Abstract

The utility model provides a controller for a permanent magnetic synchronous pulling motor, which comprises a three-phase rectifier module, an IGBT module, buses, a contactor, a micro-panel, a capacitor, an absorption capacitor, a radiator, a fan, a fan frame, an enclosure and a shielded cable, wherein the IGBT module is arranged on the radiator; the buses are arranged on the IGBT module; a bakelite plate is clamped between a positive bus and a negative bus; the positive bus and the negative bus are drilled with large holes and small holes for mounting pins of the capacitor; the small holes are used for connecting the pins of the capacitor; an insulation washer is sleeved on each large hole for separating the buses from the pins of the capacitor; a pad which is made of pure copper and is used for making up the length difference caused by thicknesses of the buses and the insulation washers; and the capacitor is fixed in a hole of a capacitor bracket. The radiator is used as an installing foundation, and an electric element is arranged through the buses and the capacitor bracket, so the controller for the permanent magnetic synchronous pulling motor has the advantages of compact structure, small occupied space and small volume.

Description

A kind of permanent-magnet synchronous traction motor controller

Technical field

The utility model relates to a kind of traction motor controller, especially relates to a kind of permanent-magnet synchronous traction motor controller.

Background technology

At present, the internal components spatial placement and the mounting structure of permanent-magnet synchronous traction motor controller are of a great variety, but all owe rationally, cause existing permanent-magnet synchronous traction motor controller complex structure, and it is many to take up room, bulky.

The utility model content

The purpose of this utility model is to overcome above weak point of the prior art, and a kind of internal structure compactness is provided, and space hold is few, the permanent-magnet synchronous traction motor controller that volume is little.

The purpose of this utility model is achieved through the following technical solutions: it comprises three phase rectifier module, IGBT module, busbar, contactor, microcomputer plate, electric capacity, absorption electric capacity, radiator, fan and fan board, case, shielded type cable; The IGBT module is installed on the radiator, busbar is installed on the IGBT module, accompany the insulating cement plank between two positive and negative busbars, on two positive and negative busbars, be drilled with macropore, aperture that the electric capacity pin is installed, aperture is used for linking to each other with the pin of electric capacity, cover is useful on the insulation cushion that separates busbar and electric capacity pin on each macropore, and the liner of being made by fine copper that is used for the length difference that polishing causes owing to busbar and insulation cushion thickness is housed in the aperture of one of positive and negative busbar; Capacitor fixing is in the hole of capacitance bracket.

Preferred version: three phase rectifier module and contactor are installed on the radiator; The microcomputer plate is installed on the case, absorbs electric capacity and is installed on the busbar.

The utility model is owing to utilize radiator as the basis is installed, and by busbar and capacitance bracket installation electric component, makes permanent-magnet synchronous traction motor controller compact conformation, and space hold is few, and volume is little.
