特徴とする永久磁石同期機の着消磁機構。 N and S poles of an even number of permanent magnet field poles are provided alternately on the outer peripheral surface of the rotor core, and the N and S field poles are arranged alternately.
In a permanent magnet synchronous machine in which a brake winding is arranged between the pole field magnetic poles, a short circuit piece is connected to both ends of the brake winding, and a connecting piece is installed between the adjacent short circuit pieces to form a short circuit ring, the permanent magnet When magnetizing or demagnetizing the magnet field poles, remove every other connecting piece from one shorting ring, remove every other connecting piece from the opposite shorting ring, and remove every other connecting piece from the opposite shorting ring. Make sure that the missing parts of the connection pieces are alternate, and connect the shorting piece → brake winding → shorting piece → connecting piece → shorting piece → brake winding → shorting piece → connecting piece → shorting piece → brake winding → shorting piece → connection A magnetizing/demagnetizing mechanism for a permanent magnet synchronous machine, characterized in that a series circuit is formed, and a field pole is magnetized or demagnetized by energizing or reversely flowing a direct current through the series circuit.
