What factors are related to the load capacity of a motorized roller shutter tubular motor?

The load capacity of a motorized roller shutter tubular motor is a key indicator of its performance, which is affected by a combination of factors.
First of all, the power of the motor directly determines its load capacity. The more powerful the motor, the greater the torque it can output, so that it can drive heavier and larger rolling shutter doors. For example, rolling shutter doors used in some large commercial places or warehouses need to be equipped with high-power tubular motors to ensure their normal operation due to their large door area and heavy weight. Generally speaking, motors with a power between 300W and 1000W are suitable for rolling shutter doors of different specifications and weights. The higher the power, the greater the load capacity.
The torque output characteristics of the motor are also an important factor. In addition to power, the change law of the motor's torque at different speeds affects its driving effect on the rolling shutter door. A motor with good torque output characteristics can provide a large torque at the moment of rolling door starting, overcome the static friction of the door body, and start the rolling door smoothly; during the operation of the rolling door, the torque can be adjusted according to the movement state of the door body to maintain a stable operating speed; when the rolling door is about to reach the closed or open position, the torque can be appropriately reduced to avoid damage to the door body due to collision.
The transmission efficiency of the motor has an indirect effect on the load capacity. A motor with high transmission efficiency can convert more electrical energy into mechanical energy, thereby outputting a larger effective torque under the same power input. The transmission system of the motor includes components such as gear sets and pulleys. The design, manufacturing accuracy and lubrication of these components will affect the transmission efficiency. For example, a motor with high-precision gears, high-quality grease and a reasonable transmission structure design has a higher transmission efficiency and a relatively strong load capacity.
The weight, size and material of the rolling door itself are also closely related to the load capacity of the motor. Rolling doors that are heavier, larger in area or made of special materials (such as thickened metal door panels) have higher load requirements for the motor. For example, aluminum alloy rolling shutter doors are relatively light, while steel rolling shutter doors are heavier. When selecting a motor, you need to match it according to the specific conditions of the rolling shutter door. In addition, the installation method of the rolling shutter door and the friction of the running track will also affect the actual load of the motor. Uneven installation, debris or rust on the track will increase the resistance of the rolling shutter door, thereby reducing the effective load capacity of the motor. Our company focuses on the research and development and production of tubular motors for electric rolling shutter doors. By deeply studying these influencing factors, we can provide you with motor products with precise load capacity matching to ensure efficient and stable operation of your rolling shutter door system.
