Brushless DC motor slotted tooth lamination |
摘要 |
A stator lamination allows the construction of a d.c. motor having minimum cogging torque and maximum horsepower. Each stator lamination comprises a ring of ferromagnetic material having a number of (e.g., eight) inwardly-extending integral teeth. Each tooth has a radially-inwardmost surface with side end terminations, the side end terminations of adjacent teeth being spaced from each other to define a first set of slots. A V-shaped radially-outwardly extending slot is formed in each of the radially-inwardmost surfaces between the side end terminations, to define a second set of slots (if eight teeth are provided, a total of sixteen slots are provided). The teeth have thin stems which may be wrapped with a large amount of copper wire material. The laminations are disposed in a concentric stack with each lamination skewed with respect to an adjacent lamination.
