So chances are that most others are not stronger either -- you don't need 50 Nm for running a windshield wiper. But if someone has a good source of such motors (which includes datasheets), I'd like to check that out. The other thing is that we may have difficulties securing several hundred of the same type from a typical car wrecker :) Thanks, Gerhard -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
