Kumenyekanisha Impeta ya Neodymium ya moteri na moteri
Ibisobanuro ku bicuruzwa
Neodymium nicyuma cyoroshye kandi cyoroshye cya silver-cyera. Neodymium ni paramagnetic cyane. Ikoreshwa ryingenzi rya neodymium riri mumashanyarazi menshi ahoraho ashingiye kuri Nd2Fe14B akoreshwa mumashanyarazi akora cyane kandi akanatanga amashanyarazi, ndetse no muri magnet ya spindle kuri mudasobwa zikomeye hamwe na turbine z'umuyaga. Imashini ya Neodymium iraboneka muburyo butandukanye bwimiterere, ingano n'amanota. Imashini zingana ni nka disiki cyangwa silinderi, ariko hamwe n'umwobo wo hagati.
Impeta NdFeB Magnet Ibiranga
1. Ubushyuhe bwo hejuru bukora
Imashini ya N48H neodymium ifite imbaraga zo kurwanya ubushyuhe bwiza. Kuri NH ya seriveri ya NdFeB, ubushyuhe ntarengwa bwo gukora burashobora kugera kuri 120 ℃.
| Ibikoresho bya Neodymium | Icyiza. Gukoresha Temp | Curie Temp |
| N35 - N55 | 176 ° F (80 ° C) | 590 ° F (310 ° C) |
| N33M - N50M | 212 ° F (100 ° C) | 644 ° F (340 ° C) |
| N30H - N48H | 248 ° F (120 ° C) | 644 ° F (340 ° C) |
| N30SH - N45SH | 302 ° F (150 ° C) | 644 ° F (340 ° C) |
| N30UH - N40UH | 356 ° F (180 ° C) | 662 ° F (350 ° C) |
| N30EH - N38EH | 392 ° F (200 ° C) | 662 ° F (350 ° C) |
| N32AH | 428 ° F (220 ° C) | 662 ° F (350 ° C) |
2. Ibiranga umubiri na mashini
| Ubucucike | 7.4-7.5 g / cm3 |
| Imbaraga zo kwikuramo | 950 MPa (137.800 psi) |
| Imbaraga | 80 MPa (11,600 psi) |
| Vickers Gukomera (Hv) | 550-600 |
| Kurwanya amashanyarazi | 125-155 μΩ • cm |
| Ubushyuhe | 350-500 J / (kg. ° C) |
| Amashanyarazi | 8.95 W / m • K. |
| Byemewe Kwisubiraho | 1.05 μr |
3. Gupfuka / Gufata
Amahitamo: Ni-Cu-Ni, Zinc (Zn), Epoxy Yirabura, Rubber, Zahabu, Ifeza, nibindi.
4. Icyerekezo cya rukuruzi
Imashini zimpeta zisobanurwa nuburinganire butatu: Diameter yo hanze (OD), Diameter y'imbere (ID), n'uburebure (H).
Ubwoko bwa magnetiki icyerekezo cyimpeta za magneti zikoreshwa mu buryo bwa magneti, zikoreshwa na diametrike, rukuruzi ya radiyo, hamwe na magnetiki nyinshi.
