Ma motors angapo amtunduwu amatha kuyendetsedwa osati ndi magetsi amtundu wa DC okha, komanso ndi magetsi osasunthika. Ndipo ili ndi kamphindi kakang'ono ka inertia, magwiridwe antchito abwino, komanso kusintha kwakukulu kwa katundu. Ndiwoyenera makamaka pamakina owongolera omwe amafunikira kuwongolera liwiro, kuthamanga kwambiri, kukhazikika kwachangu, komanso kuyankha tcheru.
Ma motors angapo amtunduwu amatha kuyendetsedwa osati ndi magetsi a DC okha, komanso ndi magetsi okhazikika. Ali ndi kamphindi kakang'ono ka inertia, magwiridwe antchito abwino, ndipo amatha kupirira kusintha kwakukulu kwa katundu. Ndiwoyenera makamaka pamakina owongolera omwe amafunikira kuwongolera mwachangu, kuchita bwino kwambiri, kukhazikika kwachangu, komanso kuyankha tcheru.
Amagwiritsidwa ntchito kwambiri pamakina osiyanasiyana oyendetsa, monga mphero yachitsulo, coiler, compressor ya shuga, ng'anjo ya simenti ndi makina otulutsa mphira ndi pulasitiki.
