The present invention makes full use of the vortex flow of responding on the secondary guide plate for guaranteeing, should make the equal in length of secondary guide plate width and main and auxiliary magnetic pole, can obtain maximum electromagnetic actuation force like this.
For reducing the loss of magnetic circuit itself, each main and auxiliary pole core and each magnetic pole iron core relatively can be formed by silicon steel plate stacking to powerful linear electric motors in the present invention; For simplifying production technology, can directly adopt the monoblock steel to make the small-power linear electric motors.
The commutation of motor itself can be finished by point driving switch, also can be finished by travel switch.
The present invention is made into to concentrate winding by distributed winding by the improvement to existing single-phase AC linear electric motor primary, makes the designs simplification of motor itself, and has simplified production technology, advantage with low cost, dependable performance that this motor also has.
