Alpha A2217 Crown & Drive for Battery Motor

The Alpha A2217 Crown & Drive is an accessory designed for compatible Alpha battery-powered tubular motor installations.

Alpha identifies the A2217 specifically as “C + D for battery motor”, distinguishing it from the other crown and drive combinations within the Alpha motor accessory range.

The crown and drive form an important mechanical connection between a tubular motor and the roller tube in which it is installed.

Designed for Battery Motor Installations

Alpha’s rechargeable battery motors provide a convenient solution for motorising compatible blinds without requiring a conventional 240V motor connection at the blind.

Like other tubular motors, however, the motor still needs to correctly interface with the surrounding roller tube.

That’s where the A2217 crown and drive are used.

The components help connect a compatible Alpha battery motor to the appropriate roller tube so the motor can rotate the tube during operation.

What Does the Crown & Drive Do?

Although they’re relatively small components, the crown and drive are fundamental parts of a tubular motor installation.

The drive transfers rotational movement from the motor to the roller tube.

When the motor turns, the correctly matched drive engages with the roller tube and causes the tube to rotate.

The crown forms another part of the interface between the motor body and roller tube.

Together, the crown and drive allow the motor to function correctly within a compatible tubular blind system.

Matching the A2217 to Your Blind

The fact that the A2217 is designed for a battery motor doesn’t mean it should automatically be assumed to fit every roller tube used with a battery-powered motor.

The roller tube still needs to match the corresponding crown and drive configuration.

Alpha’s supplied product information for the A2217 doesn’t specify a particular roller tube diameter or internal profile.

For that reason, we recommend confirming your existing tube before ordering unless you already know your installation uses the Alpha A2217.

Replacing an Existing Battery Motor

If you’re replacing an existing Alpha battery motor, keep the original crown and drive when removing the motor.

Don’t discard them until you’ve confirmed the replacement parts.

The existing components can help establish exactly what was previously fitted to the blind.

Look for identifying numbers or markings and take clear photographs of the crown, drive and end of the roller tube.

Measure the Existing Roller Tube

If you’re unsure which Alpha crown and drive you need, measure the existing roller tube and inspect its internal profile.

Two roller tubes that appear similar externally don’t necessarily use the same internal configuration.

Our Match Your Existing Blind Tube to the Correct Crown & Drive guide explains what measurements and photographs are useful when matching an existing blind.

Providing a clear photograph looking directly into the end of the roller tube is particularly useful because it shows the internal profile that the drive needs to engage with.

Product Code A2217

For customers replacing an existing component already marked A2217, the Alpha product code provides the clearest reference when ordering.

For installations where the existing crown and drive aren’t identifiable, confirm the motor and tube configuration before purchasing.

Important Compatibility Information

Alpha describes the A2217 as “C + D for battery motor.”

The supplied information doesn’t specify a particular roller tube profile or individual battery motor model. Compatibility should therefore be confirmed before ordering rather than assuming the A2217 fits every Alpha battery motor installation.
