H2W develops highest force voice-coil actuator

January 30, 2018 By Miles Budimir Leave a Comment

H2W Technologies has developed what it says is the world’s highest force commercially available non-commutated DC linear actuator, otherwise known as a direct drive voice coil actuator. The model NCC08-75-3000-3X is capable of generating a continuous force of 300 lb (1,330 N) and a peak force of 900 lb (4,000 N) at a duty cycle of 10% (i.e. 1 second on, and 9 seconds off). A moving mass of just under 8 lb (3.6 kg) allows for a maximum theoretical continuous acceleration of nearly 38 g’s.

The NCC08-75-3000-3X has a stroke of 0.8 in. (20 mm) and a motor constant of 17.6 lb/sqrt(W) (323 N/sqrt(W). The voice coil motor requires 4 A of continuous current and 12 A 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.
