Disc rotor air cooled D.C. motor |
摘要 |
A brushless direct current (DC) electric motor includes a rotor and a stator. The rotor has at least one disc mounted to a central shaft. The disc has an outer portion consisting of permanent magnets. The magnets are mounted with their direction of magnetization transversing through the disc. The stator includes C-shaped electromagnets which straddle the disc and are mounted with their magnetic poles aligned in coupling proximity to the poles of the permanent magnets in the disc. Position circuitry senses a position of the permanent magnets with respect to the electromagnets and then provides a signal based on the position to the electromagnets to cause the rotor to rotate.
