This is a very simple generic DC electric motor with two electromagnetic coils. It has internal and external parts, so this model can be used to show the parts and operation of a DC electric motor.
The parts found in the engine are:
Natively the engine was modeled in Blender, and was exported to the following formats: blend (Blender Render and Cycles Render), obj, fbx, 3ds, dae.
Along with the model I include two very simple textures of iron plates and copper wires, to be used in the electric motor.
