Voice Coil-Linear Motors

Moving Coil Technology (Voice Coil)

These actuators have amazing control over both force and speed.
They feature:

– High cycle yet controlled low force
– 100million+ Cycle Long Life
– Up to 40G acceleration

At the heart of all SMAC actuators is the moving coil, also
described as a voice coil actuator. The essential principle is the
same as you will find in any permanent magnet loudspeaker.
The coil is enclosed in a magnet housing, and by passing a
current through the coil, a magnetic field is generated. The coil
reacts to this field, generating the force of the motor.
