Tiny And Precise

 

 
Force Motor PZT measures 44 mm long and 15 mm in diameter. A piece of Invar in the load path elastically stretches during motor operation. The thin-walled section is 1.15-mm thick and acts as a stiff spring. The PZT pushes against the body and is constrained by the 8-mm nut, stretching the thinwalled member. The Force Motor can travel up to 4 mm and has a tuning accuracy of 0.04 nm. A PZT motor is driven by an analog servo using proportional and integral feedback. The microcontroller module accepts data from the telemetry module and can accept data from another computer. The microcontroller controls both the command module and stepper motor module. The red and blue graphs illustrate
