Working tooth flux as motor flux, on tooth to analyze some amount of magnetic induction intensity and find some related to tooth magnetic flux density and volume of mutual relations, so that in the design of the brushless motor used as the basis for judgment and design analysis. The following motor magnets, the relevant data of the stator and stampings and tooth some analysis on the relationship between magnetic flux density and the motor magnetic flux density, and some relevant conclusions: (1)Plate is changeless, tooth magnetic flux density is almost the same length, (2)Change the tooth width and tooth width and tooth is inversely proportional to the magnetic flux density, the error is very small (3)Magnetic steel material change, Bz is proportional to the Br, error within the design coincidence rate < Br > (4)Under the condition of tooth magnetic flux density of unsaturated, plate material change, little change tooth flux density (5)Plate magnet steel shape scaling up of motor magnetic circuit performance, air gap magnetic flux density and magnetic flux density of teeth is almost the same (6)Plate other change shape, tooth flux density effect is not very big (7)Table stick type magnetic steel change shape, tooth magnetic flux density and motor Kt, same as the rated working point
