The NCC08-75-3000-3X has a stroke of 0.8 in [20 mm] and a motor constant of 17.6 lbs/sqrt(watt) [323 N/sqrt(watt)]. The voice coil motor requires 4 amps of continuous current and 12 amps of peak current in order to generate the specified forces. The massive actuator has a diameter of 7.47 in [190 mm] and a retracted length of 8.15 in [207 mm].
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 fiber optic routing.
