Abstract: An electric motor includes a permanent magnet rotor unit and a stator unit. The permanent magnet rotor unit includes a spindle, at least one magnet fixedly disposed beside the spindle, at least one magnetic yoke fixedly disposed at an outer end of the magnet. The stator unit includes a cylindrical extension body. At least one coil is provided on the extension body. The extension body with the coil is mounted to the space between the magnet and the magnetic yoke. The electric motor doesn't use silicon steel plate, so it is light in weight. When the electric current is outputted, it doesn't need rectification. The magnetic field lines won't be diffused and interfere with each other to enhance the magnetic flux effectively.

Abstract: A capsule-type actuator includes a first capsule-shaped part, a second capsule-shaped part, and a connecting part. The interior of the connecting part is provided with a rotating member. A traction member is wound on the rotating member, and two ends of the traction member are connected to the interiors of the first capsule-shaped part and the second capsule-shaped part, respectively. When one capsule-shaped part is deformed to reduce its interior volume, the other capsule-shaped part will increase its interior volume accordingly, such that the traction member is pulled to actuate the rotating member. Through reciprocating motion, the rotating member is turned clockwise and counterclockwise. An output end of the rotating member is adapted to generate electric power.

Abstract: A slide-type actuator includes a fixing unit, a drive unit, a rotating unit, and a traction unit. The drive unit can slide relative to the fixing unit for reciprocation. The rotating unit is disposed on the fixing unit. After the traction unit is wound on the rotating unit, two ends of the traction unit are connected to turning members of the fixing unit and the drive unit, respectively. When the drive unit slides relative to the fixing unit, the traction unit is pulled to actuate the rotating unit. Through reciprocating motion, the rotating unit is turned clockwise and counterclockwise. An output end of the rotating unit is adapted to generate electric power.

Abstract: A traction-type actuator includes a frame, a first actuating unit, a second actuating unit, a rotatable member and a traction member. The rotatable member is disposed on the frame. The first actuating unit and the second actuating unit are located at two sides of the rotatable member. The traction member has a strip shape and can be curved and wound. The traction member has two ends fixed to the frame and is in a tightened state. The traction member winds through the first actuating unit, and then winds on the rotatable member, and finally winds through the second actuating unit. When the first actuating unit is actuated, the second actuating unit will be towed, vice versa, the first actuating unit and the second actuating unit are push-pull by the traction member so that the rotatable member is turned clockwise and counterclockwise.
