Embodiment Construction

[0010] See figure 1 The permanent magnet welding generator of the present invention includes a stator 1 and a rotor 6. The rotor 6 is located inside the stator 1. Four three-phase windings 3 are arranged on the stator 1. The rotor 6 is embedded with permanent magnet strips 7 and E-shaped conductive magnets. Core 2, winding 3, sensor 4, permanent magnet 5, rotor shaft 8.

[0011] The stator core consists of 12 E-shaped conductor core unit openings evenly distributed inward on the ring. A conductor magnet is embedded between every two E-shaped conductor cores, that is, two adjacent E-shaped conductor cores. The permanent magnet 5 sandwiched between the conductor core constitutes the iron core teeth; the winding is wound in the slot of the "E"-shaped stator punched piece with silicon steel sheet, and the winding coil: the entire circumference of the E-shaped conductor core is evenly placed in the stator slot. Group independent three-phase welding windings, that is, four independent...

Abstract

The permanent magnet electric welding generator includes a stator with a circular cross section and a circular rotor. The rotor is located inside the stator. There are four three-phase windings on the stator, and 12 permanent magnets are evenly embedded in the circumference of the rotor; that is, in each A permanent magnet is embedded between two E-shaped magnetic cores in cross-section; the stator consists of 12 E-shaped magnetic core units with openings evenly distributed inward on the ring, and the two adjacent E-shaped magnetic core units One winding is wound in each stator slot, and four sets of independent three-phase windings are evenly placed in the stator slot of the E-shaped magnetic permeable core on the entire circumference, and a sensor for measuring the position of the rotor is also installed on the stator. The winding is the winding output of electric welding or power generation. The power supply of the welding machine can be provided by connecting the welding windings in series or in parallel after changing them to direct current through independent three-phase rectifiers.

Description

Technical field [0001] The invention belongs to the technical field of electric welding and generator manufacturing, in particular a dual-purpose equipment for rotor permanent magnet electric welding and generator. Background technique [0002] Although the permanent magnet synchronous generator has the advantages of simple structure, reliable operation, small size, light weight, high efficiency and high power density, it is used in flywheel energy storage, various high-speed machine tool spindle motors and sealed pumps, centrifuges, and compressors. , High-speed miniature hard disk drives and other fields have more practical advantages, and are considered to be the most promising bearingless motors. [0003] In the construction occasions where an internal combustion engine driven generator is required as an electric welding machine, especially the output of multiple sets of electric welding is an important function of the product, the existing products do not have this function. ...
