Method and apparatus for connecting straight line motor secondary side conductor and secondary side iron core

Abstract

The invention relates to a connection method of the hypo-side conductor of the straight line motor and the hypo-side iron core and its equipment, the hypo-side conductor of the straight line motor and the hypo-side iron core used the external pressure pattern to be fixed fixedly, the hypo-side conductor through the bolt compact installment directly fixed on the hypo-side iron core base from the out surface of the hypo-side conductor. The fix installment of the hypo-side conductor includes the hypo-side conductor, the hypo-side iron core and the base. The hypo-side conductor covers out of the hypo-side iron core. The inter surface of the hypo-side conductor cling with the base of the hypo-side iron core. The outface of the hypo-side conductor press side joint with the compaction bolt installment, and the compaction bolt installment fixed on the base of the hypo-side iron core.

Description

technical field [0001] The invention relates to a component structure of a motor, in particular to a secondary side conductor structure layout of a linear motor secondary. It is mainly used for motor traction of subway vehicles. Background technique [0002] The linear motor subway vehicle is one of the most advanced urban rail vehicles in the world today. It is named after the linear motor traction technology. The linear motor drive uses the thrust generated by the electromagnetic effect between the linear motor and the induction plate (secondary) as the traction force or electric braking force of the train, which has nothing to do with the adhesion between the wheels and rails. Compared with the traditional rotary motor subway vehicle, the linear The electric motor subway vehicle is a non-adhesive-driven subway vehicle, which has many advantages such as low engineering cost, low operating cost, low noise, strong climbing ability, strong curve passing ability, and simple ...

Problems solved by technology

Of these two structural forms, the riveting type has the disadvantage of being inconvenient to replace, so it is rarely used; while the internal pressure type is currently the most widely used structural form at home and abroad. This structural form is to process the secondary conductor into a special shape (see attached Figure 1), and then The secondary side conductor is fixed on the upset seat from the inside by bolts (see attached Figure 2)

The processing technology of the secondary conductor of this structure is complicated, the processing is difficult, and the installation is not very convenient, so it is very difficult to implement in our country, and it is necessary to improve this
