Design and Development of Brushless Motor Thrust Stand
Project Area of Specialization RoboticsProject SummaryBrushless motors have replaced brushed motors in almost every field because of their so many advantages. They are being used in all the fields of life, in transportation and traveling, in ventilation, and also in Aero-modelling. During the use of the motor in a certain application, there are certain parameters of the motor to be checked which include power consumed, current flow, the thrust produced and temperature of the motor etc. Brushless motors are used widely in electric aircraft. Selection of the perfect motor to carry a required load or to travel a certain distance is mandatory which includes the study of thrust and time of flight for a motor. And, so the requirement of a thrust stand for brushless motors has only increased with the advancement of technology. Thrust Stands are required to determine firstly the perfect motor and their respective propellers for a certain task and secondly to check the overtime efficiency of the motor to estimate its feasibility for future use. Accurate values determination of these values followed by thrust coefficient estimation plays a significant role in the aviation industry. BLDC motors are used as a clean electric alternative to gasoline engines for fixed wings aircraft as well as in quad and hexacopters. ide industrial application of BLDC motors generates a necessity for a thrust bench that can measure accurate values and generate real-time plots of input vs output parameters of a motor. To design a simple pole thrust stand is our goal for a better choice of motors and their respective ideal parameters for different tasks.
Project Objectives- Data Inquiry
- The efficiency of Electrical Motor
- Efficiency of Propeller
The design and development of a Brushless Motor Thrust Stand are to determine the efficiency of a motor, with and without different propellers, and to study the working parameters of a motor at different speeds. The input parameter is a throttle in the form of PWM and the output parameter is Thrust, of course, other parameters like power, voltage, current, and rpm are also necessary and are as well logged in. The steps in the design and development include coding and circuit formation and integration using Arduino and Proteus where the circuit includes different sensors attached as well, the fabrication of the thrust stand by first developing a CAD Model using CATIA V5 and then practically designing it, circuit and thrust stand integration and designing of a MATLAB GUI to be used for data acquisition and providing real-time plots of parameters for the case study. So that the data stored can be used for analysis and standard reference for future purposes.
Benefits of the ProjectThe thrust stand will provide us:
- A platform to estimate the motor performance with different propellers.
- Log files to estimate motor performance degradation which will prevent us from loosing lots of time every time we are to use BLDC motors.
- Determination of a motor's fitness for service for a task depending on the requirements of the task.
- A Fully operational Thrust stand.
- Brushless motor performance analysis results.
