Wheel-engine with their own hands. How to make a motor-wheel?

A bicycle is an excellent means of transportation not only for those who are constantly looking for adrenaline, conquering new and new mountain and forest roads, but also for those who make short trips for food to the store. Often these people are content with conventional bicycles, the work of which is based on muscular traction. Nevertheless, every year the number of those that move with a small electric motor grows. At the same time, the amateur cyclist is given the opportunity to ride the pedals and thus drive up the steep mountain at an even faster rate. But it is not necessary to purchase a new transport in this case. It is enough only to complete the old special element, which is called the wheel-motor. On what rules need to pay attention to its manufacture, we will consider right now.

How to make a wheel motor with their own hands? Cooking tools

To begin with, we need to purchase a new wheel with a diameter of 20 to 28 inches. You can use the old one, but in this case you need to make sure it works. Ideally, the wheel should not form "eights" on the move and be well adjusted on the spokes.

In addition, to create a self-made motor-wheel you need to buy a battery. And in order to be able to adjust the speed of the moving bike, you need to take care of installing a special speed controller. To store the battery, a case or bag is purchased that corresponds to the dimensions of the battery.

Another important detail is the controller. This element is a block with a lot of wires, responsible for the entire motor-wheel. The controller shows A board located in a metal (most often aluminum) casing to protect against the negative impact of external factors. Most often it is installed in the place of fastening the flask, directly on the frame.

To ensure the continuity of the work of all electromechanisms, it is necessary to prepare a set of fuses and wires. The latter can be used from conventional audio speakers.

Principle of operation of the device

Before you start to make a wheel-motor, you need to understand its principle of operation. This element is a brushless DC motor. The wheel-motor is clipped into the bicycle rim and can be mounted both from behind and from the front (some install it directly on two wheels). By its power, the electric motors used for such bikes can be 250W, 500 and even 1000W. The latter can reach speeds of up to 60 kilometers per hour. True, it is unlikely that it will be safe on a mountain road or in a residential area within the city. By the way, regardless of the power of these motors do not need additional settings, adjustments and maintenance.

How to make a motor wheel with your own hands? Production rules

1. Pay attention to the correct and competent calculation of the nodes. Under such conditions, the wheel-motor can be secured against various pastes and jams. If this is not done, you run the risk of collision with parts, which can cause a breakdown of the entire electric bike.
2. If the details of the sizes and characteristics are suitable for those already in use, do not be afraid to use them in the work. The main thing is that they are in good order. Certain elements, of course, can not be produced independently for a number of reasons. However, this can significantly affect your spending budget. For example, the installation of spokes on the disk will cost about one and a half to two thousand rubles.
   
3. Since the motor-wheel is a combination of the most complicated electrical mechanisms, it is necessary to take care of the quality insulation of the wires connecting all these parts. It is also necessary to remember that the bicycle (even if it will be used purely for shopping trips to the store) should be well protected against the influence of factors such as sand, road dust, salt, dirt and other harmful elements for the electric motor.
4. If the power of your bike will be more than 250 W, you should think about minimizing the gaps of rubbing mechanisms. Perhaps in this you will need to use special tools.
5. For the manufacture of parts such as bushing and shaft, you need to learn how to work on a lathe. It is unreasonable for one electric wheel to acquire it. Therefore, in this case, either we order it for rent, or we hire a familiar turner. The latter option, as practice shows, is faster and safer.

Advantages of using a motor-wheel on bicycles

Firstly, thanks to the electric motor, you can overcome great distances without any physical effort, which is especially important for the elderly and unprepared people. Secondly, for driving on such transport, unlike motorcycles and scooters, no rights of a certain category are required. And this means that absolutely everyone can manage it. Thirdly, due to the compactness of the bicycle, you will not stand in constant traffic jams. In addition, there is no need to purchase a separate garage to store such vehicles.

Service

The made motor-wheel with own hands (or rather its electric motor), unlike the internal combustion engine, almost never needs additional maintenance. And this means that the cost of its maintenance will be minimal.

The Shkondin wheel-motor operates on battery power, which can be overcome up to 30 kilometers without a charge. But even if the battery is discharged, you still do not have to tow it - at any time this transport can turn into a normal bicycle, the movement of which is carried out by muscular effort.

How much does this item cost in stores?

On average, a new electric motor, mounted on the rim of the bicycle, can be purchased at a price of 10 to 30 thousand rubles (the motor-wheel for the car is even more expensive). It should be noted that the cost can vary significantly from the capacity of the device. A set of motor-wheel for a bicycle can cost 3 thousand, but it will last only 200 meters. By making it yourself, you can choose for yourself such a device that would meet your requirements and specifications.
