Design of an asynchronous electrostatic motor

Review of Scientific Instruments, 1990
An asynchronous electrostatic motor that works under a high-voltage pulse controller using LED-phototransistor photosensors is described. The motor produced the torque 1030-dyn-cm at 1500 V and attained the power 0.8 mW at 80 rpm in n-hexane.
