The Difference

One that affects aircraft performance is the thrust. The thrust is determined according to the requirements of the aircraft itself. This study uses a thrust test stand that uses a mass gauge as a thrust gauge, using two brushless motors and five propellers to determine the optimal thrust for X-UAV Mini Talon aircraft flying missions. The thrust required by the X-UAV Mini Talon aircraft - is known to be 0.6755 N for cruise flights and 4.979 N for take-off aircraft. After testing, the smallest thrust is produced by the configuration of the DYS 2826-13 brushless motor with a 5x3 inch propeller, while the biggest thrust by the RacerStar BR2212 brushless motor with a 10x6 inch propeller. Compared to calculations with propeller static thrust equation, the difference in thrust in testing with propeller static thrust ranges from 15% to 25%. Therefore, the optimal configuration for flying cruising is the DYS 2826-13 brushless motor with a 5x3 inch propeller, which produces a thrust of 0.988 N. Then, for the optimal configuration take-off is the Brushless DYS 2826-13 with a 9x5 inch propeller, which results in a thrust of 6,151. The configuration above was chosen because it is more efficient, with smaller current requirements compared to other configurations with more or less equivalent thrust.

Abstract A brushless motor and propeller test stand is used to test brushless motors and propellers. This testing instrument is still only available in research laboratories. Students and researchers are unable to use laboratory facilities because of the Covid-19 epidemic, thus students must be able to do tests independently from home. Purchasing this testing instrument would be too expensive for students. It is essential to construct a brushless motor and propeller testing instrument at home using simple components that are easy to get on the marketplace. The design concept reads force data using a loadcell sensor and an HX711 driver, and current and voltage data with an INA 219 sensor. The brushless motor’s rotational speed is controlled by a potentiometer. Force, current, voltage, and power are all examples of test results data. A 16×2 LCD is used to show data immediately. Data is also transmitted via a USB connection to a computer device for storage or additional analysis. This study proposes a simple brushless motor and propeller test stand that can measure forces from 0 gf to 1000 gf with an error rate of 0.72 %. The power that can be read ranges from 0 mW to 18960 mW, with a 0.59 % error rate.

Control Implementation

Accurate torque control of a brushless motor requires the motor’s torque characteristics, which can be captured by a periodic function in motor angle. This paper presents a direct adaptive controller for torque control of brushless motors, which estimates the Fourier coefficients of the periodic function based on the measurements of motor phase voltage and angle. It will be analytically shown that the proposed adaptive controller achieves torque tracking regardless of the trajectories of input signals. Moreover, the adaptive controller does not rely on the modeling of the mechanical load, and that makes control implementation simple and modular. Experimental results obtained from the McGill/MIT motor have demonstrated that motor torque converges to the command torque.

Low Efficiency

Abstract Efficient use of resources is a very important consideration for every production process, especially where waste materials are used as raw materials. One example of these kinds of processes is dry ice extrusion. Based on the subject literature, it can be observed that the machines available in the market that are used to compress dry ice are characterized by high working force value. This leads to low efficiency of resource consumption, in regards to both electrical energy and carbon dioxide. This paper presents a proposed design of a test stand used for measuring compression force as a function of piston displacement in the course of the dry ice extrusion. The first part of the article presents the testing methodology and test stand design. The second part presents the results of measurement of compression force as a function of piston displacement with three different die types. The results of the study allowed to establish the difference between the values of the measured limit force and the values calculated with an analytical model. The test stand design and the results presented in this paper are important for further research and development works in the area of efficient extrusion and compaction of dry ice.

Mixture of DC brushed motors and DC three-phase brushless motors has been employed in complicated robotic systems, in order to control different types of motors may using commercial chipsets. Although these commercial chipsets are capable of driving different types of motors, the users are required to define the type of motors they are controlling through software. Defining the type of motors wrongly may damage the motors. Moreover, if a motor is replaced by another type, users would need to modify the software. The paper provides an auto-detection module that can be employed in a servo motor control system with a hybrid commutation control, wherein the hybrid commutation control can drive either a DC brushed motor or a DC brushless motor.
