Compared with the prior art, the utility model has the advantages of simple structure, small size, light weight, large capacity, reliable operation, high efficiency and energy saving; the utility model can be made into serial products, wherein, the power of which is from 100W to 500W and the voltage can be 14V or 28V; no spark generates in operation, and other electric appliances can not be disturbed.

Description

The double plate permanent magnet generator

The utility model relates to a kind of permanent magnet generator, specifically a kind of double plate permanent magnet generator.

The generator that present automobile, tractor charge a battery is an excitation type, but because complex structure, parts are many, many parts are difficult for processing, fragile, and the easy loose contact of current-carrying part, poor reliability, production cost height easily produce spark during work, disturb other electrical equipment, in addition, existing permanent magnet generator capacity is less, also has the shortcoming that does not satisfy automobile, tractor charge in batteries needs.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and a kind of simple in structure, volume is little, capacity is big, reliable, energy-efficient double plate permanent magnet generator is provided.

The technical solution of the utility model is such: this double plate permanent magnet generator, it is the structure that adopts a p-m rotor and two disc type stators, two disc type stators are arranged at the both sides, front and back of p-m rotor respectively, p-m rotor produces axial magnetic field in two sides, when engine drive belt pulley makes the p-m rotor rotation, coil on two disc type stators of axial magnetic field cutting of both sides, and produce induced potential therein, outside connection load will have electric current output, and the mechanical energy of engine is transformed into electric energy.

The coil of two disc type stators can in parallel or series connection.

The utility model has following advantage compared to existing technology: 1. simple in structure, volume is little, and is in light weight, and capacity is big, reliable; 2. can become series of products, power can be by 100W-500W, and voltage can be 14V or 28V; 3. efficient energy-saving, no-spark produces during running, can not disturb other electrical equipment.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the structural representation of the utility model double plate permanent magnet generator.

Embodiment: the double plate permanent magnet generator is the structure that adopts a p-m rotor and two disc type stators, two disc type stators (1,3) be arranged at the both sides, front and back of p-m rotor 2 respectively, remaining structure is identical with the permanent magnet generator that a Daepori leads to, p-m rotor produces axial magnetic field in two sides, when engine drive belt pulley 4 makes the p-m rotor rotation, two disc type stators (1 of axial magnetic field cutting of both sides, 3) coil on, and produce induced potential therein, outside connection load will have electric current output, and the mechanical energy of engine is transformed into electric energy, and power output is two generator sums.

Claims (1)

1. double plate permanent magnet generator, include disc type stator, p-m rotor and belt pulley (4), it is characterized in that: it is to be made of a p-m rotor (2) and two disc type stators (1,3), two disc type stators (2) are arranged at the both sides, front and back of p-m rotor (1,3) respectively.
