A voice coil actuator consists of two components: a coil on a carrier and a cylinder with permanent magnets. The force and direction of the coil are directly dependent on the direction and strength of the current.
Due to the low mass of the coil, you can achieve very high acceleration . The prerequisite for this is a correspondingly light load. The force required for acceleration can be over 1,100 N. As the voice coil actuator is a direct drive, there are no losses due to the spindle or gearbox.
Voice coil actuators are also available as a kit. They offer the possibility of precise installation and are therefore very cost-efficient.
If you are looking for a linear movement instead of a rotary one, linear voice coil actuators are available. However, you can only realize short distances with these.
