This paper proposes a special Halbach structure for the magnetic circuit design of voice coil motors(VCM). The permanent magnets arranged by the special Halbach array are stators and the coils are ...

This paper investigates a novel structure voice coil motor (VCM), which is used in ventilator. The VCM controls on and off of the valve of ventilator, so steady thrust and fast response are needed.

AiroTouch includes two three-axis high-bandwidth accelerometers attached on the two tools of the da Vinci to measure vibrations, an audio mixer that processes the sensed vibrations and outputs them to ...
