Abstract
The utility model relates to a permanent-magnet alternating current generator which provides a technical proposal for solving that a slip-ring for generating poles, a carbon brush, an exciting winding and a jaw pole are arranged in the present generator. The utility model is characterized in that the both ends of an I-shaped rotor are provided with permanent magnets. The utility model has the advantages of simple structure, small size, large horse power, low failure rate and long service life, which is especially widely used in automobile industry and can save a large amount of energy resource for the country.
Description
The utility model relates to a kind of permanent magnet alternator.
Generator is to be provided with square coil in the centre of two different in nature magnets, square coil is made cutting magnetic line movement and is produced induced potential in the magnetic field that magnet produced, when constituting the closed-loop path, this induced potential and external circuit will produce induced current, the basic principle of Here it is generator.For line of motion coil generator, be provided with slip ring, carbon brush, field winding (simulating different in nature magnet) and the pawl utmost point in the termination of coil, be used to produce magnetic field, this electric generator structure compactness, energy output is big.But because this generator is provided with slip ring, carbon brush, field winding and the pawl utmost point that is used to produce the action of a magnetic field, part is many, complex structure, cost height, volume is big, useful life is short, install and keep in repair inconvenience.
The purpose of this utility model just is to provide a kind of slip ring, carbon brush, field winding and pawl utmost point of not needing, and permanent magnet is rotated in coil just can produce a kind of extremely simple permanent magnet alternator of alternating current.
For reaching above-mentioned purpose, the utility model is achieved in that and is wound with coil on stator, the rotor that is located on the rotating shaft is I-shaped, is provided with permanent magnet symmetrically at the two ends of I-shaped rotor, and permanent magnet is provided with for the opposite sex at two symmetry ends of I-shaped rotor.
The utility model has the advantages that: owing to removed slip ring, carbon brush, field winding and the pawl utmost point in the generator in the past, simple in structure, installation and maintenance are convenient, and failure rate is low, and volume is little, and manufacturing process is simple, and cost is low, long service life.
The drawing explanation:
Accompanying drawing 1 is that the utility model overall structure is cutd open and shown schematic diagram;
Accompanying drawing 2 is the utility model stationary part coil connection diagrams.
Now the utility model is described in further detail in conjunction with specific embodiments:
Do a circular shell (2) with metal, be provided with stator (4) in the circumference inside of housing (2), stator has been done groove in (4), coil is housed in the groove, both sides circle centre position at circular shell (2) is equipped with bearing (1,7), by bearing (1,7) rotating shaft (6) is housed, and rotating shaft (6) center fixed in housing (2) is equipped with I-shaped rotor (3), be provided with permanent magnet (5,8) at the two ends of I-shaped rotor (3), this permanent magnet (5,8) opposite sex is provided with.Be contained in three groups of coils in stator (4) groove, A phase, B phase, C are connected with external circuit three terminations mutually, and three ends are respectively by diode D in addition
1, D
2, D
3Negative pole connect into a node.When external force made I-shaped rotor (3) motion, because permanent magnet (5,8) rotation just produces rotating magnetic field, this rotating magnetic field just produced electric current in the coil in stator (4).
Claims (2)
1. permanent magnet alternator, it is to be made of housing (2), stator (4) and the rotor (3) that is located on the rotating shaft (6), on stator (4), be wound with coil, it is characterized in that rotor (3) is I-shaped, be provided with permanent magnet (5,8) at the two ends of I-shaped rotor (3).
2. a kind of permanent magnet alternator as claimed in claim 1 is characterized in that the set permanent magnet (5,8) in I-shaped rotor (3) two ends is an opposite pole.
