Title:
ELECTROMAGNETIC ACTUATOR AND BLADE DRIVING DEVICE FOR CAMERA
Document Type and Number:
Japanese Patent JP2015106037
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent interference between a terminal and other parts, damage, or the like by improving assembling workability, while achieving reduction in size, thickness, and cost, in an electromagnetic actuator.SOLUTION: In the electromagnetic actuator including a rotor 50 including a permanent magnet and an output part, an upper frame 60 freely rotatably supporting the upper end of the rotary shaft 51 of the rotor, a lower frame 70 detachably connected to the upper frame, to freely rotatably support the lower end of the rotary shaft of the rotor and including an attachment part 77 attached to another member, a coil for excitation 80 wound around the upper frame and the lower frame, and a cylindrical yoke 90 arranged around the coil, the lower frame 70 includes two terminals 75 and 75 around which both ends of the coil are wound. Thus, the interference between the terminal and other parts, the damage, or the like can be prevented by improving the assembling workability, while achieving the reduction in size, thickness and cost.
