Abstract

The invention provides a rotor of permanent magnetic arc welding generator, composed of a shaft, an aluminum yoke, a magnetic block, and an annular press cover, wherein the cylinder surface of the aluminum yoke is provided with 12 T-type grooves, 12 rectangle magnetic blocks are embedded into the T-type grooves to be pressed and fixed via the annular press cover and a press cover bolt. The invention resolves the hard installment problem of magnetic block. The aluminum yoke is provided with three ventilation holes screwed on axis, to rotate and generate axial airflow to cool the rotor, thereby effectively improving the efficiency of arc welding generator.

Description

technical field [0001] The invention relates to a generator rotor for permanent magnet arc welding. Background technique [0002] Traditional arc welding generators mostly adopt the transmission mode of motor rotor and generator rotor integrated, which has complex structure, large volume and high cost. The rotor winding generates the rotor magnetic field under the action of the excitation current, and the generator outputs the arc welding current. The use of rare-earth permanent magnets to replace the rotor coil windings to generate output current is a long-disclosed technical solution, but it is mostly used in power frequency generators. Due to the high temperature generated when the arc welding generator works with high current, the output power and service life of the generator are reduced. [0003] The technical problems solved by the present invention are to overcome technical defects and provide a high-frequency permanent magnet arc welding generator rotor with relia...
