Summary:The utility model discloses a permanent magnet direct current motor stator, which comprises a base, a plurality of N-pole iron cores and a plurality of S-pole iron cores, the root parts of the N-pole iron cores and the S-pole iron cores are arranged at intervals and are fixed on the base, the root parts of the N-pole iron cores and the S-pole iron cores are sleeved with demagnetizing coils, and the head parts of the N-pole iron cores and the S-pole iron cores are fixedly provided with magnetic steel. And the plurality of demagnetizing coils are connected through coil connecting wires. According to the permanent magnet direct current motor stator, when a magnetic field formed after the demagnetizing coil is electrified is opposite to a magnetic field formed by the magnetic steel in polarity, a main pole magnetic field can be weakened, and the purpose of improving the rotating speed of a motor is achieved. 本实用新型公开了一种永磁直流电机定子，包括：机座、多个N极铁芯和多个S极铁芯，多个N极铁芯和多个S极铁芯的根部间隔布置且均固定在机座上，N极铁芯和S极铁芯的根部均套设有去磁线圈，N极铁芯和S极铁芯的头部均固定有磁
