Three anomalous transport phenomena are theoretically predicted in a vibrational motor, where an additional temporally periodic signal plays analogous role of noise in a Brownian motor. By manipulating the amplitude of the additional periodic signal, absolute negative mobility, negative nonlinear mobility and differential negative mobility are observed. The parameter regimes for the abnormal transport behaviors are identified. Coexisting attractors are responsible for these anomalous transport phenomena.
