III.1 / theoretical bases
1. Bicycle dynamo:
The dynamo has two part coils and magnets.
When the bicycle wheel rotates, it will make dynamo shaft rotation, made through the coil magnetic flux variation >>> >>> variability created induced electromotive power.
2. Rectifier Bridge: Effect: adjust alternating current into direct current 3. Capacitors: Effect: the wavy flattened, steady electric current. 4. Pin milium: III.2 / RESEARCH-BASED theory Using bicycle dynamo available contact dynamo spinning wheel to generate alternating current. AC current through the bridge circuit creates a stable direct current load the battery or batteries. Calculating actual data: - Dinamo generate electricity with a voltage from 5V - 6V for rotational speed is unstable. - Through inflow circuit from 5V - 6V to 5V Output current stability . - The intensity of the load line small, less than 1 A. III.3 / STUDY ON THE MODEL OF loaded automatically Dinamo CYCLING - Rectifier simple: _Mo improved form after being compact. _Mo loader image Design: III.4 / PRINCIPLE OF OPERATION In part Dinamo 2 coil and magnet. When the bicycle wheel spin, it will be for Dinamo axis rotation, magnetic field coils through variation >>> >>> varying magnetic flux induced electromotive power generated. AC via bridge rectifier transformer AC DC bar. Convergence refers to the undulating leveled, stable output current for battery charging. III.5 / DIRECTION OF USE CURRENT OBTAINED FROM CYCLING Dinamo 1. Charging the battery backup Because dynamo line drawn from 5V voltage stabilization should match the input voltage of the batteries. Use extra batteries to light bulbs (lamp voltage is 5V) or use the battery charger phone. 2. Using a generator directly into bike lights when motion rectifier bridge When using the line through more stable light up the lamp life will increase. IV / EXPERIMENTAL, RESULTS. 1. The experiments of steady currents derived from the motion of a bicycle dynamo. Experiment 1: Conducting experiments layout includes: - Installation dynamo with rectifier, then connected in series with the lamp 5V, serial with ammeter. - Using a hand drill, drill battery to rotate the AC dynamo to generate results: - Observing the light stable - Measure 0.1 A steady flow Experiment 2: Conduct layout experiments include: - Fitting dynamo with rectifier, then connected in series with the lamp 5V, serial with ammeter. - Attach up to turn the knob bicycle dynamo to generate alternating Results: - Seeing lights Light stable - Measure 1A steady stream 2. Experiments on charge time for the battery backup. Experiment 1: (Use bike) Conducting experiments layout includes: - Installation dynamo with rectifier, and then caught in a spare battery. - Mounting on bicycle knob cranked dynamo to generate alternating current. Cycling from home to school and from school (about .... Km, the average lost ...... hour). Result: The 6000mAh battery is fully charged, it is about time Experiment 2: (Used motorcycles) Conduct layout experiments include: - Fitting dynamo with rectifier, and then getting into the backup battery. - Mounting on the motor (50) to turn the knob AC dynamo to generate electricity. Used car from home to school and from school (about .... Km, the average lost ...... hour). Result: The 6000mAh battery is fully charged, the approximately hour V / ANALYSIS OF RESULTS AND DISCUSSION ▪ Discuss Tools: Features: - Create stable DC 1A, 5V voltage. - Used as a direct light source lighting, or charging for spare battery. - Provide additional energy source serving for everyday activities. ▪ Discuss the design model: Model loader from bicycle dynamo line functions as research purposes. With specific illustration of the model, hoping the model will be implemented in practice in the shortest time. ▪ Limitations of the study: - Model but has been modified but still primitive. - Need Research and improves the protective circuit box, container dynamo ... ▪ User development themes: Continuing research, innovation and design tool generator (as dynamo) but larger capacity . CHAPTER 3: CONCLUSIONS With the design idea "charger automatically Dinamo BICYCLE AND USE CURRENT PLANS USEFUL" simple, easy to use, cheap. This is a practical charger for all the family. Thanks to this loader we can provide more energy everyday activities, reduce electricity costs. With this in mind certainly flawed, hope your teachers and the comments to the group may completed his ideas. Sincere thanks!
