Roller Door Motors – They’re Cool!
We don’t generally take much notice of garage door motors. We press the button and the door opens…and press it again and the door closes. You may think that there’s not much to them, but you’d be wrong.
Door opening mechanisms are very common now, but there was a time, not too long ago when door openers with garage door motors didn’t exist. With the invention of the car came the invention of the garage door opener.
The roller garage door came on the scene in the early 1920s. A little later that decade, the electric garage door opener was released – and now people didn’t have to get out of their cars to open the garage. When they were new on the scene, the roller door motors were operated by a pair of switches, one on a post in the driveway and the other inside the garage.
In the 1930s, two different types of wireless remote control came on the market, both activating the roller door motors wirelessly. These remote controls were actually built into the coachwork of the cars, as the devices were quite large and barely portable.
Trouble in the Neighbourhood
As garage openers became more popular suburbs became more dense, a major design flaw was uncovered – as many garages were in range of a single remote control. If your remote was on the same frequency as your neighbours, both doors would operate when it was pressed. This was quickly resolved by introducing coded signals for each garage.
The solution to this was to use fixed code pulses that were set on both the remote and opener unit, so even if two units used the same frequency they would only open if they heard the right code.
Modern Door Openers
The explosion of the Internet of Things (IoT) has meant that more and more devices are being connected to the internet. Roller door motors are not immune. The garage door is still operated by a remote control, but the job can be shared with apps on a smartphone – you can even open our garage door from half way around the world!
