The design of the cassava slicer machine has a capacity of 38 kg / hour, this machine is designed to design a cassava slicing machine that has high usability, achieving the required motor power so that the desired engine capacity can be achieved, able to determine the exact method of slicing cassava . The working principle of Cassava Slicing Machine is to work when the electric motor is turned on, then the motor will rotate then the motor rotation is transmitted to the pulley, moving the slicing knife by 0.03653 N / mm2. After the shaft rotates, the disc where the blade will rotate and the cassava is ready for slices and the results of the cassava slices will come out through the output funnel. Cassava slicing machine using 1/2 HP motor with 1400 rpm rotation as its driver, and Framework with L St.37 profile material, type A belt, bearing with UCP205-16 type

Рассмотрен вопрос о необходимости повышения качества потребляемой электроэнергии на нефтяных месторождениях. Отмечен один из наиболее эффективных методов повышения качества электроэнергии - активный выпрямитель напряжения. Представлена модель активного выпрямителя, и описан принцип ее работы. Исследована работа макета активного выпрямителя, нагруженного на частотный преобразователь. Приведены осциллограммы токов и напряжений при нагрузке выпрямителя на преобразователь частоты, а также приведены характеристики макета. Показано влияние искаженной и несимметричной питающей сети на параметры потребляемого тока выпрямителя. Предложены методы компенсации влияния искажений сети на качество работы активного выпрямителя. Представлены сравнительные характеристики выпрямителя при работе с компенсатором искажений.

Dem steigenden mechatronischen Integrationsgrad im elektrischen Antriebsstrang des Automobils wird mit neuartigen Kontaktsystemen begegnet. Unter Einsatz analytischer und numerischer Modellbildung sowie experimenteller Prüftechnik werden Leistungskontakte entwickelt, um hohe Energiedichten innerhalb der physikalischen Komponenten Traktionsmaschine, Leistungselektronik und Batteriespeicher zu übertragen.   The increasing level of mechatronic integration in the electric powertrain of automotive vehicles is overcome by innovative power connectors. Utilizing analytical, numerical and experimental procedures, high-current connectors are developed to transmit electrical loads within the key components electric motor, power electronics and battery system.

Thermal testing of unfixed flatbed dryers was carried out on natural convection heat transfer. Its specifications are 4 number of bed level, using 1/4 Hp and 1400 rpm electric motor power and rotation, 1:60 gearbox ratio, A type of V belt with a length of 686 mm, pulleys diameter of 95 mm, and the shaft diameter of 12 mm in made sB = 70.2 kg / mm2 of the materials. Tests were carried out to determine the thermal performance of the dryer such as the amount of input energy, the energy used to evaporate the water contained in the grain, and its distribution for each level of the bed. The test results revealed that with the input energy of 6.396 kW, it took 125 minutes to evaporate the water in the rice, and the highest thermal efficiency on the 2nd level from the bottom.
