Non-Commutated DC Voice Coil Linear Actuator, NCC14-78-830-1SM
H2W Technologies has developed a high force non-commutated DC linear actuator, otherwise known as a direct drive voice coil actuator, designed specifically for use in cryogenic environments. Material choice and design parameters were implemented such that the motor can operate without degradation or damage when placed in a cryogenic environment. The model NCC14-78-830-1SM can generate a continuous force of 92 pounds [410 N] and a peak force of 294 pounds [1300 N] at a duty cycle of 10% (i.e. 1 second on, and 9 seconds off). A moving mass of 4.4 lbs [1.97 kg] allows for a maximum theoretical continuous acceleration of more than 20 G’s.

The NCC14-78-830-1SM has a stroke of 1.4 in [35.6 mm] and a motor constant of 6.9 lbs/sqrt(watt) [31 N/sqrt(watt)]. The voice coil motor requires 3.8 amps of continuous current and 12.1 amps of peak current in order to generate the specified forces. The actuator has a diameter of 7.87 in [200 mm] and a retracted length of 3.50 in [89 mm].
