Clean energy is one of the six application categories listed on the company's site, and this guide treats it as a category for specification checks. It names no energy device, no generating figure and no performance result, because none is published for this category on the company's pages. The checks that matter in clean energy use are the same checks that matter everywhere — shape, size range, grade temperature series, magnetization direction, fixing and operating temperature — applied with attention to the conditions clean energy equipment actually creates.
Scale, temperature and environment
Clean energy equipment often operates outdoors and over long periods, so the operating temperature range and the environment deserve explicit lines in the inquiry: the highest temperature the magnet will see, the lowest where relevant, and any exposure to moisture or weather that affects a coating question. Discuss the grade series against the shared temperature table using the highest operating temperature, from 80°C for the N35–N52 series to 200°C for the 28EH–38EH series, and state the temperature as a figure rather than letting a series be chosen from its name. If the temperature range is wide, say so, because a series discussion that covers only the average temperature has not covered the extremes.
Scale also affects how an inquiry should be written. A clean energy inquiry may involve larger quantities or larger parts than a small-device inquiry, but quantity does not change the specification items: shape, dimensions inside the published range, grade series and direction are still required, and quantity and lead time are still asked about in the buyer-imperative form used throughout this site. Please confirm minimum order quantity and lead time before ordering. A large-quantity inquiry without a complete specification will still be answered with questions, because quantity cannot substitute for geometry.
Shape selection without borrowing figures
Shape selection in clean energy use follows the site-wide rule: read the detail page for the shape needed, and do not borrow a dimension from another shape's table. Arc and segment magnets are sometimes discussed in rotating equipment contexts because a curved magnet can follow a curved surface, and the arc guide on this site explains the three customized figures — outer diameter, inner diameter and angle — that an arc inquiry must contain. Ring magnets are sometimes discussed where a through opening is needed, and the ring guides explain the diametrical, radial and axial directions that must not be confused. In both cases the category context does not add a specification; the shape page does.
Where the geometry does not fit any of the six published shapes, the custom-shape route applies, with a dimensioned sketch, the grade series, the direction described in plain words, and the operating temperature and environment. A forced fit into the nearest shape — ordering a block when the part needs an arc's curvature, for example — produces a magnet that matches its order and fails its part, which is worse than an extra round of questions before ordering.
What this category page does not claim
Nothing on this page claims that magnets have been supplied for clean energy use, to any project, or for any particular device, and no generating figure is quoted, because none is published. Application categories are headings, and this site preserves them as headings. A buyer who needs evidence of supply for a specific clean energy use should ask for it explicitly, and should not treat a category page as evidence of supply. Certificates are available upon request rather than asserted here, coating is an open question to confirm before ordering, and warranty terms are unavailable on the published pages and should be confirmed before ordering. Those three sentences, repeated across the category guides, are the honest form of every unverified item on this site.
Questions to send with a clean energy application inquiry
A specification that can be answered names four items together: the shape family, dimensions inside that family's published range, the grade temperature series, and the magnetization direction exactly as listed for that shape. Add the operating temperature and the fixing method where they affect the choice, and ask coating and warranty as open questions. Please confirm minimum order quantity and lead time before ordering. Warranty terms are unavailable on the published pages — please confirm warranty terms before ordering. Certificates are available upon request; no certificate number or issuing body is published here.
An inquiry that names only a grade, or only a size, will be answered with questions rather than a confirmation, because neither item alone is a complete specification. The extra sentence that states the direction in plain words, or that gives the mating dimension for a fixing, is often the sentence that prevents a second round of correspondence, and it costs nothing to include at the start.
Frequently asked questions
Which grade series should I discuss for neodymium magnets in clean energy?
Discuss the grade series against the shared grade maximum working temperature table, using the temperature the magnet will actually see in service, including heat from neighbouring parts. The series run from N35–N52 at 80°C through the M series at 100°C, the H series at 120°C, the SH series at 150°C and the UH series at 180°C to the EH series at 200°C. State the operating temperature as a figure in the inquiry, because a grade name without its temperature row has not been specified for a warm environment, and the review needs the temperature to confirm the series discussion rather than infer it from a name alone.
How exactly should I state the magnetization direction?
Copy the direction exactly as listed for the shape named in the inquiry, and do not substitute a synonym that feels equivalent, because the same word can describe a different arrangement on a different shape. Where a drawing uses a different convention, add a plain-words description of the pole positions alongside the listed term, so the review can reconcile the two without guessing. A direction that is assumed rather than confirmed is a common source of a magnet that is dimensionally correct and magnetically wrong for its fixing, so the extra sentence describing the poles is worth writing even in a short inquiry.
What should I ask about coating, warranty and certificates?
Please confirm coating requirements before ordering, because coating type names were not transcribed from the company illustration and no coating type is named on this site; state the operating environment with the coating question so the answer can be specific. Warranty terms are unavailable on the published pages, so please confirm warranty terms before ordering rather than assuming a term. Certificates are available upon request: name the certificate required and its purpose in the inquiry, because no certificate number, issuing body, scope or validity period is published here, and a named request can be matched to the order it belongs to.
What if my size or combination is not in the published range?
Ask whether it can be made, and send the dimension as written rather than rounding it into the published range. A value outside a shape range, a direction not listed for that shape, or a combination of features from two shapes should be raised as an explicit question, with a dimensioned sketch where the geometry is curved, holed or otherwise not captured by a single size figure. Please confirm minimum order quantity and lead time before ordering. A question asked before ordering costs one message; a forced fit into the nearest published table can cost the whole part, because a magnet that matches its order and fails its fixing is worse than an extra round of questions.
