Problems solved by technology

Its disadvantages are: 1. Since the magnet is located inside the magnet holder, the plastic is not easy to cover the inside of the magnet holder during injection molding, and the fixation is not firm
2. In the follow-up process, it is necessary to magnetize the magnet steel. Since the magnet steel is located inside the magnet steel fixing frame, its exact position cannot be seen from the outside, so it is easy to fail to magnetize effectively

Embodiment Construction

[0013] Referring to the accompanying drawing 1, the magnetic steel fixing frame 1 for the magneto rotor shown in the embodiment of the present invention is a ring-shaped member with a plurality of grooves 5 on its edge, and there are two positions for fixing the magnetic steel 2 in the fixing frame. There is a fixed card 3 on the side, and a plurality of windows 4 are also opened on the fixed frame. They are all located on one side of each magnet 2 and in the middle of the ring, and the position of each window corresponds to the position of each magnet 4. Magnetic steel 2 is fixed on the magnetic steel fixed frame 1 by fixing card 3, and plastics easily enters from each window 4 and is covered with the inside of magnetic steel fixed frame during injection molding, and magnetic steel is fixed reliably. Each window accurately indicates the position of each magnet during magnetization, which is convenient for effective magnetization.

[0014] The above drawings and embodiments ar...

Abstract

The invention relates to a magnetic steel fixing frame for a magnetor rotor. The magnetic steel fixing frame is an annular part, a plurality of grooves are formed in the edge of the magnetic steel fixing frame, and fixing clips are arranged on the two sides of the position where magnetic steel is fixed in the fixing frame. A plurality of windows are further formed in the fixing frame, the windows are arranged on one side of each piece of magnetic steel, and the positions of the windows correspond to the positions of all pieces of magnetic steel. The fixing clips enable the magnetic steel to be fixed reliably. In injection moulding, plastics can easily enter and fill up the inside of the magnetic steel fixing frame through all windows to fix the magnetic steel well. Meanwhile, the windows accurately indicate the positions of all pieces of magnetic steel, so that effective magnetization is facilitated.

Description

technical field [0001] The invention relates to the technical field of magneto, in particular to a magnetic steel fixing frame for a rotor of a magneto. Background technique [0002] A magneto is a small alternator that uses permanent magnets to generate a magnetic field, and is the ignition power source in the ignition system of a gasoline engine. The magneto ignition system is composed of switches, ignition coils, breakers, capacitors, distributors and safety discharge devices, etc. It generates high-voltage electricity and distributes it to the spark plugs of each cylinder. Most of the magneto adopts the structure of rotating magnetic steel, the magnetic steel is installed on the rotor, and other components are respectively installed on the internal combustion engine. When the magnetic steel rotates, the primary coil induces an electromotive force (called primary potential), and a current (called primary current) is generated when the breaker contacts are closed. When th...
