Abstract
The utility model relates to a driving type brushless direct current arc welding generator, comprising a front end cover, a stator coil, a rectifying control box, an excitation coil, a rotor iron core, a rear end cover and a fan. The generator is characterized in that the excitation coil is fixed on a separating sleeve in the middle of the machine cavity; the rotor iron core is separated into a front rotor iron core and a rear rotor iron core in the axial direction; the stator iron core is correspondingly separated into a front stator iron core and a rear stator iron core in the machine cavity; and the magnetic pole of the front rotor magnetic core and the magnetic pole of the rear rotor iron core are staggered. As the traditional electric brush and converter are saved, the spark cannot be generated, the structure is simple, the maintenance and servicing are convenient, and the fault rate is low. As the rotor does not discharge copper wire, the cost is greatly decreased, and the total weight is reduced by about 30%. Compared with the traditional arc welding generator, the utility model enhances the efficiency by about 5%, is easy to strike arc, and can decrease the spattering rate to 6.6%.
Description
Technical field
The utility model belongs to electric welding machine.
Background technology
Direct current arc welding generator sends the arc-welding electric current by driving arrangement (as Diesel engine, motor) drive and carries out work.Direct current arc welding generator low-voltage, big characteristics of current make it have welding performance preferably, and little owing to volume, mobile flexible, easy to usely have a bigger range of application.But in general, the structure of direct current arc welding generator is comparatively complicated, and its armature rotor will roll off the production line, and causes its cost height, the manufacturing process complexity.Owing to adopt commutator and brush to come rectification, commutation spark is big, easily produces fault simultaneously.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, cost is low, drive-type brushless direct-current arc generator for ease of maintenaince, the technical solution of the utility model as shown in drawings, it comprises front end housing, stator coil, the rectification control cabinet, magnet exciting coil, rotor core, commutator end bearing support bracket, fan, it is characterized in that fixing a spacer sleeve at the middle part in machine chamber, fixed excitation coil on spacer sleeve, rotor core and back rotor core before rotor core is divided on axle, preceding rotor core and back rotor core are arranged on the both sides of magnet exciting coil, stator core and back stator core before stator core also correspondingly is divided in the machine chamber, preceding rotor core magnetic pole staggers with back rotor core position of magnetic pole, with the induced electromotive force of compensation armature winding.220 volts of windings are set in stator core, 220 volts of power supplys outwards are provided.Form rotating magnetic field in again by the external force dragging motor under self-excitation exciting current situation, stator coil then becomes armature winding and induced electromotive force is exported welding current again after rectification.The brush and the commutator of traditional direct current arc welding generator saved in such setting, can not produce spark, also makes electric generator structure simple, is convenient to safeguard and maintenance that failure rate reduces, and has prolonged useful life.Simultaneously, because rotor does not descend copper cash, saved the raw material of some, greatly reduced cost, total weight has also reduced about 30%.Structural design of the present utility model makes the magnetic circuit height satisfy and closes that internal impedance increases.Major loop rectifier, change over switch, exciting current adjusting device etc. are set in control cabinet.When arc welder is worked, satisfy the needs of welding condition by armature reaction and adjustment exciting current.The utility model is raised the efficiency about 5% than existing arc generator, and striking is easy, and spatter loss coefficient can be reduced to 6.6%.
