Electrical machines as provided herein can include a shaftless rotor with an annular array of permanent magnets; and a stator with an annular ferromagnetic core and a plurality of electromagnetic inductors about the ferromagnetic core. The stator is located adjacent to and substantially co-axial with the shaftless rotor; and a fluid thrust bearing located in an axially planar gap between the stator and the shaftless rotor. The annular array of the permanent magnets of the shaftless rotor and the annular ferromagnetic core and electromagnetic inductors of the stator have a magnetic attraction that provides a co-axially centering force on the shaftless rotor.

A generator is horizontally arranged in each plane central portion of horizontal frame bodies of a support frame body which is framed with the upper and lower horizontal frame bodies and a plurality of support poles, and a vertical main shaft of a vertical shaft rotor is integrally connected and supported between rotation shafts vertically facing each other of the upper and lower generators without using bearings to cooperatively move.

A specially designed rotary actuator comprising a sealed container and a piston rotor located in the sealed container. The piston rotor divides the sealed container into a first space and a second space having different pressures. The first end of the piston rotor faces the first space and includes a plurality of first bores, and the second end of the piston rotor faces the second space and includes a plurality of second bores. The depth of the first and second bores is less than the thickness of the piston rotor. Each of the first and second bores comprises a first portion and a second portion, wherein the surface area of the first portion is greater than the surface area of the second portion.

A power converter having a boosting mechanism with a multi-shaft vertically stepped turbine includes: a shaft sleeve, a water inlet end base, an outer sleeve, a plurality of first stepped turbine units, a plurality of first shaft rods, a plurality of second stepped turbine units, a plurality of second shaft rods and a third shaft rod. The first stepped turbine unit is located above the second stepped turbine unit. The second stepped turbine units and the first stepped turbine units rotate in opposite directions. During a drainage process, water flows move in opposite directions and collide with each other to increase a water pressure. Due to the increase in the water pressure, rotational speeds of the first stepped turbine units and the second stepped turbine units increase, and rotational speeds of the first shaft rods and the second shaft rods correspondingly increase.
