Document Type and Number:
Japanese Patent JPH0736693
Kind Code:
B2
Abstract:
PURPOSE:To reduce a concentrated magnetic field without increasing the end section length of a rotor by arranging coils inserted into each slot by stages so that the end-section axial direction intervals of the coils are increased relatively in the coils nearer to a magnetic pole and reduced relatively in the coils further from the magnetic pole. CONSTITUTION:In a superconducting field-winding, a section between coils nearest to a magnetic pole is brought to 1.20Xl/(n-1) or more on n(where n>=4) coils and end-section length of (l), a section between the next coils to 1.05Xl/(n-1) or more, and they are reduced by stages, and a section between coils furthest from the magnetic pole is brought to 0.80Xl/(n-1) or less, a section between the coils far from the magnetic pole next to 0.95Xl(n-1) or less, and the sum total among all coils is brought to (l) in the end-section axial direction intervals of the coils in arrangement of the coils. Consequently, the magnetic flux concentration of the coil nearest to the magnetic pole is relaxed, and the magnetic flux concentration of the coil furthest from the magnetic pole is increased. Accordingly, the maximum magnetic flux concentration of each coil is levelled, and maximum magnetic flux density as the whole field- winding is minimized.
