Re: CIM Voltage and Motor Suggestions

Very interesting discussion so far...
I would like to add that the output power of a motor is not only a function of input current but also of the available field in the magnet structure. At some point, the magnetic field developed by the electrical structure may exceed the permanent magnets. At this point, no additional speed or power will be available and all excess electrical input is turned to heat. Without some testing at these extremes, we can not determine a point at which this will occur. Please remember that the resistance of the motor windings and brushes are also affected by heat which will change performance. Unfortunately, as nice as this motor is for a two minute match, it is not designed for anything approaching continuos duty, included are heat dissipation, brush life and bearings.
