<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic actuator for driving a radar produced at a low cost while reducing weight in the device total unit by eliminating wiring to a movable part so as to improve durability. <P>SOLUTION: In the electromagnetic actuator for driving the radar, first permanent magnets 11a, 11b is set to movable members 9a, 9b so as to be driven by repulsive force of second permanent magnets 12a, 12b set to fixed members 10a, 10b, and repulsive force or attractive force of electromagnets due to coils 15a, 15b and cores 14a, 14b, so as to swivel a reflective mirror 1. By arranging the second permanent magnets 12a, 12b and the cores 14a, 14b to face the first permanent magnets 11a, 11b so as to eliminate wiring to a movable part, to durability is improved, a movable coil and a movable core of large mass is eliminated so as to reduce the weight of the movable members 9a, 9b, further workmanship at a low cost is improved. <P>COPYRIGHT: (C)2004,JPO</p> |
