joeqsmith49 Posted March 7, 2012 Share Posted March 7, 2012 This next video shows me making one last pull with the Green Machine Pro. This motor has made several pulls and the it's brass plain bearings are starting to fail. You can hear it in the video. You can watch how the arm moves as the load is applied. The little 66 Watt motor is no match for my dyno as it ends it's life in a total meltdown. http://www.youtube.com/watch?v=ip2BtaHqnFw Quote Link to comment Share on other sites More sharing options...
joeqsmith49 Posted March 7, 2012 Share Posted March 7, 2012 Who makes a good motor? Something with ball bearings and 100 - 200 Watts continious output power. I can use up to 1.9" diameter on the motor mount. Quote Link to comment Share on other sites More sharing options...
joeqsmith49 Posted March 9, 2012 Share Posted March 9, 2012 Appears one winding may have been weak after heating and broke. Showing the brake. There are cracks in the copper. Quote Link to comment Share on other sites More sharing options...
joeqsmith49 Posted March 9, 2012 Share Posted March 9, 2012 Brushes were fine. Looks about 0.025" dia wire and 26 turns. Had some 0.030 and was able to get 13 turns on it. Made a couple of pulls with it and the new winding really changed the performance. Motor will now make 45 Watts at 10,000 RPM. At 20,000 RPM it will make 62 Watts. Not an electric motor guru but seems less turns pushed the power range up and lost torque. Sounds pretty poor at 25,000 RPM with the out of balance and bushings going on it.

joeqsmith49 Posted September 20, 2014 Share Posted September 20, 2014 https://www.youtube.com/watch?v=X5uIXf0YuaU https://www.youtube.com/watch?v=E2lkUI1Vtl0 I ran into a snag with Google and lost my videos. Uploaded the two videos I had saved of my toy dyno. Here is the last larger home made one. Not doing closed loop controls with it yet but getting some real good numbers off it.
