Similarities Of Forward Contracts

Električno

The figure below is an example of processed tire, designed for shorter distances, so the lightest possible battery just 1.44 kg range is about 12 km, but the charging time two and a half hours.

Electric two-wheel vehicles are not only ecologically and economically, but a remarkable tool for people who have any disorder or difficulty in moving or walking. In particular, elderly people shortly after the problems renounce the use of bicycles mainly due to problems of overcoming the hump when your feet do not "stand up" more, or it may happen that a sudden fatigue or respiratory problems. If you have any type of bicycle, it can be processed with little skill in the electric bicycle and this will help you make such a contribution. With such processing will still use the wheel, you're accustomed to.

In this paper, which will change in Slovenian I will describe how to modify a simple bike to electricity. Maybe for some pretty basic school, but it is my intention to could anyone with a little manual dexterity, this recovery may take alone.

Ingredients:

1.Brezkrtačni engine suitable for installation in front wheel

Brushless or BLDC motor has a permanent magnet rotor, stator, the electronically controlled magnetic field. Because they have no commutators are stronger and have better efficiency, but require more sophisticated electronic control equipment controllers.

Motor (recommended without Hall sensors "Hallsenzorless") We get to know him, has only three wires for power supply yellow, green and blue. Engines with hallsenzorjem have five thin Zick for sensors that are in the engine.

2.Kontroler, it's electronics, which converts DC battery power into three phase motor.

controller that we used has only 8 wires

Three (thicker), yellow, green, blue, which bind via a connector on the engine.

Three thinner going gas nozzle is a black red and green again through the connector (in my case because of the simplicity of using only one 9-pin connector).

Two thick: red and black on the plus to minus batteries.

If your controller will have more wires, the other is easily removed, because we need to act above mentioned. The controller must be "Hallsenzorless), whereas the engine of this kind.

3.Ročica to control speed.

handle gas has three wires black, red and blue, related via the connector on the controller (black on black, red to red and blue to green

4.Baterijo to the Lithium Iron (LiFePo4) or at least the lithium ion. Lead is not recommended because of the weight , environmental risks and the particular half of the smaller facilities than any Lithium.

The picture of different types of batteries. We are using LiFePo4 24 V 9 Ah in "litlle Frog" housing, sufficient for approximately 22 km of driving without pedaliranja.

Unfortunately, all this still does not get to us. Maybe sometimes the fleas. Batteries We have already seen In some shops, but are quite expensive. Is it that today, thanks Intrenetu, all purchased in China. We recommend PayPal payment

That we have very good experience because there is ordered to Slovenia in a few weeks by express mail n.pr DHL. Fare is quite high for a single set (approximately 70% of the price of goods). The most economical is to buy about 6 sets (in this case the price transport approximately 30% of the price of goods) should be counted in the duty, which is about 5% and 20% VAT, which is calculated on complete price (supply, transport and customs) Approximate price, everything included, were in this case for 6 kits (group purchasing)

Motor € 100 handle gas € 6 € 20 Battery Controller "Little Frog" LiFePO4 charger with integrated 24 V 9 Ah 216 Wh for approximately 21.5 kilometers € 170

cheaper alternative version of the Li ion battery battery in the "Little Frog" housing, included charger,

24 V 5 Ah 120 Wh for approximately 12 kilometers € 130 This version is suitable for those who use the bicycle for short distances.

cables to connect and connectors are available locally, as well as dual-layer ring (recommended) and spokes. Engine installation in the ring is possible in any bike station where you can buy a ring and napere.To will cost you about: dual-layer ring spokes 36 € 16 € 11 pieces and the work is incorporated into the service from 15 to 30 € Konektor9 full n.pr . Molex male and female, € 4 or any other, possibly two, three full, one of which must be one of at least 15 A

So much for the introduction. Let's see how you can assemble electric bike from purchased components:

Battery "litlle Frog" has two parts. Battery, as such, which can always remove n.pr filling or exchanged for backup if you have two.

cap is mounted beneath the seat or the wheel, where we sit very low in the rear trunk.

At the base is the appropriate place for the installation of the controller.

When inserted into the base controller tie the black wire to the minus battery red to red and two are already up in the foot by failing to go past a red switch, which is associated with the key for contact, etc. As with the car.

At this stage it is advisable to base the battery attached to the pipe under the seat, wheels, whereas screws available.

If we are all properly tied, followed by test it. Motor must rotate in the right direction if rotated in the opposite direction only replace two wire for power transmission to the engine, this may happen in some controllers I recommend this test it before finally inserting contacts into the plastic of the connector to be sure that the engine spinning in the right direction.

It remains only to change a front wheel that is fitted with an engine mounted lever for the gas to the rudder, the battery is inserted at the base, both cable routed to the controller, with a key switch on the battery and move with the help of electricity.

links above description was only one možnih.Za reliable service is important as fewer connectors as most errors due to poor contact. In our case, we used only two. One to connect the controller to the controls and the other, which is an integral part of the engine, you can easily replace the tire.
