This paper analyzed the nonclassical potential symmetries FokkerPlanck equation.And these nonclassical potential symmetries were determined by considering a generalized potential system rather than the natural potential system. The new symmetries of these given PDEs and auxiliary potential systems were obtained. Furthermore, the corresponding exact solutions can be obtained by using the above symmetries. The solutions have extensive application value for further researching the physical phenomena described by FokkerPlanck equation.
