Abstract

The invention discloses a current-adjustable multipolar permanent magnetic electric welding machine set, comprising a generator and a rectifier. The generator comprises a stator winding; three winding connection terminals of the stator winding are connected to three input terminals of a three reactors; each reactor is provided with a sliding contact for adjusting a reactive value; the three sliding contacts are connected to three input terminals of the rectifier; the output terminal of the rectifier outputs current for welding; the front end of the sliding contact is in lap joint with the reactor; the rear end of the sliding contact is installed on a support rod which is vertically arranged; the lower end of the support rod is connected to a spline which is meshed with a gear installed on the output shaft of the motor. The output terminal of the reactor is connected to three output terminals; the spline is driven to move up and down by the motor to change the number of turns of the reactor of the access circuit and to achieve the goal of adjusting output welding current. The adjustment is easy and the change of the output current is continuous. The invention realizes current fine adjustment, satisfies various welding requirement and has wide application range.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to an adjustable current multi-pole permanent magnet electric welding unit. Background technique [0002] At present, the electric welding unit uses an excitation generator, which has a large volume and a cumbersome structure.
