Brushless motor stator with fitting position determining structure of circuit substrate |
摘要 |
A brushless motor stator is provided that may be applied to a plurality of types of motors having different rotational speeds, merely by providing one type of a circuit substrate. A pair of fitting convex portions that project radially outside of a virtual circle centering on a center line C are formed on one insulator divided body of a slot insulator. Three pairs of diagonally located fitting concave portions are formed in an inner circumferential wall portion surrounding a through-hole of a circuit substrate. The pair of fitting convex portions of the one insulator divided body are fitted in one of the three pairs of fitting concave portions. With this, a positional relationship between three hall elements and stator magnetic poles is selected, corresponding to the speed range of a motor to be used. |
