Abstract

A six-phase C-core reversible flux permanent magnet generator consists of a stator, stator poles, permanent magnets, rotor, and shaft. The stator is a ring-shaped plate or tube with a C-core design. Several stator poles are located along the inner edge of the stator. Six-phase copper windings are wound around these poles in a counterclockwise direction. Grooves within the stator poles accommodate the permanent magnets. The rotor is mounted inside the stator and consists of a plate with several protruding poles. A central hole is located on the rotor for mounting and securing to the shaft connected to the generator. This design creates a six-phase C-core reversible flux permanent magnet generator that offers high magnetic utilization, low manufacturing costs, and high efficiency in induced electromotive force, load voltage, and power output.

Claims (5)

1. A six-phase C-core reverse flux permanent magnet generator consists of the following components: stator (1), stator poles (2), permanent magnets (3), rotor (5), and shaft (7). The stator (1) is the outer part, shaped like a ring or tube in the form of a C-core, which is fixed to the wall or frame of the generator to prevent the stator (1) from moving while the generator is running. On the inner edge of the stator (1) there are a number of stator poles (2) that protrude from the stator (1) in a direction toward the center. Each stator pole (2) is spaced equally apart. Around the stator poles (2) there are copper windings wound in a counterclockwise direction to generate an induced voltage. Inside the stator (2) there are grooves to insert neodymium permanent magnets (3). These permanent magnets (3) are rectangular in shape and create magnetic field lines that flow out from the north pole of the permanent magnet (3). Inside the stator (1) is a rotor (5) mounted. The rotor (5) is a plate with several poles protruding around it. In the center of the rotor (5) there is a hole for inserting and securing to a long cylindrical shaft (7) connected to the generator. When the shaft (7) rotates, the rotor (5) rotates as well at the same speed. There is a distance between the ends of the rotor poles (5) and the ends of the stator poles (2) that prevents the two poles from touching. This has a specific characteristic: There are 25 poles for the rotor (5) and 12 poles for the stator (2), wound with copper windings in six phases: phase A1 (A1), phase A2 (A2), phase B1 (B1), phase B2 (B2), phase C1 (C1), and phase C2 (C2). 2. A six-phase C-core reversible flux permanent magnet generator according to claim 1, where the optimal number of copper windings is 105 turns. 3. A six-phase C-core reversible flux permanent magnet generator according to claim 1 or 2, in which the centers of the ends of each permanent magnet (3) make equal angles, i.e., 30 degrees, when the center of the shaft (7) is the reference center. 4. A six-phase C-core reverse-flush permanent magnet generator according to any one of the claims 1-3, in which the left and right edges of the stator poles (2) make an angle of 11.25 degrees to each other when the center of the shaft (7) is the reference center. 5. A six-phase C-core reversing flux permanent magnet generator according to any one of claims 1-4, in which the left and right edges of the rotor poles (5) are at an angle of 5.63 degrees to each other when the center of the shaft (7) is the reference center.
