Abstract: An energy-saving or speed-increase control method for a hydraulic machine is disclosed in this invention, the characteristics of which includes a control plan to adjust pressure or flow amount of the machine for energy-saving or production efficiency increase; setting up working conditions as in input to said machine; inspection of working conditions and operational processes of the machine; updating demands in control plan based on the inspected working conditions and operational processes of a hydraulic machine; incorporating specific characteristics of individual elements in different working conditions and operational processes to coordinate with the control plan.

Abstract: A brushless electric machine includes a rotor and a stator. Each of the twin poles of the stator electromagnetic members corresponds to one of the two magnetic poles of the rotor magnetic assembles. Two radial component air-gaps are arranged between the stator and the rotor to separate the stator and the rotor. Axial component air-gaps axially corresponding are arranged between the stator poles and the corresponding rotor poles to separate the stator poles and the rotor poles. The stator wheel-shaped ring is partly surrounded by the rotor wheel-shaped ring.

Abstract: A magnetic force rotation device includes a rotor and a stator. The rotor is provided with a plurality of magnetic assemblies containing permanent magnet. The plurality of magnetic assemblies are arranged along the circumferential direction of the rotating shaft to form a wheel-shaped ring, and each magnetic assembly is provided with two magnetic poles. The stator is provided with a plurality of magnetically isolated electromagnets coaxially arranged. The electromagnets form a wheel-shaped ring around the rotating shaft, and each electromagnet is provided with paired poles. The wheel-shaped ring of the stator is at least party surrounded by the wheel-shaped ring of the rotor, so that each pole of the paired poles of the electromagnets of the stator corresponds to one magnetic pole of the two magnetic poles of the magnetic assemblies of the rotor respectively. Two axial component air gaps are provided between the rotor and the stator.
