Abstract
The present disclosure provides direct drive system, belongs to drive systems field. The direct drive system includes: base and slide spaced from the base, the base being provided with stator assembly, slide being provided with rotor assembly; rotor assembly including a first magnetic conductor and a plurality of magnets arranged on the first magnetic conductor; the stator assembly including second magnetic conductors and windings spaced on second magnetic conductors, windings being arranged opposite magnets, and magnetic field generated by windings covering magnets to generate electromagnetic thrust with magnet to drive the slide to move along sliding direction. Windings are spaced, and coils in each group of winding are cooperatively energized to drive rotor assembly with magnets to operate, which effectively reduce consumption of coils, reduce material costs, reduce heating quantity, reduce energy consumption of direct drive system, to improve operation efficiency of direct drive system.
