This is a test with a sandwitch pulse motor and 2 single coils wounded similarly and connected in serie. What this test shows is that at a constant load and speed, if i retire one of the coil (but this coil is always connected but not activ) the speed of the rotor stay constant but the amperage almost doubles.(from 38 to 75 ma)
There is surely something to do with the BEMF but how ?
