TH19748Y - Double-Salian permanent magnet generator - Google Patents

Abstract

A double-saline permanent magnet generator consists of a stator, rotor, permanent magnets, copper windings, and a shaft. The stator, the stationary part, is located around the outside of the generator and is lined with neodymium permanent magnets along its circumference. The magnetic field lines emanating from the magnets are parallel to the circumference, and the magnetic poles alternate. The stator poles are arranged as protruding poles between the centers of the permanent magnets, and copper windings are wrapped around these protruding poles. The generator shaft is attached to the rotor, which also has protruding poles similar to the stator. This type of generator is used to produce electricity from renewable energy sources, such as wind turbines or hydroelectric turbines.

Claims (6)

1. A double-saline permanent magnet generator consists of a stator (1), permanent magnets (3), copper windings, a rotor (5), and a shaft (7). The stator (1) is the outermost part of the generator and is in the form of a ring-shaped sheet or tube, which is fixed to the walls or frame of the generator to prevent the stator (1) from moving while the generator is operating. On the inner edge of the stator (1) there are a number of poles (2) which are in the form of protrusions extending from the stator (1) in a direction toward the center. Each pole (2) is spaced equally apart. Around these poles (2) is a copper winding wound counterclockwise to create an induction voltage. On the inner edge of the stator (1) between these poles (2) are grooves made to fit a rectangular neodymium permanent magnet (3). The permanent magnet (3) acts to create magnetic field lines which flow out from the north pole of the permanent magnet (3). The rotor (5) is mounted inside the stator (1) and is a plate with a number of poles protruding around it. The center of the rotor (5) has holes for fitting and securing to the shaft (7), which is a long cylindrical shape. When the shaft (7) rotates, the rotor (5) rotates as well at the same speed. There is a distance between the ends of the poles of the rotor (5) and the ends of the poles (2) of the stator (1) such that the two ends do not touch. This is characterized by the number of poles (2) of the stator (1) being 18 and the number of poles of the rotor (5) being 15, or the number of poles (2) of the stator (1) being 24 and the number of poles of the rotor (5) being 20. The centers of the ends of each pole (2) of the stator (1) are at equal angles. Let the center of the shaft (7) be the reference center. and the center of each rotor pole end (5) makes equal wide angles when the center of the shaft (7) is set as the reference center. 2. A double-saline permanent magnet generator according to claim 1, in which the stator pole width (1) is of a suitable size, i.e. the left and right edges of the stator poles (1) make an angle of 11 degrees to each other when the center of the shaft (7) is given as the center of reference. 3. A double-salian permanent magnet generator according to claim 1 or 2, in which the width of the rotor poles (5) is of a suitable size, i.e. the left and right edges of the rotor poles (5) are at an angle of 11 degrees to each other when the center of the shaft (7) is given as the center of reference. 4. A double-salian permanent magnet generator according to any one of the claims 1 - 3 in which the center of each stator pole (2) is at an angle of 20 degrees or 15 degrees when the center of the shaft (7) is the reference center. 5. A double-salian permanent magnet generator according to any of the claims 1-4 in which the center of each rotor pole end (5) is at an angle of 24 degrees or 18 degrees when the center of the shaft (7) is given as the reference center. 6. A double-Salian permanent magnet generator pursuant to any one of claims 1-5, where the optimal number of copper windings is 100 turns.
