ok cool.....

when i done my first ROTARY, i use MAXON A-MAX 110123, 22 mm diamter 15 volt, cost about 45 euro something like that that i remeber well, stupid motor, i think MAXON was very good but no way

i test the machine like this, put needlestube rubber bands, and make the machines run costantly at 12 volt (motor was 15 v) and like this the motor absorb 0.18/0.20 ampere, mush less than what they say on the specific,

well after 3 hours approximatly the shaft of the motor come out, broke, i try 4 time consecutive with 4 new motor, all broke in this way, i contact MAXON becouse i cant belive that a SWISS motor broke like this after 3 hours, any 1 dollar chinese motor cant broke after 3 hours consecutive and a SWISS motor broke, and i always get some strange reply from them, and never ever they replace me the motors, so i stop use MAXON
