Sir TophamHatt Posted October 29, 2019 Share Posted October 29, 2019 (edited) It's an older Roco Class 80.0 that's been in my project drawer for a very long time. I can't particularly ease the motor out but it's clearly touching the metal chassis. Edited October 30, 2019 by Sir TophamHatt Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted October 29, 2019 Share Posted October 29, 2019 The cast block the motor is in doesn't appear to be split. A look at the underside would be likely to be more informative. If there are wipers bearing on the wheelbacks than it isn't split chassis 1 Link to post Share on other sites More sharing options...
RMweb Gold Hroth Posted October 29, 2019 RMweb Gold Share Posted October 29, 2019 That the casing of the motor is in contact with the chassis doesn't always mean that its a split chassis. The case will be a support for the motor magnets, the brushes will be mounted on the insulated plastic ends. It's more informative to know where the motor brushes are connected. Are they wired to opposite sides of the chassis (=split) Is one motor brush wired to the chassis and the other to insulated wipers against the wheels on one side (=not split) Are both motor brushes wired to insulated wipers against the wheels on one side (=not split) Of the above cases, 1 is a split chassis arrangement (you should be able to see an insulating arrangement between the two halves of the chassis), 2 is the traditional live chassis used in the past, eg Triang locomotives and 3 is the method used on most modern models. Hope thats helpful! 1 Link to post Share on other sites More sharing options...
