This rotary voice coil actuator can generate a continuous torque of 1.29 N-m
and a peak torque of 3.88 N-m
at a duty cycle of 10% (that is, one second on, and nine seconds off) in each coil on a 102-mm rotation arm.
Dynamic holding torque values are 0.6 N-m
(5.3 in-lb) and 1.4 N-m
(12.4 in-lb) for the X motion axis, 1.0 N-m
(8.8 in-lb) and 2.0 N-m
(17.7 in-lb) for the Y motion axis, and 1.3 N-m
(11.9 in-lb) and 2.6 N-m
(23.9 in-lb) for the Z rotational axis.
At the highest loading used, the difference in DL90 for the two blacks was 0.7 N-m compared to a change of 0.8 N-m for a change in loading of NS carbon black from 40 to 60 phr.
At each loading, the difference in DL90 is approximately 0.45 N-m compared to a change in DL90 of 0.8-0.9 N-m for a 20 phr change in carbon black loading.
They provide 4.57 N-m
to 510 N-m
continuous torque, peak torque to 1,017 N-m
and speeds to 2,500 rpm.
