What is the difference between the tubular motor and the chain motor of the shutter door?
1. Tubular motor has a strong waterproof performance and high precision electronic travel limit, as well as sensitive resistance stop function, which is not the traditional chain type motor, chain motor power is larger, external, tubular motor power small in the big shaft inside the installation.
Save space, telescopic door motor fixed on the bottom plate, general telescopic door motor and shutter door chain motor is 370w or 420w, tubular motor is relatively small. Remote control can be universal, first crystal vibration should be the same, such as 433mhz, second password should be the same, so can be universal.
2. The tubular motor is composed of stroke part, motor part and deceleration part, and three parts are placed in the circular tube to work, hence the name. Working principle: the stroke part controls the upper and lower limit of the motor; Motor part is responsible for motor operation; The decelerating part adopts the planetary decelerating part to reduce the motor speed and increase the output torque at the same time.
Working principle of the chain motor: the chain motor is in the bearing chain, between each section plus a higher bearing roller accessories to carry goods. And the chain is roller to the track rolling slide.
The roller on the chain is in rolling contact with the track, the friction resistance is small, the power loss is low and can bear a heavier load. Its bearing capacity and support strength, chain size and roller size, material are related, and roller material is generally steel, but some occasions to reduce the noise, and the use of abrasion resistant engineering plastic manufacturing.
