[0002] Currently, travel positioning systems for door and window motors worldwide are primarily implemented using either mechanical or electronic methods. Mechanical systems, typically consisting of a screw and contact switches, are widely used due to their simple structure, reliability, and relatively stable performance. Electronic positioning systems, as a supplement to mechanical positioning systems, are more widely used due to their compact size and low cost.

[0003] However, the current mechanical positioning system has the following disadvantages: large size, high cost, displacement due to mechanical wear of the screw rod and contacts after long-term use, and difficulty in adjusting the travel positioning system relative to the door and window motor.

[0004] However, the current electronic positioning system has the following disadvantages: it can work smoothly under normal system conditions. However, when the system loses power and the doors and windows move, the main control mechanism cannot find the upper and lower stop positions, causing the door and window motors to malfunction.

[0005] Therefore, the present application proposes a tubular motor with an encoder to replace the conventional mechanical positioning method and reduce the complexity of the mechanical positioning operation. Utility Model Content

When the tubular motor is installed, the positioning device side is generally installed against the wall, so it is more stable and not easy to break.
