Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez] demonstrates ...

A voice coil actuator, also known as a non-commutated DC linear actuator, is a type of direct drive linear motor. The name “voice coil” comes from one of its historically first applications: vibrating ...

Compared to the vast majority of systems that require motion control, medical devices typically tend to be smaller and lighter, simply because they are often portable/mobile systems that are ...
