DE202013008855U1 - Micro wind generator for power generation from the wind for electric bikes, electric motorcycles and electric vehicles - Google Patents

Abstract

Micro wind generator according to claim 1, characterized in that it consists of 3 main parts (wings in the protective cage, generator and charge controller) make the whole generator by special design much smaller in size and lighter in weight.

Description

This document describes a permanent magnet AC synchronous generator "Micro Windgenerator" for use on, for example, electric bicycles. The construction described here is made possible by the special construction which makes the system much smaller in size and lighter in weight. This allows efficient and advantageous applications and applications of micro wind generators for power generation, for example, on electric bicycles. About a charge controller, the energy generated is fed directly into the example Fahradakku. Thus, the use and Einaztdauer of the available energy is extended at Elektrofahradakku. Another advantage is that a longer life of the batteries is given by simultaneous charge and discharge.

An important point is that the generator is designed for low speeds up to 800 rpm and does not have to run fast like a very high-speed turbine. This advantage minimizes blade noise during operation. The charge controller will adjust the feed voltage already at 3 meters / second wind speed for a charge start. The driver or user will produce more or less energy while driving, depending on how fast he drives. The dimensions and weight of the system are so small that the user no longer has to use force due to the counter-pressure or the generator during operation. Due to the inclined position of the winding package and the special design of the groove legs and individual sheets, it ensures detent point clearance and thus an optimum sine curve at the generator output. In particular, these systems produce power even at low wind speeds. Despite this non-point construction of the generator, it has very low distances from the magnets to the winding package and can thereby produce more power overall than conventional systems of the same size (weight or dimensions) over all wind speeds.

In the same size, the micro wind turbine is unbeatable. Similar generators operate at very high speeds from 2000 to 4000 rpm. At the appropriate speed of maximum 800 rpm. The micro wind energy system generates electricity and is completely environmentally aware.

The micro wind turbine can be easily dismantled and attached to another electric bicycle if necessary, provided that it also has energy requirements. It can also be taken on the go in your pocket mobile.

The user will be able to use a robust, reliable micro-wind turbine anytime, anywhere and, if needed, quickly turn it on and off. The screw connections are designed in such a way that a theft should not be possible.

The micro wind turbine described here is lighter, more efficient, multi-pole in its performance classes compared to conventional generators and contains no components to be acquired in the market apart from standard ball bearings and standard screws. The components of the system described here are coordinated with each other and work together in the system combination of a wind turbine with the components such as charge controllers in the highest efficiency. The special design allows a construction which makes the wind generators smaller in size and lighter in weight than conventional ones.

Advantages of these micro wind generators:

• 1. Less overall weight and size in the respective performance class
• 2. Higher number of poles in the rotor and winding
• 3. Rastpunktfreiheit
• 4. Quiet operation and less noise emission
• 5. Better production costs due to smaller design
• 6. No commercially available elements except ball bearings and screws
• 7. Lightest design for permanent-magnet rotor with magnets
• 8. Extends the life of the respective battery capacity
• 9. Charges the batteries while driving
• 10. Extends the life of the batteries
• 11. Better design for better cooling
