Optimization Of A Non-Contact Single Phase Drive Ultrasonic Micromotor: Via Design And Analysis Of Engineered Stator Curvature And Surface Acoustic Streaming Actuators
… leading to CMOSelectronics compatible ultrasonic micromotors. The MUMPS/PZT motor operates with a drive voltage of 4 - 10 Vpp in the frequency range of 100 kHz - 5 MHz, creating rotation through frictional coupling and acoustic streaming in the rotor-stator gap. Using interferometer measurements, …
