Embodiment 1

[0033] Select high-quality silicon steel sheets containing a moderate amount of silicon to punch out 48-slot motor winding off-line punches with an outer diameter of 20 cm, an inner diameter of 15 cm, and an outward notch, and laminate them to form a stator core with a thickness of 3.5 cm. The inner diameter is The iron plate is clamped to facilitate the installation of the fixed shaft, which is beneficial to install the motor on the fixed frame. The motor can be prepared as a 500W / 24V two-pole three-phase AC rated output power variable frequency generator, and the lower coil winding of the stator Line, after calculating the diameter of the wire and the number of turns per slot from the relevant power calculation formula, the coil is rolled off in double-layer stacked winding with a span of 1-2 slots. Each pole and each phase occupy four consecutive slots, and the three phases alternate according to the phase. The number of pole pairs is accurately off-line, and finally connect...

Embodiment 2

[0036] About the method of exempting the iron core frequency conversion generator from silicon steel sheet punching:

[0037] The newly designed frequency conversion generator has completely changed the traditional way of manufacturing the iron core of the motor by punching out the groove shape with silicon steel sheet and then laminating it into the motor core. Power output for power supply.

[0038] 1). Preparation of fixed shaft:

[0039] Use carbon knot steel to cut out the corresponding space on the machine tool according to the design drawing, including the end cover positions with permanent magnets attached to both ends, the bearing positions, the fixed winding coil positions and the magnetic push-pull component positions. The shaft is hollow so that the power supply wire can be led out to have a channel.

[0040] 2). The method of making the generator coil winding:

[0041] According to the rated output power of the generator, the number of motor phases, output volt...

Embodiment 3

[0050] At present, domestic solar energy is used in lighting. The applied solar power generation system is sent to the storage battery to drive the lamps to work. Generally, the voltage of 12VDC. 24VDC. -6V can get more perfect effect. Therefore, the solar radiation conversion ability of the solar panel is 18VDC for the charging voltage of the 12V storage battery. In order to realize the voltage output of the variable frequency generator is the same as that of the solar battery, so as to achieve the power consumption effect of wind and solar complementarity, the operation process of this embodiment is: select the frequency conversion The outer diameter of the stator chip of the generator is 11Cm, and it goes out of the 12 slots of the outward-facing motor, and the thickness of the stack is 3.0Cm. The diameter of the wire and the number of turns per volt are calculated according to the rated power 300W36V voltage output formula. Layer winding off the line, two-way parallel conn...

Abstract

The invention discloses a permanent magnet frequency conversion power generator which comprises an outer shell, a main shaft, a bearing and coils. The permanent magnet frequency conversion power generator is characterized in that a permanent magnet block is pasted on the inner part of the outer shell; the main shaft is in a hollow structure, and is fixed on the bearing; a plurality of coils are wound on the main shaft; a wire is guided out from the hollow shaft; the outer shell is driven by wind power, water power, fire power and other motive powers to rotate around the main shaft; the coils cut off a magnetic force wire during the rotational process of the permanent magnet and emits current, and the current is output to an electricity using device or a storage electric appliance from the wire at the middle of the main shaft; and a full-magnetic suspending and magnetic push-pull combined device is formed in the shell through the pasted permanent magnet block and an installation panel, so that the permanent magnet frequency conversion power generator can rotate continuously when rotating to a heteropolar interval, the friction resistance in operation is reduced, the driving power consumption is reduced, and rated power output can be emitted out with external micro force driving and low rotation speed, and electricity energy is supplied independently and normally.

Description

technical field [0001] The invention relates to the technical field of generators, more specifically to a variable frequency generator using permanent magnets, which is suitable for thermal wind power or hydropower generation. Background technique [0002] At present, the traditional generators used at home and abroad are dominated by synchronous generators. The synchronous generator has a large energy consumption factor in the internal structure, which affects the coal consumption and carbon dioxide emissions of the thermal power plant. The main reason is that the manufacturing process of this synchronous generator has always strictly followed the rotation of the generator. Part of the rotor and the static non-rotating motor stator, the number of pole pairs of the electromagnetic field formed by the coils must be kept consistent in the machine to achieve synchronous operation. The frequency of the output power is maintained at 50 Hz of the domestic power grid. Or the forei...
