As the shift to automation continues to gain momentum in the industrial sector, servo motors and stepper motors with electric actuators become ... So, if a servo motor has 1.2 Nm of torque at ...

But industry increasingly needs actuators with continuously variable positioning. These actuators have typically been stepper or brushless-dc motors coupled to a means of mechanical transmission.

Here, we demonstrate highly versatile photoactuators, oscillators and motors based ... response using equations (1) and (2): Figure 3: Mechanical modelling of PC/SWNT actuators.
