SANTA CLARITA, Calif., March 5, 2018 — 
The NCC08-75-3000-3X voice coil actuator from H2W Technologies is a noncommutated, direct-current linear device capable of generating a continuous force of 300 lbs and a peak force of 900 lbs at a duty cycle of 10 percent.
A moving mass of just under 8 lbs allows for a maximum theoretical continuous acceleration of nearly 38 G. The NCC08-75-3000-3X has a stroke of 0.8 in. The voice coil motor requires 4 A of continuous current and 12 A of peak current in order to generate the specified forces. The actuator has a diameter of 7.47 in. and a retracted length of 8.15 in. The moving coil design ensures a hysteresis-free movement as the bobbin is constructed of aluminum, while the noncommutated coil allows for ripple-free motion and no cogging.
The voice coil actuator has been designed with a through hole in the magnet and coil assemblies, allowing 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 through hole would be necessary, such as focusing applications or fiber optic routing.
