The NCC08-75-3000-3X has a stroke of 0.8” (20mm) and a motor constant of 17.6lbs/sqrt(watt) (323 N/sqrt(watt)). The voice coil motor requires 4A of continuous current and 12A of peak current in order to generate the specified forces. The massive actuator has a diameter of 7.47” (190mm) and a retracted length of 8.15” (207mm).
The moving coil design ensures a hysteresis free movement as the bobbin is constructed of aluminum while the non-commutated coil allows for ripple-free motion and no cogging. The voice coil actuator has been designed with a thru hole in the magnet and coil assemblies. This allows for the integration of a shaft and bearing system through the center of the motor. Alternatively, the actuator can be used in many applications where a thru hole would be necessary such as focusing applications or fibre optic routing.
