Hi Guys,
Hope an experienced motor winder can help me with a question. I have a 230volt/50HZ 2 speed single winding motor connected Y/YY. It has to be changed to 690volt 60 HZ with the same internal connections. The original 230volt windings have 8 turns per coil and a c.s.a. of 3.6 sq.mm. I calculated the 690volt/60HZ winding would need 20 turns per coil and a c.s.a of 1.44 sq.mm. Am I far off the mark & what would be the effect of the change on the nameplate full load amps? Thanks! |
