What are the two commonly used types of power window lifting mechanism?

There are two transmission mechanisms of electric vehicle glass lifter: rope wheel type and cross arm type. Electric vehicle glass lifter is equivalent to the combination of the same type of manual glass lifter plus motor and reducer.

Therefore, a car equipped with a manual glass lifter can be changed to a motor to control the glass lifting after the corresponding motor and deceleration mechanism parts are installed. Electric window refers to the window that uses servo motor to drive the glass to lift, instead of the traditional rotating handle to lift the glass. So that the lifting of the glass becomes light, comfortable and automatic.

Extended data:

The electric window system is equipped with two sets of control switches: one is the master switch, and the driver can control the glass lifting of each window; The other set is a sub-switch, which is installed in the middle of each window and can be operated by passengers. The main switch and the sub-switch do not interfere with each other and can independently control the lifting of the window glass.

Two-winding series-excited DC motor has two magnetic field windings with opposite winding directions, one is called "ascending" winding and the other is called "descending" winding. When electrified, a magnetic field in the opposite direction is generated, which changes the rotation direction of the motor and makes the window glass rise or fall.
