Permanent-magnet stepping motor

摘要: The stator assembly of a PM stepping motor having two-phase structure in which two stators arranged along the circumferential direction such manner that respective pole teeth are intermeshed together combined back to so as phase-shift at an electrical angle 90°. field rotor magnet is face small distance, and magnetized on its surface with plurality alternating N- S-poles preset width not matching tooth pitch each stator.
