ACTUATOR, AIR PUMP, BEAUTY TREATMENT DEVICE, AND LASER SCANNING DEVICE |
摘要 |
An actuator includes: a movable body including a single-pole magnetized single pole magnet; and a plurality of electromagnets each having a magnetic core portion and a coil portion for exciting the core portion. The actuator has: a fixed body on which three or more magnetic poles of the electromagnets are disposed at positions orthogonal to the magnetization direction of the single-pole magnet; and an elastic body bridged between the movable body and the fixed body and elastically deforming when current is supplied to the coil portion, thereby supporting the movable body so as to be movable in the magnetization direction of the single-pole magnet and the two-degree-of-freedom direction. The elastic body is attached to the movable body so that the movable center of the movable body matches the substantial center of the generated magnetic torque of the movable body. |
