Powering brushless DC motor via adapter (from socket)

For an indoor project where I need low power and slow rotation (<1000 rpm) but long operation hours I am seeking for a solution using a brushless DC motor which I can power from the socket via an adaptor (e.g. 12 V DC).

I did find brushless motors that I believe can do the job (such as https://hobbyking.com/en_us/3508-580kv-turnigy-multistar-14-pole-brushless-multi-rotor-motor-with-extra-long-leads.html?queryID=ba7aba075acf9279518dd814208df6c3&objectID=40499&indexName=hbk_live_magento_en_us_products) but my worry are the current requirements. Realistically speaking I cannot provide much more than 2 A via the adaptor, and the motors and most importantly the ESCs are all rated (and I expect designed) for higher currents. Hence My question is there is a way using alternative speed controllers (maybe not designed for RC planes) and or power the motor with very low voltages to avoid currents the adaptor cant provide?

What would you recommend?
