Ki te whakatauritea ki te motuka DC me te motuka asynchronous, ko ngā āhuatanga hangarau matua o te motuka DC Kore Paraihe ko:

1. Ka whiwhihia ngā āhuatanga whakahaere o te motuka DC mā te whakahaere hiko. He pai ake te whakahaere me te whānuitanga tere whānui.

2. E hiahiatia ana ngā mōhiohio urupare tūranga rotor me te taraiwa hurihuri hiko maha-wāhanga.

3. Ko te tikanga, ka taea e te motuka AC te mahi i te tere teitei me te kore e mura, e memeha rānei te paraihe me te commutator. He tino pono, he roa te ora mahi, ā, kāore e hiahiatia he tiaki.

4. He nui te mana o te motuka DC kore paraihe, kāore he ngaronga o te rotor me te wera, ā, he tino pai te mahi: ki te whakatauritea ki ngā raraunga, ko te pai o te motuka asynchronous 7.5 kW he 86.4%, ā, ko te pai o te motuka DC kore paraihe he rite te kaha ka eke ki te 92.4%.

5. Me whai wāhanga whakahaere hiko, he nui ake te utu katoa i te motuka DC.

E rua ngā momo motuka matua e whakamahia ana i roto i te pūnaha AC: te motuka whakapūmau me te motuka tukutahi aukume tuturu. Ka taea te wehewehe i te motuka tukutahi aukume tuturu ki te motuka tukutahi aukume tuturu EMF sinusoidal back (PMSM) me te motuka DC kore paraihe EMF ngaru tapawhā (BLDCM) i runga i te kaupapa mahi rerekē. Nō reira he rerekē te iahiko taraiwa me te aratau whakahaere.

Ko te EMF o muri o te motuka tukutahi aukume tuturu sinusoidal he sinusoidal. Kia pai ai te whakaputa taipana o te motuka, me sinusoidal te ia e rere ana i roto i te takai motuka. Nō reira, me mōhio te tohu tūranga hurihuri tonu, ā, ka taea e te inverter te whakarato i te ngaohiko sinusoidal, te ia rānei ki te motuka. Nō reira, me whakamahi te PMSM i te ngaohiko teitei, i te ia rānei. He tino uaua hoki te taumira o te encoder tūranga, te resolver rānei.

Kāore e hiahiatia ana e te BLDCM he pūoko tūnga taumira teitei, he māmā noa te taputapu urupare, ā, he tino māmā te raupapa whakahaere. Hei tāpiri, he pai ake te whai huatanga o te papa aukume āputa hau o te ngaru trapezoidal BLDCM i te ngaru sinusoidal PMSM, ā, he teitei ake te kaha o te BLDCM i te PMSM. Nō reira, kua nui haere te aro ki te tono me te rangahau i te motuka DC kore paraihe aukume tuturu.
