Te motini o raro
Ko te motini o raro he momo taputapu keri i whakawhanakehia mo te huri i te hiko waipēhi ki te hiko miihini na roto i te waahanga hiko e hangaia ana e te stator me te rotor. Ko te nuinga o nga wa ka wehea nga motuka ki nga momo e rua, ko te riu kotahi (1/2) me nga motuka maha (N / N + 1), i runga i te nui o nga riu o te stator me te rotor. teitei ake te taipana putanga ko, vice versa.Ko te nuinga o nga wa e whakamahia tahi ana nga motuka me nga poro o te cone, nga paraka taimana me era atu i roto i te mahi keri, penei i te ahunga me te keri poutū, te keri whakapae, te whakatika i te rereke, te coring, te reaming, te sidetracking, etc.
Ka taea hoki te whakauru i a tatou motika downhole ki te waahanga hiko roa. Te whakataurite ki nga motuka noa, ka tino piki ake i roto i te taipana whakaputa me te kaha, e awhina ana ki te whakanui ake i te tere o te urunga. Ka taea te whakatika i te koki piko mai i te 0 ki te 3 nga nekehanga (i waenga i te 0 ki te 3 nga nekehanga) i roto i te papa rig me te kore he arapa. Ka tohu tika te koki ki te taha teitei o te mata taputapu.
He mana motuhake to tatou motika o raro, penei i te rakau honohono anti-friction. Maamaa te whakapai ake i te kaha o te motuka me te whakanui ake i te waa rere.
