| Zusammenfassung: | PURPOSE: To hold speed detecting magnets and a speed detecting element for the detection of rotational speed of a rotor using a simple structure, and prevent damage to the speed detecting magnets and stator coil ends. CONSTITUTION: A speed detecting element 11 is installed on a bracket 13. Projections 6 are formed on the end faces of vanes 4 on a rotor end ring 3 in a position corresponding to the speed detecting element 11. Doughnut-shaped speed detecting magnets 1 are fit and crimped onto the projections 6. |
