More Information
Summary:An electric actuator 1 includes a motor 5 and a motion conversion mechanism 4 that converts a rotary motion generated by driving the motor 5 into a predetermined motion. A magnet 31 as a sensor target is disposed on a movable part performing a predetermined motion, and magnetic sensors 32 detecting position information of the magnet 31 is disposed around the magnet 31. A magnetic shield plate 34 is disposed between the motor 5 and the magnetic sensors 32, and an outer surface 5e of the motor 5 and an inner surface 34a of the magnetic shield plate 34 face each other with a predetermined gap 35 therebetween.
