The product life of an actuator is highly dependent on the individual application. Our endurance tests are performed under the following conditions:
|Pre-stress:||0.5 Blocking Force|
|Control signal:||200 Vp-p, trapezoid, unipolar|
|Surface temp:||120 °C|
Under these conditions, the product life of an actuator exceeds 10^9 cycles. Our longest running tests have reached over 6 x 10^9 cycles, corresponding to a permanent operating time of approx. 2 years. This value exceeds the product life of most other electrical and mechanical components in the application environment.
The product life of actuators become enhanced while operating in resonant mode. 10^11 cycles have been reached under the following conditions:
|Pre-stress:||0.5 of Blocking Force|
|Control signal:||40 Vp-p, sine-wave, unipolar|
|Surface temp:||60 °C|
Under DC excitation, actuators can reach a product life of 3,000 hours at 200V as long as the air humidity does not exceed 5% rH.
