Thread: Varibale Speed for Drill Press (Induction motor?)
20/01/2011 22:27:55
Following all the previous comments about changing the speed of a single phase motor by putting a choke (resistance) etc in series with the supply - which is a none starter due to the large power loss this would intoduce, apart from being very dodgy without the required Electrical knowledge. Why don't you tackle the job the easy way and make a bigger pulley(s) to reduce the speed, much easier and a lot safer too. The other Electrical solutions would be very costly to implement.
