Embodiment Construction
[0011] In the figure, the fixed half shaft (4) is concentrically fixed with the rear end cover, and the fixed half shaft and the front end cover support the concentric rotation of the output half shaft (8). One end of the three sets of combined wheel-moving brackets (2) made of non-magnetic stainless steel is supported by three one-way bearings (7) arranged in the same direction on the fixed half shaft (4) in the same direction in a clockwise direction, one-way The other end is supported by three one-way bearings arranged in the same direction on the output half shaft (8) to lock the reverse rotation of the output half shaft (8), so that the output half shaft is passive or active Beyond turning. Three pairs of identical, sector-shaped permanent magnets (12) are symmetrically fixed on each center line and on each cover combination wheel moving support (2), and the polarity of each pair of sector-shaped permanent magnets (12) magnetic pole faces (14) is in phase with the left an...

The invention discloses a mixed-arranging type wheel power repulsion permanent magnet direct-current motor. Same-polarity magnetic pole surfaces of a plurality of primary magnetic poles of the motor are adjacent, fan-shaped permanent magnets in an opposite repulsion state are on the same plane, are in the same direction at the periphery and are independently rotated in turn in sequence; magnetic poles of rotation-assisting electromagnetic poles with plugs are in concentric exceeding ration in side surface; opposite repulsion magnetic fields between the magnetic pole surface are laterally shielded one by one, so that each pair of magnetic pole surfaces gets close one by one, and is locked by a magnetic coupling device; after the rotation-assisting electromagnetic poles are electrified to separate from the permanent magnet poles, the combined fan-shaped permanent magnet magnetic poles recover repulsion acting force; the magnetic coupling device is electrified to release repulsion magnetic acting force stored between the fan-shaped permanent magnet magnetic poles, so that kinetic energy output is formed on the rotary shaft. Compared with a conventional wheel power repulsion motor, the permanent magnet motor utilizes the magnetic energy of the permanent magnets more sufficiently, so that reluctance torque of the permanent magnets is lowered to a greater extent, electric energy is saved to a greater extent, and an energy-saving rate is increased.
Description
Technical field [0001] The invention relates to a power-saving permanent magnet DC motor. Background technique [0002] Between the patent number: 2013107441091 invention and creation title: "A wheel-driven repulsive permanent magnet DC motor" in the permanent magnet motor power-saving technical solution: "In the motor casing, each pair is symmetrically fixed on the center line of the circle. Multiple pairs of wheel-moving permanent magnets with the same shape, equal volume, and the same polarity of the magnetic pole faces are in a lateral repulsion state on the same plane or the same circumference, and the edges of adjacent magnetic pole faces coincide with each other. The rotation drives the output semi-axis and the non-magnetic flywheel fixed on the semi-axis to rotate concentrically; corresponding to the pole surface of the wheel-moving permanent magnet, it is symmetrically fixed on the center line of the circle to the non-magnetic flywheel The metal magnetizer in the t...
