Motorized Blinds

Overview

Motorized blinds are roller shades that raise, lower and hold position under motor power instead of a pull chain. The shade fabric winds onto an aluminium tube driven from inside by a slim tubular motor, so there is no visible operator, cord or wand. Control is wireless, phone app, smart-home hub, schedule or handheld remote, which makes the product attractive both for convenience and for cord-free child safety.

How it works

The fabric winds on the Headrail Assembly, an extruded aluminium roller tube capped and bearing-supported at each end. Concealed inside the tube is the Tubular Motor: a brushless DC motor and planetary reduction gearbox whose output drives an adapter that grips the tube wall, so the whole tube rotates while the motor body is held still by a keyed crown.

Motion is commanded by the Control Board. Its microcontroller drives the motor through an H-bridge, reads a Hall-effect encoder to track travel and enforce the programmed upper and lower limits, and carries a combo radio that speaks Wi-Fi, Zigbee and BLE to apps and hubs. The blind hangs the Shade Assembly, the roller fabric with a weighted hem bar that keeps it flat and square, and runs from the Battery Pack, a protected 18650 Li-ion pack recharged over USB-C.

A Solar Charging Panel is offered as an option: a small monocrystalline PV cell on a window suction mount trickle-charges the pack in daylight, so a well-lit blind rarely needs manual charging. Day-to-day, the RF Remote gives up, down, stop and preset control on multiple channels, and the Bracket Set clips the tube end caps to the wall or window frame.
