A method for estimation of torque, shaft speed and energy efficiency has been developed. An embedded system is employed for acquiring electrical signals from the motor and local processing. The calculated values are transmitted to a monitoring unit through an IEEE 802.15.4-based wireless sensor network. At the base unit, various motors can be monitored in real time. To choose the method to be used, a survey on the main methods was made. The method by air-gap torque was considered the most appropriate to the requirements for being accurate and non-invasive. An experimental study was conducted to observe the accuracy of the estimated methods used, and the relationship between the wireless sensor network performance and the spectral occupancy at the operating environment. Therefore, the embedded system was deployed on a workbench of dynamic sinusoidal torque in an i...

Online Efficiency Estimation on Three Phase Induction Motors Using the Air Gap Torque Method

Embedded System for Speed Estimation by Means of Sound Analysis in Three-Phase Induction Motors

Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering, 2018

Electric motors consume a large portion of the electric power generated. Three-phase induction mo... more Electric motors consume a large portion of the electric power generated. Three-phase induction motors are the most used in industries, for their robustness, reliability and easy operation. They are inserted in the most diverse processes as the main electromotive force. Measuring speed directly on the motor shaft is no trivial task, because it requires time and additional cost due to adaptations of speed transducers to the axis, which causes costly stops to the process in which this motor is inserted. For this reason, manufacturers and research centers around the world have been developing speed estimation methods based on sensorless techniques. The speed measurement in motors can be used for various applications from vector control of the machine to failure analysis. In this work, a new method was developed and installed in an embedded system to estimate the speed in threephase induction motors through the FFT motor sound analysis. This technique proved to be reliable, showing good accuracy in comparison to the measured speed on the shaft, demonstrating the effectiveness of the method and applicability in other areas of technical and scientific relevance such as analysis and prevention of bearing failures or any mechanism involving shaft rotation.

Implementation and Deployment of an Intelligent Industrial Wireless System for Induction Motor Monitoring

Journal of Dynamic Systems, Measurement, and Control, 2017

Despite their importance in the productive sector, few motors are properly monitored, mainly due to the high cost of the monitoring equipment and the invasiveness in their installation. This paper presents the implementation and deployment of an industrial wireless sensor network (WSN) to monitor three-phase induction motors. Embedded systems were developed to acquire signals of current and voltage from sensors installed in the motors' terminals, perform local processing to estimate torque and efficiency, and transmit the information through the WSN. The method used to estimate the variables is based on the air-gap torque method. Before the deployment in the industry, experiments were performed to validate the system in laboratory. Finally, the system was employed in a real industrial environment, where different analyses and diagnosis...

On the Impact of Local Processing for Motor Monitoring Systems in Industrial Environments Using Wireless Sensor Networks

Structured cabling and sensor deployment are usually more expensive than the cost of the sensors themselves. Besides the high cost, the wired approach offers little flexibility, making the network deployment and maintenance a complex process. In this context, wireless networks present a number of advantages compared to wired networks as, for example, the ease and speed of deployment and maintenance and the associated low cost. However, WSNs have several limitations, such as the low bandwidth and unreliability, especially in harsh environments (e.g., industrial plants). This paper presents a theoretical study on the performance of WSNs for motor monitoring applications in industrial environments, taking into account WSNs' characteristics (i.e., unreliability and communication and processing latency)...

Regarding the type of motors usually employed, about 90% are three-phase AC induction based [1], mainly due to its cost effectiveness and mechanical robustness [2].

Thermal property measurement using a thermal wave generator

It employs two different materials, so it is a differential instrument. In this proposed method a thermal wave is generated on one of the surfaces of a given sample, and the temperature is measured at the other surface. From the relationship between the input and output waves is possible to obtain the thermal conductivity of one material. The equation of heat conduction, which describes the behavior of the system, on the materials was deduced and simulated, allowing to determine the temperature at any point of the materials. Along with the equations, the Network Simulation Method was applied to solve the problem, but with a different approach. The experimental setup uses thermoecletric coolers to control temperature, and T thermocouples to measure the temperature. The materials used to apply the method were both thermal insulating and conductive, and with few millimeters thick. Several experiments were performed in order to validate the method and they indicate the feasibility of the instrument. α -Thermal diffusivity (m 2 /s) κ -Thermal conductivity (W/(mK)) ρ -Density (kg/m 3 ) C p -Specific heat capacity (J/(kgK)) h -Heat Transfer Coefficient H -Sample thickness (mm) L -Total thickness (mm) β -Material parameter ( iω α ) ω -Angular frequency (rad/s)) κ -thermal conductivity (W/(mK)) R -Both sample and reference radius (mm)
