Automatic blind motors are primarily referred to as "tubular motors," as they are typically cylindrical and mounted directly inside the blind's roller tube. Based on their technical principles, they are classified into the following categories:
1. DC Tubular Motor
Working Principle: Driven by direct current (usually 24V or 36V safe voltage).
Main Features:
Safety Voltage: Low voltage, safer, especially suitable for home use.
Energy-Saving and Quiet: Relatively quiet operation and low energy consumption.
Battery-Powered: The biggest advantage is that it can be powered by a large-capacity lithium battery or solar panel, achieving true wireless installation without pre-installed wiring, making it ideal for retrofits.
Suitable for: Homes, apartments, villas, and other locations without pre-installed electrical wiring.
2. AC Tubular Motor
Working Principle: Driven by 220V AC power.
Main Features:
Powerful Power: Typically has greater torque, capable of driving heavier, wider, and larger curtains.
Requires continuous power: Must be connected to a mains power source, requiring a pre-installed power outlet or wiring near a window.
Noise: Generally slightly louder than a DC motor during operation.
Suitable for: Large-scale projects with pre-planned electrical circuits, such as office buildings, shopping malls, and hotels.
3. Mechatronic Tubular Motor
Working Principle: This design integrates a DC motor and an AC power adapter. The motor itself is DC, but it connects directly to 220V AC power via an internal or external transformer.
Key Features:
Balance of safety and convenience: It combines the smoothness and quietness of a DC motor with the convenience of an AC motor, which uses a household outlet. No battery charging is required.
Flexible Installation: No wiring is required like with a pure AC motor; any outlet is sufficient.
Suitable for: Homes or locations seeking high quality and convenience, with a power source near a window.
