We have a small test project based on AI, and we need a few Voice coil motors.
Something like 45W which generates a force of ~25N (stroke of ~1.5 inches).
Voice coil motors advantages
- the force is almost linear whatever the position of the stroke is (unlike solenoids)
- reversing polarity reverses the direction as well (unlike solenoids)
However, looking for such pieces of hardware on the Net yielded only two retailers, the price per motor is ~
$1000 which seems to be way overpriced(?)
Any recommendation on where to search voice coil motors? Or is it that hard to make one myself?
