4、iciencyreason:more winding space bigger magnet wire dia.& more turns lower resistance & higher efficiency the same lengththe same power consumption off40% increasetorque rises 30% by current risingthe same lengththe same current27% fallpower consumption off by30%lower vibration & lower noisethere is

5、 friction between the winding and stator lamination,this will make vibration and noise,injection technique will make them combined together to avoid any friction. higher precision and smoothnesshigher assembly precisionstep angle accuracy(right):test result of step angle accuracy:moons 2.5%skc 4-5%l

7、f normal 3-phase motor:3-phase motor: only 2/3 resistance works 2-phase motor:100% resistance worksrunning torque of 3-phase motor is 30% less than 2-phase motor under the same lengthadvantages of 3-phase modular injection motor: higher torque: a. stator and rotor are longer(saving the space from 2

8、end caps) b. higher current under the same power consumption (bigger size magnet wire dia. and more turns.saving the space from screw assembly holes and longer stator) so the same length motor of 2-phase vs 3-phase,the torque are similar. lower temperature rise: a. lower power consumption than same

9、torque normal motor b. bigger heat-past area because of longer stator lamination. c. heat-past speed is must faster than past by air.3-phase driver ica package solution for 3-phase motorms3000a: 1ic for 1motorms3000b: 1ic for 2motors3-phase motor+3-phase driver ic=moons package solution23hm motora t
