Voice Coil Motor with Built in Positioning Encoder
GEEPLUS DEVELOP FIRST EVER VOICE COIL MOTOR WITH A BUILT IN POSITIONING ENCODER. Giving resolution down to one mmtr, a new Voice Coil Motor developed by Geeplus is claimed to be the first ever with a built in positioning encoder. Incorporating an advanced magnetics count using high strength magnets to develop up to 3N with only a 1W input, the VCM uses the high force and a low, 20gr mass to give high acceleration capability for ultra fast movement. Acceleration is up to 100G. The shaft devices... (read more)
