Bilateral electric excitation magnetic flow of nonoverlapping winding tooth's socket type switches linear electric motor

The utility model discloses a bilateral electric excitation magnetic flow of nonoverlapping winding tooth's socket type switches linear electric motor, including one elementary with two secondary, have the air gap between elementary and secondary. Contain a mkn elementary cell elementarily, m is the number of phases, and k is a positive integer, and n is the motor unit number. Every elementary cell includes two cross magnetic materials, and during excitation winding set up the groove in the middle of the elementary cell, armature winding set up in the groove of elementary cell both sides, andthe winding encircles in elementary cell yoke portion. The secondary magnetic materials who is tooth groove structure is located elementary both sides. Compared with the prior art, the utility model,have that winding overhang length weak point, winding zero lap, the loss of electric machine are little, power density and efficient, advantage such as the normal direction pulling force is little, befit for being applied to n
