A thorough investigation was conducted for the proof process of Heisenberg’s famous inequality. It is apparent that any particle, no matter a classical or a quantum particle, as long as in wave motion, its dp always has an upper limit and a lower limit, which results in the product of dp and dx has both upper and lower limits. The Heisenberg’s inequality is nothing to do with measurement accuracy but related to energy conservation. A new deduction method for a spinning electron revolving on an orbit around a nucleus was developed based on our recently developed theory of spin vector in motion behaving particle-wave duality. The electron’s motion equation is same as Schrodinger equation while with a different energy constant j which is related to the spin vector’s motion features such as the mass of the object, the spin period and revolution period, the orbit shape and size. The new deduction process of Schrodinger equation will help explain the dilemma of the quantum mechanics.
