Embedded System for Online Monitoring of Induction Motors

Induction machines play a important role in industry and there is a demand for their reliable and safe operation. Different failures occurs in induction machines gives excessive down times and generate large losses in term, and this motivates the condition monitoring of induction motors. The condition monitoring includes taking measurements on three phase induction motor when it is operating in order to detect faults reducing both unexpected failures and maintenance costs. Condition monitoring of induction motors reduce the cost of maintenance and the risk of unexpected failures. In condition monitoring maintenance, one does not schedule maintenance or machine replacement based on previous records or statistical estimates of machine failure. The system for condition monitoring uses sensors for measurements of different parameter while a machine is in operating condition to determine if a fault exists. The project is to monitor the operating conditions of three-phase Induction motors. This system is based on a low-cost electronic device that can acquire and pre-process current, voltages and temperatures and speed transmit processed key-information related to the motor operation conditions using ZIGBEE wireless technology.
