What is the difference between built-in and external fast rolling doors motor?

Fast rolling doors are one of the most commonly used industrial doors in many factories. According to the installation space and use needs, it is equipped with different types of motors, which are divided into four types: built-in, left-mounted, right-mounted, and front-mounted. Among them, left-mounted, right-mounted, and front-mounted are collectively called external. What are the differences between the two, and are the prices the same? See below for details.

The difference between built-in and external motor high speed roller doors

The main difference is the degree of heat dissipation and the space occupied. The detailed differences are as follows.

Built-in motor, installed and hidden in the box at the door, does not occupy side space, suitable for places with relatively limited space. However, the motor and bearings are covered inside the box, and the heat dissipation effect is slightly weaker.

The external motor is separated from the door box and needs to occupy a space of 50 cm to install, but the heat dissipation performance is better.

The prices of built-in and external motors are biased. The built-in motor is more expensive than the external motor, and the front motor in the external motor is more expensive than the left and right motors. There is not much difference between the top and bottom of the same brand. The standard configuration of fast rolling doors adopts the right-mounted motor. In the case of insufficient space, the left and front positions will be considered. If there is no space, the built-in motor will be used. The built-in motor has no protruding parts, which is relatively more beautiful and simple. As for other performances of the product will not be affected by the motor.
