Tubular Motor Insertion Into Tube:

The picture below shows the tubular motor prior to insertion inside 6061 aluminum tubing. Note the marking of the position of the drive shaft adapter with the grease pen. This is where you would drill a hole if you want to insert a locking screw. The crown adapter is visible on the right hand side (black) and you can see how far it fits into the end of the tube, leaving only the end flange visible.

To assemble the unit, slide the motor into one end of the tube; use your fingers to compress the tines on the drive adapter so that it can slide in; you will need to exert some pressure to slide it in. One trick we learned is to wet the rubber drive adapter with isopropyl alcohol; this will make it easier to slide in, and it will evaporate quickly, making a nice tight fit.

You may need to file some rubber off if the tube is smaller, or add some duct tape if it is bigger.

PLEASE NOTE:
Do not use a hammer to pound it in, damage will occur!

You may want to add a locking screw to make sure there is no slippage. Prior to insertion, drill a hole through the tube, insert the motor, then drill a pilot hole into the adapter inside and insert a locking screw. Make the hole in the tube as big as the screw head so that it ends up being flush with the tube surface, so not to disrupt the fabric. You could also use a tapered head type of screw and countersink the hole to make it flush.

Try and make it so that the screw penetrates the larger tine on the drive adapter, so that it has some material around it to hold on to. You could also apply some thread locking adhesive to ensure that the screw will not work its way out over time.

A self-tapping metal screw works well as a locking screw, and it does not have to be very big (but don't forget to drill a pilot hole). Note that it should not be too long either, or it will hit the metal drive shaft after passing through the drive adapter.

Depending on the type of tubing you use, the adapter may be slightly on the large size. In this case, use a flat file to gently remove some of the rubber material in order to reduce the diameter (left), until you can push it in.

Be careful not to use a bench grinder, or other power tool that can remove a lot of material very quickly - you may remove too much. You want it as tight as possible, while still being able to push it in by hand.

If the selected tubing has a larger inside diameter than the motor drive adapter, wrap some tape around the drive roller to build up the diameter of the drive shaft adapter. Heavy duty duct tape is a good choice.

Don't put too much on, just enough to take up the slack when you slide it in. If you put too much on, it will make it too tight, and may push the tape off the drive adapter. Use tape to build up the diameter of the crown adapter so that it also has a snug fit.

When you slide the motor housing in, push it all the way until the lip of the crown adapter flange is flush with the end of the tube.

Keep in mind that if this is one of our radio equipped tubular motors, there will be a short length of heat shrink tubing on the wiring as it comes out of the motor. The heat shrink sheath covers the radio antenna wire, which should be arranged so that it is not touching any other metal piece, or you will diminish the range considerably.

Under normal conditions, these receivers have a considerable range, and are capable of receiving commands from our multi-channel remotes from anywhere inside a typical home. Unlike IR (infrared) remotes, the RF signal also passes through walls without any difficulty, and the remote does not have to be pointed at the motor.

Also, note the 'settings' hole in the picture (left), at the top of the motor end cap. The motor assembly needs to be mounted so that the hole is accessible. You can also see the crown adapter flange (black) that is left exposed after the motor has been fully inserted into the tube.

If this is one of our radio-equipped motors, when you press the button inside the hole with a small screwdriver, it triggers the 'handshake' electronics that allow you to assign this motor to a particular motor on one of our multi-channel remote controls. The travel limits on the radio equipped motors are set entirely by the remote control, so you do not have to touch the motor for that purpose.

If this is one of our non-radio motors, the button inside the hole is used to set the travel limits.
