More Information
Summary:Provided is an Nd-based sintered magnet for a permanent magnet rotating machine and suitable for a permanent magnet rotating machine, given that the residual magnetic flux density of the permanent magnet will not decrease, coercivity will be high, the coercivity at the edge parts of the permanent magnet in particular will be high, and the magnet is not likely to be demagnetized even at high temperatures. L'invention concerne un aimant fritté à base de Nd pour une machine tournante à aimant permanent et convenant pour une machine tournante à aimant permanent, étant donné que la densité de flux magnétique résiduelle ne diminuera pas, que la coercitivité sera élevée, que la coercitivité au niveau des parties limitrophes de l'aiment permanent en particulier sera élevée, et que l'aimant ne sera pas susceptible de se démagnétiser même à hautes températures.
