Document Type and Number:
Japanese Patent JP7464375
Kind Code:
B2
Abstract:
To stably keep an output mechanism at a target position and control it even when a DC motor is used in an electric actuator.SOLUTION: A holding control unit 17B supplies a holding brake current for holding a rotational angle θpt of an output axis 14 from a driving circuit 12 to each of windings U, V, and W of a DC motor 11 when a deviation between the rotational angle θpt of the output axis 14 and a target angle θsp is resolved.SELECTED DRAWING: Figure 1
