Title:
PERMANENT MAGNET SYNCHRONOUS ELECTRIC APPARATUS
Document Type and Number:
Japanese Patent JPH07194082
Kind Code:
A
Abstract:
PURPOSE: To enlarge the output torque, using a permanent magnet.
CONSTITUTION: Stators 2 and 3 are constituted of plural ones different in diameter, and each stator 2 and 3 is arranged so that the specified space 4 may be formed between the inside periphery of one stator 2 and the outside periphery of the other stator arranged next to each other. A rotor 5 is arranged so that the permanent magnets 5b and 5c may be positioned in the space 4 and that air gaps 7 and 8 may arise between the permanent magnets 5b and 5c and each stator 2 and 3. It follows that both sides of the magnets 5b and 5c are used twice, so larger torque and larger power than those of a conventional one can be taken out.
