The advanced Duyunov induction motor is designed on the principle of combining the motor windings according to the Slavyanka scheme, which provide for the inclusion of parallel star and triangle configurations. In fact, the invention is a six-phase engine connected to the network in three phases. Consider the features of this product, its characteristics and customer reviews.
Interesting information
The parameters of the motors are significantly improved by combining the windings, thereby increasing their efficiency. Reducing energy losses allows you to reduce the size of the Duyunov engine, while not losing power. More than two hundred various schemes have already been developed that make it possible to use elements for motors of different sizes, depending on the scope of their application.
The developer D. Duyunov has many years of experience in creating drives for cars, but a new idea is aimed at making the models accessible to the general public. Including scooters and bicycles can be equipped with such a device.
History of creation
Devices whose configuration resembles Duyunov induction motors have been developed before. However, their use on vehicles was very limited. This was due to the lack of the possibility of using electronic DC-to-AC converters.
The basis of the invention is a copper brazed rotor, the design of which includes a pair of closed-type electric rings and rods interconnected by soldering. The weight of the entire fixture is reduced by machining the top on a lathe.
Briefly about the developers
Duyunov Dmitry Alekseevich, together with his son and a group of like-minded people, became the first team of engineers to realize a silent asynchronous motor. Subsequently, a patent was obtained for the invention, and the company AS and PP was established, specializing in the development of improved lighting technologies, plasma and welding innovations.
The inventors called their pride the Duyunov engine in honor of the chief designer. The company also successfully introduces the latest cutting and welding methods for non-combustible materials. The beginning of the development and creation of the motor wheel is considered to be 2015. The main goal of the team is the manufacture of electric motors available to the public, which over time will be able to significantly displace units on internal combustion engines, as well as improve bicycles and scooters.
How does it work?
The Duyunov engine is equipped with a new type of starting winding, which makes it possible to obtain a high starting effect. At the same time, a decrease in operating currents is observed, including on standard power units. Previous attempts to create such a design have failed due to the low starting torque and low specific power of the usual windings. The first introduction of innovative technologies was precisely the rear motor wheel of the bicycle.
The device operates according to a special design and technical scheme. This is due to the combination of standard windings of the "star" and "triangle" type in one block. This configuration became known as the Slavyanka and received completely new electromechanical capabilities.
Scope of application
The rear wheel of the bicycle, equipped with the type of engine under consideration, allows you to increase the working life of the equipment and simplify its operation. In addition, similar analogues can be installed on cars, as well as military and special vehicles. According to the characteristics, this power unit is in many ways superior to the development of Tesla.
Duyunov induction motors are designed for equipment that requires compliance with elevated standards in terms of noise and vibration. These parameters were significantly reduced by reducing the acoustic effect caused by electromagnetic waves. The main winding is located in the compartment, the induction vectors of which form a 30-degree angle.
Testing
The invention in question has been successfully tested on four-wheeled units. The prototype was mounted on the "Zaporozhets". The car at international competitions managed to get around the Korean car "Kia" in terms of speed and mileage. On a single charge of the battery for the motor wheel, the vehicle covered almost 650 kilometers. The objective advantages of this power unit include the ability to equip the machine with all driving autonomous wheels.
The device was actively presented at various competitions and exhibitions. However, it has not yet been launched into mass production. Dmitry Duyunov considers the possibilities of effective implementation of the idea in the domestic market, as well as the economic component of the project.
Features
The invention is distinguished by a common original scheme, which allows you to reach speeds of up to 250 kilometers per hour. The installation is powered by electricity generated by the engine. The main part of the motor is placed in a wheel, weighs 18 kilograms, and produces about 35 horsepower. To get an inertial action, just one click is enough. This makes it possible to maintain uniform movement of the vehicle in the mode of 70-80 km / h.
The motor-wheel for a scooter refers to electrical equipment, its analogues are used in the automotive and light industries. Installation can be carried out in the initial configuration or after additional modernization. Such an engine weighs six times less than a standard 20-kilowatt motor. The first tests of the unit passed in Germany, it is planned to establish production in Russia, as well as patenting in Europe and America.
What is the difference between a motor wheel for a scooter and a car from its Chinese counterparts?
Models similar to the engine under consideration are produced in China. However, the brainchild of Duyunov has a number of undeniable advantages:
- It is resistant to temperature extremes.
- It features a cheap and relatively simple assembly.
- No magnets required.
- The product can be made entirely from domestic elements.
- Speed indicator - 100 km / h.
- Anticorrosion properties are at a high level.
- The manufacturing price is about 30 percent lower than the identical rate of foreign counterparts.
- The device is characterized by minimal parameters of vibration and noise.
- This engine is characterized by durability and high working life.
- Maintenance does not require special expenses.
- The unit has an increased range.
What does Duyunov say about his invention?
According to the engineer, the design in question can fit into the dimensions of a standard automobile wheel. At the same time, the power of each element will be 20 kW with a motor torque of 1000 rpm. The total power will be 80 kW, which exceeds 100 horsepower, and this is quite enough for a city vehicle. The mass of the unit will be only 18 kilograms, which is quite acceptable, given the lack of drive shafts and hubs used in the standard layout of a car.
First of all, the increase in engine power is carried out by increasing the thickness of the outer winding. On average, it is 350 mm at 2.5 kW, and 700 mm is enough to achieve a parameter of 20 kW. Thanks to timely patenting, the invention is protected from plagiarism, although attempts to circumvent this point are scheduled regularly.
Is it possible to make a motor wheel yourself?
To make the motor rear wheel of a bicycle, the purchase of a suitable type of wiring and several fuses will be required. Having a general knowledge of electrical engineering, it is necessary to familiarize yourself with the principle of operation of the unit in question. In fact, the device is an electric DC motor. The power indicator on such models can be adjusted within 2.5-10 kW.
The speed of the electric bike will be at least 60 kilometers per hour. Additional settings for this device are not required. For the correct and durable operation of the unit, it is necessary to carry out the correct and verified calculations of the assembly elements. This approach will make it possible to choose the optimal working conditions, eliminating the subsequent erasure and jamming of the motor. If this moment is taken irresponsibly, there is a high probability of deformation of all parts of the unit. As components, you can use used parts if their technical condition is normal. The remaining elements will have to be purchased at specialized retail outlets.
Tools and equipment
For the independent manufacture of a motor wheel, the following materials will be required:
- New or used wheel with a diameter of 20 to 28 inches.
- Battery.
- Speed switch for adjusting driving modes.
- A special case in which the battery will fit.
- Block with wires and a controller responsible for the motor part of the wheel. As a rule, it is installed in an aluminum case, which avoids atmospheric and other negative influences. The part is a board; often it is placed at the place where the flask is attached to the frame.
If the power of the cycle machine is more than 2.5 kW, care must be taken to ensure minimum gaps in the rubbing elements. For this, special bushings are made on a turning bench. Remember that this power unit is a set of complex electrical circuits. All connections and components require careful insulation, and it is also necessary to consider a system for protecting the electric motor from salt, dirt, sand and moisture.
What do consumers think?
The bike, like the electric car, reviews about the Duyunov engine received mixed. Some users are sure that the motor wheel is the future of the automotive industry. They note that a bicycle or a scooter with such a device does not require rights, and it is also possible to cover considerable distances without significant costs.
Skeptics believe that the Duyunov motor is a kind of fiction, which is no more than another waste of money on an unnecessary invention. Serial production will make it possible to understand how the situation is in reality, and while investors are being searched, we can only wait.
