摘要： A method for driving a linear oscillating motor and a linear oscillating motor are provided. The motor includes a fixed magnetic member, a movable member having a magnet and being supported to oscillate relative to the fixed magnetic member, a detector that detects displacement of the movable member, and a control that oscillates the movable member by sending drive current to a coil of the fixed magnetic member. The method includes controlling, during a first half-period that occurs within a full amplitude period of the movable member, the drive current based upon the output of the detector. The method also includes controlling, during a second half-period that occurs within a fill amplitude period of the movable member, the drive current based upon a fixed drive current waveform.

摘要： A control system for a linear vibration motor capable of eliminating necessity of a separate sensor of detecting the motion of the motor. The linear vibration motor includes a stator provided with a winding, and a vibrator provided with a permanent magnet. The winding is fed with a drive current to generate a magnetic field which interacts with the permanent magnet to cause the vibrator to reciprocate linearly relative to the stator for producing a vibration. The control system includes a controller which detects an ongoing amplitude, i.e., the motion represented by the displacement, speed, or acceleration of the vibrator and provides ON-periods of feeding the driving current to the winding in a varying amount based upon the ongoing amplitude detected in order to keep a vibration amplitude of the vibrator constant. The controller is characterized to provide OFF-period in which the controller instructs not to feed the drive current and in which the controller detects a voltage developed across the winding and determines the ongoing amplitude based upon the detected voltage. Thus, the winding can be best utilized commonly to drive the motor and to sense the ongoing amplitude or motion of the vibrator, thereby eliminating an additional sensor for detection of the motion of the vibrator.

摘要： A surface micromachined micromagnetic actuator is described, wherein rotary actuation is accomplished by a member pivotably mounted on the surface of the substrate. Angular motion of the member about the pivot point is imparted by the interaction of a magnetic tab affixed to the member, with flux generated in the gap of an electromagnetic core. Rotary motion is restricted to less than 360 degrees by using an integrally formed hinge between the pivoting member and the pivot point, rather than by a more complex bearing. By virtue of this design, a large range of motion can be achieved without requiring a true bearing to be fabricated in the device. The pivoting member is also constrained in either of two stable positions upon de-energization of the electromagnetic core, by the attachment of a bistable spring between the pivoting member and the substrate.

摘要： A driving device for an oscillatory actuator in which a FLL (Frequency Locked Loop) is employed for detecting an electromotive force generated in a driving coil resulting from mechanical oscillation during a period in which no driving current is supplied to the oscillatory actuator, and for controlling an oscillation frequency on the basis of a relative time ratio between positive and negative polarities of the electromotive force to thereby pull a driving frequency into a neighborhood of a self-resonance frequency of the oscillatory actuator.

摘要： An electromagnetic actuator including a fixed stator having two poles. The stator includes one or two excitation coils. The actuator further includes a mobile part provided with thin permanent magnets magnetized along an air gap direction. The mobile member includes at least two independent elements which are each mobile along directions parallel to the air gap plane intersection and the fixed stator median plane, in opposite directions. Each of the mobile parts has three thin magnets alternately magnetized, which are either integral or not with a yoke made of soft material. The thin magnets of the mobile elements are magnetized along a direction opposite to the corresponding thin magnets of the second mobile element or of the adjacent element, the yokes defining with a fixed stator part a yoke.
