Electroactive polymers: see rules of classification in H02N 1/006

electrostatic actuators:

The electroactive polymers (EAPs) are of three types:

1) The EAPs based on some electrochemical effect inside the polymer (e.g. or i.e. ionic EAPs). Electric machines with the same are classified in F03G 7/00.

2/3) The EAPs based on electrostrictive, or electrostatic (or a combination of electrostrictive and electrostatic) effects. Electric machines based on electrostrictive / electrostatic EAPs are classified in H02N 2/00.

Comb shaped motors the direction of movement is parallel to the extension direction of the comb teeth, among others

Comb shaped motors with oscillating movement are classified in H02N 1/006

Including conveyor belt carrying conductive charge carriers charged by induction, i.e. like capacitors.

Influence type generators built as a conveyor belt can be of two types (according to the way the belt is charged): induction charging type and corona charging type.

The corona charging type usually comprises an insulating belt charged by charges generated by corona effect. This type of machine is classified in H02N 1/12 (even if the belt comprises some conductive element)

The induction charging type are a conveyor belt version (i.e. a linear version) of capacitor machines in which conductive charge carriers are charged by induction ( i.e. like capacitors). This type of machine is classified in H02N 1/08.

Machines of the corona charging type in which an (usually) insulating belt is charged by charges generated by corona effect. (if the belt contains some conductive element see Special Rules of Classification).

Influence type generators built as a conveyor belt can be of two types (according to the way the belt is charged): induction charging type and corona charging type.

The corona charging type usually comprises an insulating belt charged by charges generated by corona effect. This type of machine is classified in H02N 1/12 (even if the belt comprise some conductive element)

The induction charging type are a conveyor belt version (i.e. a linear version) of capacitor machines in which conductive charge carriers are charged by induction ( i.e. like capacitors). This type of machine is classified in H02N 1/08.

Electric motors or generators using piezoelectric (PE) or magnetostriction (MS) devices described under H10N 30/00 as primary motion producing or electricity generating parts. In particular:

Linear or rotary motors, including positioners or actuators, based on at least one PE or MS device in cooperation with at least one driven element as mechanical output, e.g. a rotor or translating shaft. The motors can operate based on standing or travelling waves or quasi-static deformation generated by said PE or MS devices;

Generators based on at least one PE or MS device in cooperation with at least one driving element as mechanical input;

Aspects such as the operating principle, mechanical construction built around said PE or MS devices, driving or control circuits or methods, and methods relating to manufacturing of the engines.

Further information:

In this group the PE or MS devices are seen as black boxes which could in principle be replaced by any device of equal electromechanical conversion functionality.

If no relevant details of the PE or MS devices themselves are given classification is done only in this group. If particular details of the PE or MS devices are concerned, e.g. these devices appear to be relevant to other technical fields as well, classification in H10N 30/00 is required. If no details other than the PE or MS devices themselves are described, e.g. PE stacks or benders are just called actuators or generators, classification is done only in H10N 30/00.

In this group, in the absence of an indication to the contrary, an invention is classified in the last appropriate place.

Motors wherein the type of motion is irrelevant, e.g. driving devices which may be used to advance a driven body in arbitrary directions, and details thereof.

Details of linear or rotary motors covered by H02N 2/02 - H02N 2/16 wherein the type of motion is irrelevant, e.g. of mechanical, electrical or thermal nature, such as friction interfaces between driving and driven parts.

Linear motors comprising at least two clamping devices and one intermediate driving device which are excited in sequence to grip and move a driven body.

Linear motors comprising a driving device which is excited asymmetrically during multiple phases such that in one phase the static friction between a driven body and its support is overcome, thereby effecting a sliding motion between them.

Linear motors wherein a driven body, e.g. a translating rail, is moved by vibrations of one or more vibrators pressed against the driven body.

Rotary motors wherein a rotor is moved by vibrations of one or more vibrators pressed against the rotor.

Rotary motors wherein a cycloid type motion of a rotor is caused by radial or tangential driving devices excited in different phases.

Rotary motors wherein a substantially rod-shaped vibrator excited to axial vibrations, e.g. a longitudinal mode, combined with lateral vibrations, e.g. a bending or torsion mode, creates a hula-hoop like progressive wave on its surface, thereby driving a rotor.

Rotary motors wherein a rotor is moved by Rayleigh type surface acoustic waves only.

Generators based on the collection of free electrical charges in the flow. e.g. inonized gas in a thermal engine exhaust.
