Use different size wire in electro clutch?
The coil in an industrial electromagnetic clutch (connecting the flywheel to
the drive mechanism) has gone open-circuit. So it is being rewound by a motor rewind shop. I was just informed that the original wire was about 12 ga. (maybe slightly larger; original was metric) but it was rewound using 10 ga. Should I be worried about this change in wire size? Will this change the magnet's strength significantly? The current draw? Here's the original schematic: http://i47.tinypic.com/2lkpt94.jpg "F" is the clutch coil. The machine isn't currently wired to mains so the clutch's exact operating voltage isn't known. The transformer voltage that supplies the rectifier bridge seems to be 32 v (per label on the schematic). Here's photos of the clutch. (The coil is imbedded in a groove in the metal cylinder.) :: http://i48.tinypic.com/2hnyqll.jpg http://i46.tinypic.com/2nlg5de.jpg http://i49.tinypic.com/24pjaqu.jpg http://i45.tinypic.com/29bdduw.jpg http://i47.tinypic.com/291c7cw.jpg Will this change in wire size cause me troubles? Thanks, Dave |
