, pound cycle to be 11ms every time, the place that provides in standard of electric machinery park.

Electric machinery declines from 460.0mm altitude to what originally to go up on armor plate on maple board (500.0mm×500.0mm×20.0mm)

With GM

From on the watch can see our country car rises with door window fall implement the level that the occupation standard of electromotor basically used foreign advanced company, if press this standard design, make, experiment, its product can achieve international advanced level.

6.Think with the proposal

In recent years, take electronic model block control to prevent clip to develop in abroad according to window electric machinery very fast, a few medium, high-grade cars of domestic had begun to choose, but still count an import completely. Home shakes aircraft production manufacturer should accelerate window report to cooperate with manufacturer of module of domestic and international electron, make electric machinery matchs to it, in order to get used to the development of this kind of tide. Aim at foreign technology to develop trends at the same time, those who develop low electromagnetism interference, miniaturization shake window electric machinery.
