ʻO ke kumu nui o ka haki ʻana o kakaʻa uila ʻO ka insulation ka mea i hoʻokumu ʻia e ka resonance o nā capacitors a me nā inductors i hoʻokaʻawale ʻia ma ka laina hoʻopuka e hoʻopili ʻia i ka volta puka, a i ʻole ka hopena kiʻekiʻe o ka hoʻololi ʻana a me nā wili lōʻihi o nā transistors a me nā IGBT, a hiki i ka pālua o ka uila DC.
ʻO nā hopena i ka haki ʻana o ka insulation motor:
1. E hoʻohana i ka motika me ka ikaika insulation kiʻekiʻe.
2. Hoʻohui i kahikaʻa AC hoʻokuʻu ʻia (ʻo 3%) ka impedance.
3. Hoʻohui i ka inductance L, ka capacitor C, a me ka kānana R resistor.
4. Inā loaʻa kahi pilikia insulation, e ʻike ʻia ka pilikia i ka manawa pōkole.
Pehea e ho'āʻo ai i ka insulation o ka ʻO Simo Motorua wawahiia? E hoʻohana i kahi haʻalulu 1000 volt. Inā ua wāwahi ʻia, ʻaʻole ʻo ka pale insulation. E nānā mau i ka laina kelepona a hoʻopau i nā pōʻino huna i ka manawa. ʻAʻole pono e hoʻonui ʻia ka laina kelepona no ka manawa lōʻihi, a pono e hahai ʻia nā kaʻina hana.
