Title:
PERMANENT MAGNET-TYPE ROTOR AND ELECTRO- MAGNETIC POWER MACHINE PROVIDED WITH IT
Document Type and Number:
Japanese Patent JPH0698488
Kind Code:
A
Abstract:
PURPOSE: To easily constitute a rotor by arranging a plurality of arched members formed of permanent magnets along the periphery of the rotor, while interposing spacer levers among each of the arched members and fixing each arched member and the spacer levers in an integral cylindrical shape by clamping rings. CONSTITUTION: The free ends of a plurality of magnetic arched members 4-7 disposed onto the engaging surface of a rotor body are connected by clamping rings 8, 12, and spacer levers 9 are installed among the adjacent arched members 4-7. The spacer levers 9 are formed in a trapezoidal sectional shape, and reaction resisting centrifugal force is increased among each arched member 4-7, on which the spacer levers 9 are abutted. Two projections 14' and an expanding slot 13 between the projections 14' are formed to at least one clamping ring 12, and the two projections 14' are brought near by the clamping ring 12, thus generating inward pressure loading in the radial direction to the spacers 9.
