Thanks for the information. To be honest I thought the 3phase motor would be better than the dc one.
I have a small chinese mill and I toasted either the motor or its controller by pushing the mill beyond its limits. The motor got very hot and suddenly the house rcd tripped and kept tripping each time I switched the mill on. I have taken the motor apart and there are no superficial signs of any shorting across the windings but need to look further. Also inspected the controller card and again no blackening or other superficial signs of shorting. I am not an electrical engineer so have come to a temporary stop with the fault finding. Anyway I gave that up when starting to consider using a 3phase motor. I had assumed that 3phase would be better and easier to control with regard to the speed. The controller card I have is JYMC 220B I which is varaible up to 170vdc I think for full speed, and the dc motor is a 600w type 91ZYT005. Both motor and controller are available but I thought that I would need to get a new controller anyway if I was going to alter the speed through emc. I do not know where to get a suitable card thats why I was opting for 3phase. So any help or advice would be much appreciated.
