It is possible to create an electrostatic motor using capacitance and electric fields as the energy transport. One example is: some ‘high end’ audiophile speakers use electrostatic principles — rather than magnetics — to create sound .
The problem with using electrostatic fields is the energy density. There just isn’t enough of it compared with magnetic fields. For a given volume, weight, power consumption, load, etc. magnetic energy storage is by far more efficient than electrostatic energy storage.
