The invention discloses a push type passive motor. The motor consists of a liquid vessel, a liquid, a thrust generator, an energy converter, a displacement delimiter and auxiliary components. By utilizing pressure difference, gravity, buoyancy and a limit technology, each stress point of a rotating part is distributed according to a preset state to ensure that actuating arms of the stress points are not the same, the state is dynamically maintained, and the rotating part is subjected to durable action of asymmetric torques to endlessly rotate; and because the generated energy is far more than the energy consumed internally, power can be constantly output. According to the appearance size, namely 11*10*2m, external output power 12.8kw can be realized so as to bring tremendous, clean, environment-friendly and economical energy supply for human society and inestimable social and economical benefits can be generated.
