Unsure which power adapter fits a small motion setup

While reworking a compact lifting unit for a home project, I noticed that the power supply I originally used can no longer keep the movement stable, especially under light load. The motor starts fine, but the motion drops in speed after a few seconds, which makes me think the adapter isn’t delivering consistent current. I’m not sure how to choose a replacement that will handle both startup demand and continuous operation, so any advice on selecting an appropriate power source for linear motion would be really helpful.

When I dealt with a similar issue, I found it helpful to compare current ratings and output voltage across different adapters, and the selection on https://progressiveautomations.com.au/collections/power-supplies designed to support various 12 volt dc actuators configurations made that much easier. Many setups that rely on stable AC-to-DC conversion avoid hesitation or speed drops when paired with the correct supply, and once I switched to a unit rated for continuous load, the motion in my project became completely steady.

From my experience, most performance issues in motion assemblies start with mismatched electrical components rather than mechanical faults. Checking the expected load, duty cycle and the power supply’s output range usually narrows the choices quickly. Once these factors align, the actuator tends to run predictably without hesitation or uneven travel.
