永磁电机、转子及其永磁体
摘要：
本发明公开了一种永磁电机、转子及其永磁体，永磁体的中间部分的抗退磁能力高于所述永磁体两端部分的抗退磁能力。本发明提供的永磁体，由于永磁体的中间部位的退磁程度大于永磁体的两端部分，通过使永磁体的中间部分的抗退磁能力高于永磁体两端部分的抗退磁能力，使得永磁体各部分的退磁更均匀，进而减少了永磁体局部退磁的情况发生，提高了永磁电机的整体抗退磁能力，进而提高了永磁电机的使用寿命。
摘要（英）：

The invention discloses a permanent magnet motor, a rotor and a permanent magnet thereof. The anti-demagnetization capability of the intermediate portion of the permanent magnet is higher than that of the both ends of the permanent magnet. According to the permanent magnet provided by the invention, since the anti-demagnetization capability of the intermediate portion of the permanent magnet is higher than that of the both ends of the permanent magnet, by making the anti-demagnetization capability of the intermediate portion of the permanent magnet higher than the anti-demagnetization capability of the two ends of the permanent magnet, the demagnetization of various parts of the permanent magnet is more uniform, thereby reducing the occurrence of partial demagnetization of the permanent magnet, raising the overall anti-demagnetization capability of a permanent magnet motor, and further improving the usage life of the permanent magnet motor.
