New unified theory of magnetic field modulation motor has new breakthroughs in mechanism, structure and process
Specifically, the new unified theory of magnetic field modulation motors has new breakthroughs in mechanism, structure and process, which can effectively solve the problems of low torque density, large cogging torque and poor product consistency of servo motors.
From the perspective of mechanism, based on the theory of dual-working magnetic field harmonic servo motor first established in the world, the magnetic field modulation non-overlapping winding servo motor topology and the developed magnetic field modulation non-overlapping winding servo motor analytical analysis and design technology The general motor design guidelines proposed by the research team have increased the torque density of related products by nearly 10% and the efficiency by 3%. From the perspective of architecture, the research team established a high-end servo motor key index consistency evaluation system, revealing the influence law of servo motor parts processing error on comprehensive performance, and proposed integrated electrical, magnetic, thermal, machine and material characteristics. The robust design method of servo motor provides a solution to the problem of poor consistency of product specifications in large-scale manufacturing. From the point of view of technology, the research team proposed a cogging torque reduction method involving the difference of the airspace level by revealing the influence of machining error and material dispersion on the cogging torque and the mechanism of action, breaking the existing tooth. The slot torque reduction method is highly dependent on machining accuracy and material consistency. The actual results show that the product cogging torque ratio is reduced to 0.59%, reaching the international advanced level.
