From industrial garbge I have salvaged a couple of motors mounted on the same plate, later I realized that I had only one motor because the other thing was a General Electric Control Plugging Switch. The stepper had no labels on it and was heavily painted with two coats of (doh) paint, one in blue the other one white. I have removed all the paint, unfortunately no labels or marks underneath.
Any suggestion on what to use as primer and paint?
Here are the stepper measures:
shaft diam 8 mm
shaft lenght 20 mm
motor diam 86 mm or 3.4 inches
motor length w/o shaft 110 mm or 4.3 inches
229 Ohms between each pair of leads
Original wires are colored : White_blue and white_yellow, white_green and white_red.
What I have found inside is a permanent magnet rotor and a stator with 16 slot in it.
So I guess 16/2 = 8 coils. Motor has 4 wires so I guess bipolar then is has 4 coils each winding, right?
How many steps would this motor do per revolution? 8?
Must have high torque then, isnt it?
