A new type of jogged magnetic transmission system is presented

which combine motor and reducer. This system is simple structure

manual programming

high transmission ratio

low cost and high reliability. The FEM model and mathematical model were established according to the analysis of structural feature and operational principle

and magnetic vector potential strategy （MVP strategy） was adopted. The static performance is get

then the effect of magnetic potential

air gap and material on the transmission performance are analyzed. The merits and faults of this system are presented after comparing this system with existing motor product.
