motors to be driven and the number of the motors.
