Kana iyo mota iri mune inopindirana yekushanda mamiriro neanogara achitanga, kazhinji kutanga kuchaita kuti mota ive nekukanganisa kwakakomba pamhepo nekuda kweiyo yakakura ikozvino panguva yekutanga maitiro, uye mhepo inoputika ichapisa uye kuchembera kusungirira, uye kuvimbika kwemota kuchadzikira. Kunyanya kumamotor anotangwa zvakananga pamagetsi frequency, dambudziko rakanyanya, saka iyo insulation level yerudzi urwu rwemota inofanirwa kunge yakakwira, kazhinji isiri yakaderera pane Kirasi F.
Kune mamiriro ekushanda ane nguva shoma yekumhanya uye nguva refu yekudzikira, mota inogona kunge iine condensation, ndiko kuti, mushure mekunge mhepo yekufambisa yadzikiswa kubva pakupisa kwakanyanya panguva yekushanda, mhepo ichave yakanyorova nekuda kwekusiyana kwekushisa uye kudzivirira uye zvakatenderedza zvakatipoteredza. Kana iyo mota yakatangwa yakananga pasi pemamiriro ezvinhu aya, inogona kuita kuti kuvhuvhuta kwemota kuparadzwe nekuda kwekusashanda zvakanaka kwekudzivirira, kunyanya kune yakakwira-voltage mota, dambudziko rinogona kunge rakanyanya. Nechikonzero ichi, hunyoro-humbowo hwekudziya zvigadziriso zvave zvakajairika kune akakwira-voltage motors, uye vashandisi vemota vanofanirwa kuita inodiwa kubviswa hunyoro vasati vatanga mota.
Kune ma-high-voltage motors uye ma-high-power motors, nekuda kwemaitiro anokosha emuviri wemotokari uye rotor inorema, kudzivirira kutenderera kunofanira kuitwa nguva dzose panguva yekuiswa kwemotokari kudzivirira migumisiro yakaipa pakutakura system, kureva, deformation yekutakura maitiro ezvikamu nekuda kwekufa kwe rotor; dambudziko iri harisipo kuti arambe achitenderera motors, chero bedzi kutakura maitiro ekushanda achinyatsoongororwa uye kugadzirisa kwakakodzera kunoitwa.
