- A working model for studying the principle and operation of an electric motor.
The above apparatus and schematic are used for both DEM40 and DEM41.
The Stansi motor is set up identically to that in DEM40, but the knife switch is wired to provide a motor function plus "off" function and a generator function (DEM40). The brushes are arranged on the commutator (not on the slip rings).
The Cenco motor can be wired for shunt-wound operation or series-wound operation (armature and field windings in parallel or series).
