窗户电动机/调节器组件是什么？

窗户调节器通常具有十几个组件，可以在整个窗户的整个升高或降低过程中以非常特定的方式向上或向下移动。这些组件都在两个唯一的组件中一起使用：剪刀样式窗口调节器和电缆操作的窗口调节器。

There are scissor-style window regulators that operate like a giant pair of scissors inside your door. They’re usually almost flat when your window is all the way down and in a near perfect X when the window is all the way up. You can look at a scissor style regulator as having several thick pieces of steel that keep the window in place. It’s sturdy, but requires a strong motor that often wears out before everything else.

Cable-operated window regulators use a near vertical cable to help the window get into the right position. It’s a more compact design that puts less stress on the motor. But it is also more susceptible towards breaking due to the increased stress that the pulley and cable must harness to raise and lower your window. In most cases, a cable operated window regulator is composed of one thick piece of metal with a pulley and wire attached to it -- along with a more compact motor.

电动机旨在承受窗户的一定数量的凸起和较低。当调节器有助于将窗户固定在适当的位置时，电动机提供了使窗户准确保持所需的力所需的力。
