Welcome to the forum.Hi... This is my first day on this site... I am looking at purchasing a porter cable 7518 router from an American Site on the Internet but i am now worried about Voltage problems... In South Africa we run on 220-230... Is this going to be a problem?
Finally, someone has it right!! Good job Mal!Frequency is not an issue in this case as the motor is a 'universal' motor and should be capable of handling the frequency difference. Univeral motor speed is dependant on voltage, induction motor speed is dependant of frequency.
Mike, the speed control modules use triac technology to prrogressively reduce the portion of the AC cycle that gets to the motor. There should not be an appreciable difference between feeding 50Hz and 60Hz to the controller, but they would not work with a DC supply and would be less efficient with supplies below about 30Hz. There is nothing in the controller that is so frequency dependant that it would be upset by a 20% variation in supply frequency, and the motors are capable of handling Dc to around 100Hz before the core material magnetic characteristics would come into play.Mal, are you taking into consideration the soft start/speed control module? My guess is it will be damaged and is $$$ to replace. The modules are very picky and can not be used with external speed controllers... so altering the htz may be a problem.
Hi MalThe voltage would be a problem, but could be solved with a large transformer (4000VA or 4KVA rating minimum assuming that the machine always is started off load). Expect the transformer to cost more than the router.
