I know nothing you are speaking about here, so sorry if my questions are out of scope. Please let me know if I'll have to do anything extra except just using a motor in my application. To lock and unlock a bike at the park point I've used 24V DC motor. I power it from 12V and it takes 10mA (all accessible for me 12V motors I have tested needed 50mA or more). To lock/unlock takes about 1s. The expected use it 5 lock and unlock operations a day so totally 10s per day. Unfortunately that motor can be taken out and still functioning ;-) Will I have to do some tests of that motor (except testing if it works well) ? I hope the answer is NO (YES looks stupid for me in such application). And what if that tests fail ? I can imagine situation when this motor (24V/20mA ~ 12V/10mA) designed to take low current and give low power has low efficiency, and other (12V/50mA) has high efficiency. Do in such situation I'll have to use this effective one (the time for lock/unlock will be the same) ? My task was to allow 100 such park points work 48h powered by 12V 7Ah accu and each mA counts.
