Problems solved by technology

[0003] The present invention provides a new type of structure in order to solve the problems of inconvenient replacement and inspection of the rotary rectifier module of the existing brushless synchronous generator or although the rectifier module can be conveniently replaced by placing the rectifier module externally, but the center of the rotating shaft needs to process a through hole and the process is complicated. brushless synchronous generator
This avoids the problem that the existing structural connection line passes through the shaft center and the drilling process of the shaft center is complicated

Embodiment Construction

[0014] A brushless synchronous generator, including a main generator 1, a rectification device composed of a rectification module 4 and an exciter 3, a rotor bracket 2 is fixed on the rotor shaft inside the base of the main generator 1, and an exciter is fixed on the rotor bracket 2 For the rotor of machine 3, rectification module 4 of rectification device installed radially and vertically is fixed on the end face of rotor support 2 facing the air inlet of machine base end cover; the two output leads of rectification device composed of rectification module 4 are insulated Threaded copper rods 5 that pass through the rotor bracket and are processed at both ends. Like the existing brushless synchronous generator, the rotor bracket 2 is fixed on the bushing 6 on the rotor shaft, so the copper rod 5 passes through the bushing 6 while passing through the rotor bracket 2 . The copper rod 5 is sheathed with an insulating sleeve 11 and an insulating pad 12 to realize insulation passin...

Abstract

The related brushless synchronous generator for train and rail vehicle comprises: a main generator fixed a rotor frame on shaft inside, the excitation rotor fixed on the rotor frame, the radial vertical rectifying module on the end surface opposite to the inlet of the base bracket, and two copper rods as rectifying module output wire with thread on ends. This invention introduces convenience to the replace of rectifying module, and simplifies technology for opening hole on center of shaft.

Description

technical field [0001] The invention relates to a brushless synchronous generator, in particular to a relatively high-speed brushless synchronous generator used on railway locomotives and railcars. Background technique [0002] In the existing brushless synchronous generator, a rectifying device and an exciter are fixed on the rotor shaft of the main generator. When used in the field of railway locomotives, due to axial space constraints, the main generator, rectifier and exciter are arranged according to the relationship of energy flow, that is, the rectifier is discharged between the main engine and the exciter (as shown in Figure 1), and the rectifier The rotating rectifier module in the device is inconvenient to replace and inspect. If the module needs to be replaced, the motor must be dropped off and disassembled, which is labor-intensive and time-consuming, and the maintenance cost is high. For this reason, some existing brushless synchronous generators have rectifier ...
