Instructables member Joehan has published details of a DIY electrostatic motor or “capacitor motor” that has been created using 3D printing and is capable of providing 2 Watt HV power.
The DIY electrostatic motor has been built using using standard 3D printing filament and a little aluminium or copper foil, and all files for the design are available to download from the Instructables website.
A electrostatic motor works differently than the conventional electric motor and uses the interaction between the motor’s magnetic field and winding currents to generate force. Watch the video below to see the awesome 3D printed version in action. Joehan explains more about his design.
“Goal: No ball bearings, easy mounting, new different design with low power requirements. The electrodes have a sharp edge at one side which will only fit in one direction to the base – towards the rotor blades. The rotor blades need also be covered with foil because it will receive the charge from the electrodes.
When you have glued or used self-adhesive foil for the eight motor blades and at least two electrodes you can add a piece of wire ~ 50 mm long e.g. the bigger paper clips. The wire has to be strong enough to hold the rotor in place and goes into the middle hole of the base. It will not fall through – just put it in and then take the screw_top.stl (alias the nut) printed part and screw (press fit by closing the screw) it together with the base to fix the wire.”
