Matoorada 'servo motor magnets' waxay xaqiijiyaan matoorada servo si ay u sameeyaan xakamaynta xawaaraha saxda ah iyo saxnaanta booska, waxayna u rogi kartaa calaamada korantada qulqulka iyo xawaaraha si loo wado shayga kantaroolka. Xawaaraha rotor ee matoorka servo waxaa gacanta ku haya calaamada gelinta oo si dhakhso ah ayuu uga falcelin karaa.
Tan iyo markii laanta Indramat ee Rexroth ay si rasmi ah u soo bandhigtay MAC magnet joogto ah AC servo motor iyo nidaamka wadista bandhigga ganacsiga Hannover ee 1978, tani waxay calaamad u tahay in jiilka cusub ee tignoolajiyada AC servo uu galay marxalad la taaban karo. Bartamihii iyo dabayaaqadii 1980-aadkii, shirkad kastaa waxay lahayd badeecooyin taxane ah oo dhammaystiran. Dhammaan suuqa servo wuxuu u jeestay nidaamyada AC. Inta badan nidaamyada servo koronto ee waxqabadka sare leh waxay isticmaalaan magnet joogto ah oo isku xiran AC servo motor, iyo darawalka kantaroolku inta badan wuxuu qaataa nidaamka servo booska dhijitaalka ah oo buuxa oo leh meeleyn degdeg ah oo sax ah. Waxaa jira soosaarayaal caadi ah sida Siemens,Kolmorgen, Panasonic,Yaskawaiwm.
Sababtoo ah shaqada saxda ah ee matoorka servo, waxay leedahay shuruud adag oo ku saabsan saxnaanta shaqada iyo waxqabadka sare, taas oo inta badan ku xiran tayada Neodymium magnets ee matoorada servo. Sababo la xiriira kala duwanaansho badan oo guryaha magnetic sare, Neodymium magnet ka dhigaysa servo matoorada miisaan hoose iyo size yar marka la barbar dhigo alaabta magnetic dhaqameed, sida Ferrite, Alnico ama SmCo magnets.
Magnets-ka servo motor, hadda Horizon Magnetics waxay soo saartaa taxane ah darajooyin heersare ah oo Neodymium magnets ah, sida H, SH, UH, EH iyo AH oo leh saddex sifo:
1.High intrinsic coercivity Hcj: sare ilaa>35kOe (> 2785 kA / m) taas oo kordhisa iska caabin demagnetizing magnet ka dibna servo motor ka shaqayn
2. Heerkulka hoose ee dib loo rogi karo: hooseeyo ilaa α(Br)<-0.1%/ºC iyo β(Hcj)<-0.5%/ºC taasoo kordhisa xasiloonida heerkulka magnet waxayna hubisaa matoorada servo si ay ula shaqeeyaan xasilooni sare
3. Miisaanka hooseeya: hooseeyo ilaa 2 ~ 5mg / cm2 ee xaaladda imtixaanka HAST: 130ºC, 95% RH, 2.7 ATM, 20 maalmood taas oo kordhisa iska caabinta daxalka magnets si loo kordhiyo waqtiga nolosha ee matoorada servo
Waad ku mahadsan tahay waayo-aragnimadayada hodanka ah ee ku saabsan bixinta soosaarayaasha matoorrada servo ee leh magnets, Horizon Magnetics waxay fahmeen in magnet-ka servo motor uu u baahan yahay baaritaano dhamaystiran si loo hubiyo tayada adag, sidaqalooca demagnetizationheerkulka sare si aad u aragto waxqabadka xasiloonida shaqada, PCT & SST si ay u bartaan tayada lakabyada daahan, HAST si aad u hesho miisaanka luminta, kuleylinta heerkulka sare si ay u bartaan heerka khasaaraha aan dib loo celin karin, weecasho magnet magnetic si loo yareeyo jitter motor, iwm.
