Akachinja Kusada Motor Magnets

A switched reluctance mota imhando yakasarudzika yemota ine rotor ine akawanda pole pairi, imwe neimwe pole pairi ine magineti uye kusada. Akachinja kusada mota anowanzo shandiswa mumashandisirwo anoda yakakwirira yekutanga torque uye nekushanda kwakanyanya, senge mota dzemagetsi uye madhiraivha emaindasitiri.

Mune inochinja kusada mota, magineti anowanzo gara magineti uye anoshandiswa kugadzira inogara magineti. Magneto-resistors anogadzirwa nemagineti zvinhu izvo zvinodzorwa nemagetsi ikozvino kugadzirisa simba uye kutungamira kweiyo magineti. Kana ikozvino inopfuura nekusada, iyo magnetism yekusada inowedzera, ichigadzira simba remagineti rinokwevera magineti kune kusada kuri pedyo nayo. Izvi zvinoita kuti rotor itenderere, iyo inotyaira mota.

Iyo magineti inoita basa mukugadzira inogara magineti mune inochinja kusada mota, uye kusada kunogadzirisa simba uye gwara remagineti kudzora kushanda kwemota.

Basic kushanda musimboti we switched kusada mota

A switched reluctance motor (Switched Reluctance Motor, SRM) of an electric vehicle has a simple structure. The stator adopts a concentrated winding structure, while the rotor does not have any winding. The structure of the switched reluctance motor and the induction stepping motor are somewhat similar, and both use the magnetic pulling force (Max-well force) between different media under the action of a magnetic field to generate electromagnetic torque.

Iyo stator uye rotor yeinochinja kusada mota inoumbwa nesilicon simbi sheet laminations uye inotora salient danda chimiro. Iyo stator uye rotor matanda eiyo switched kusada mota akasiyana, uye zvese zviri zviviri stator uye rotor zvine diki cogging. Iyo rotor inoumbwa neyepamusoro-magnetic iron core isina makoiri. Kazhinji, rotor ine matanda maviri pasi pe stator. Kune akawanda masanganiswa e stator uye rotor, izvo zvakajairika chimiro che stator nhanhatu uye mana rotor (6/4) uye chimiro che masere stator uye matanhatu rotor (8/6).

Yakachinja kusada mota imhando yekumhanya inodzora mota yakagadziridzwa mushure meDC mota uye brushless DC mota (BLDC). Masimba emagetsi ezvigadzirwa anotangira kubva kune mashoma watts kusvika kumazana ekw, uye anoshandiswa zvakanyanya muminda yemidziyo yemumba, ndege, aerospace, zvemagetsi, muchina uye mota dzemagetsi.

Izvi zvinotevera musimboti wekuti iyo magineti flux inogara yakavharwa munzira ine yakakura magineti permeability, uye inogadzira magineti yekudhonza simba kuti igadzire torque-kusada electromagnetic torque. Nokudaro, nheyo yaro yehutano ndeyokuti kusada kwemagnetic circuit kunofanira kuchinja zvakanyanya sezvinobvira kana rotor ichitenderera, saka iyo inoshandura kusada motokari inotora kaviri salient pole chimiro, uye nhamba yemapuranga e stator uye rotor yakasiyana.

Iyo inodzoreka switching wedunhu ndiyo inoshandura, iyo inoumba iyo huru dunhu remagetsi pamwe neiyo magetsi uye mota inotenderera. Iyo chinzvimbo detector chinhu chakakosha chechimiro cheiyo switched kusada mota. Inoona nzvimbo ye rotor munguva chaiyo uye inodzora basa rekushandura zvakarongeka uye zvinobudirira.

Iyo mota ine hombe yekutanga torque, diki yekutanga ikozvino, yakakwira simba density uye torque inertia ratio, inokurumidza kushandura mhinduro, kushanda kwepamusoro mukumhanya kwakakura, uye inogona kuona zviri nyore mana-quadrant control. Aya maitiro anoita kuti switched reluctance mota inyatsokodzera kushanda pasi pemamiriro akasiyana ekushanda emotokari dzemagetsi, uye imodhi ine mukana mukuru pakati pemotokari dzemagetsi. Iyo yakachinjika kusada mota dhiraivha inoshandisa yakakwirira-inoshanda chisingaperi magineti zvinhu kune yakachinjika kusada mota muviri, inova ine simba kuvandudza kune mota chimiro. Iyo mota nekudaro inokunda zvikanganiso zvekunonoka kutenderera uye yakaderera simba rekushandisa mune echinyakare SRMs, uye inowedzera chaiyo simba density yemota. Iyo mota ine torque hombe, iyo inobatsira zvikuru pakushandiswa kwayo mumotokari dzemagetsi.
