Abstract:
The present invention discloses an R-T-B-M-C sintered magnet and a method for manufacturing the R-T-B-M-C sintered magnet from an R-T-B-M-C alloy powder including the lubricant. The present invention also discloses an apparatus for manufacturing the R-T-B-M-C sintered magnet from the R-T-B-M-C alloy powder including the lubricant. The apparatus includes an alloy powder feeding mechanism for distributing the R-T-B-M-C alloy powder including the lubricant, a filling mechanism including a mold for receiving the R-T-B-M-C alloy powder including the lubricant, a press mechanism for compressing the R-T-B-M-C alloy powder including the lubricant and a stacking mechanism for storing the mold including the R-T-B-M-C alloy powder including the lubricant.
