Duyunov’s motor-wheel is an asynchronous type motor, which contains a rotor and stator part, it functions from the influence of electric current. The voltage is launched along the rims, and when the phases are switched, it rotates the field and the magnetic induction vector. In an asynchronous unit, the rotation of the rotor is slowed down, the retracted effect is created not by means of an electromagnet, but by means of branches on a short circuit. The synchronous analogue operates at the same frequency with the magnetic current vector from the stator.
General information
A device of the Duyunov motor-wheel type was known earlier. Its scope was limited mainly to light and heavy industry. In transport, this design was not used due to the lack of power electronic elements that allow converting direct current into a variable value.
For the motor invention under consideration, a brazed copper rotor is used, consisting of rods and a pair of trailing electric rings. They are connected by soldering. The upper part of the rotary device is processed on a lathe, which allows to reduce the weight of the entire element.
Operating principle
Repeated attempts have been made to create an asynchronous wheel motor. All of them failed due to the low starting torque and low power density of standard windings. Duyunov motor-wheel received a new type of starting winding, which allows to obtain a high starting effect with a decrease in the supplied currents even on standard power units. As a result, innovative technologies have been tried on a motor wheel.
The principle of operation of the unit is quite specific in a constructive and technical terms. In various areas, there are two types of windings: the configuration of a triangle or a star. The developers of the new induction motor decided to combine both systems into one node. The new modification was called "Slav", it received updated parameters that are not inherent in traditional electromagnetic analogues.
About the developer
The Duyunov motor wheel is named after its inventor, Dmitry Duyunov. Together with his son and a team of engineers, he became the first scientist to create a silent asynchronous power unit. After obtaining a patent for the invention, the designer formed the AS and PP enterprise, specializing in various developments in the field of welding and plasma technologies, as well as energy conservation methods and improvement of lighting equipment.
The company’s team is successfully introducing methods for welding and cutting non-combustible materials that fully replace traditional welding. With the Duyunov team, he began to create a motor wheel in early 2015. The main goal is the manufacture of electric motors for cars and bicycles, accessible to the general public. According to the scientist, the development will allow crowding out cars and motorbikes with internal combustion engines, increasing users moving on advanced bikes.
Destination
The ready-made Duyunov motor-wheel kit is used to equip bicycles, cars, heavy and military equipment. Power plants of this type are durable and affordable in production. The innovative invention has been successfully tested on four-wheeled vehicles. The design of the engine in question in many ways surpasses the similar developments of the well-known Tesla company.
A prototype motor wheel was installed on a ZAZ car. Zaporozhets positively established itself in international competitions, having managed to surpass the Kia brand in terms of speed and mileage. One charge was enough to overcome 640 kilometers of track. Another advantage of this motor is the provision of the car with four independent driving wheels.
Features
Duyunov presented the motor-wheel of a bicycle at various exhibitions and competitions. Judging by the responses of experts, the model expects huge success. However, while the inventor does not dare to launch the project into mass production. The standard reason is the economic cost of the issue and the effectiveness of implementing the idea in the domestic market.
The motor wheel is equivalent to electrical equipment, can be used in light industry, installed on various types of cars. It is mounted in the initial configuration or additionally adapted after small alterations of the vehicle.
The Duyunov asynchronous motor-wheel is usually designed for objects that require compliance with increased requirements in terms of vibration and noise. As a result, indicators of the technical plan of the engine in question make it possible to reduce the acoustic impact and vibration caused by electromagnetic waves. The triangle system and the stars are located in a block whose induction vectors form an angle of 30 degrees.
Test
What is the difference between the invention that Duyunov invented? The motor wheel, the circuit of which is given above, is capable of speeds up to 250 km / h. The unit operates from electricity generated by the motor. The power plant itself is located in the wheel. Engine power with a weight of 18 kilograms is about 35 horsepower. For inertial revolutions of an element, one click is enough. This is the main difference between the model and its Chinese counterparts, which stop after removing the foot from the gas pedal. This feature allows the vehicle to move evenly in the automobile stream at a speed of 70-80 km / h.
Conventional 20-kilowatt engines weigh about a centner. Duyunov's motor-wheel has this indicator almost 6 times lower. The invention is being tested in Germany. The unit can be fully assembled in Russia. In addition, patent pending is planned in Europe and America.
Benefits
Compared to Chinese counterparts, Duyunov’s motor-wheel has several advantages, namely:
- Resistance to temperature differences.
- Simple and cheap assembly.
- Lack of magnets.
- Resistance to pollution and corrosion.
- Duyunov’s motor-wheel, made with his own hands, has a complete import substitution for component parts.
- The maximum speed on the wheel is 100 km / h.
- Cost of production reduced by 30 percent compared to foreign counterparts.
- The equipment has a low noise level and low weight.
- The model is durable and has a long service life.
- Maintenance does not require high costs.
- The modification has an increased range.
DIY Wheel Motor Duyunov
First you need to prepare tools and materials. Among them:
- A new wheel with a diameter of 20-28 inches.
- Accumulator battery.
- Speed controller for adjusting vehicle motion parameters.
- Cover for storage of AB.
- The controller, consisting of a unit with wires, responsible for the overall operation of the motor wheel.
The controller is usually mounted in an aluminum casing to prevent negative environmental influences. The item is supplied in the form of a board, placed on the frame, often in the flask compartment.
Manufacturing rules
To ensure the correct operation of the Duyunov motor wheel made by yourself, it is necessary to provide for the purchase of a set of fuses and suitable wiring. Before manufacturing the device, it is advisable to study the principle of its operation. In fact, the device in question is an electric DC motor. The motor wheel is placed on the spokes of the rim front or rear. The power of such units can vary from 250 to 1000 watts.
A sample per kilowatt is capable of speeds up to 60 km / h. You should not conduct such experiments on mountain roads and winding streets in the city. Regardless of power, the device does not need additional settings and special maintenance.
Duyunov was able to create a motor wheel with his own hands thanks to conducting correct and competent calculations of assembly units. This will allow you to choose the optimal working conditions, as well as prevent subsequent mashing of the unit and its jamming. Ignoring this stage leads to the breakdown of the entire bicycle, up to the complete deformation of parts. Alternatively, it is possible to use used components in the design if they are in a normal technical condition. Items that cannot be made on their own can be purchased at specialized stores.
Total
To make Duyunov a motor wheel with his own hands was not so long ago. It is worth remembering that this is a set of complex electrical devices. All connections and parts require careful and reliable insulation. In addition, you need to worry about protecting the vehicle from sand, dirt, salt and other factors that adversely affect the operation of the electric motor.
With a bike power above 250 watts, it is necessary to ensure minimal gaps in the moving parts. Special bushings are made on a lathe in size. It should be noted several main advantages of using a motor wheel on a bicycle, which users are talking about. Firstly, this vehicle does not require a license. Secondly, an electric motor allows you to travel considerable distances without significant physical effort.
