In-field operation monitoring of induction motors using wireless modules running on harvested power

Modern industries require high efficiency and availability motor driver systems. Proper and cost-effective motor maintenance require carefully programed repair and replacing strategies. Motor operation monitoring can add a valuable contribute to the implementation of successful cost-effective maintenance services. Monitoring systems are nevertheless expensive and require maintenance resources for themselves. Flexible, low cost, easy to install and low maintenance monitoring tools can provide a valuable impact on motor maintenance systems. The recent studies on wireless sensor networks prove that they can constitute one such system thus allowing low cost monitoring strategies.Wireless sensor networks whoever are not maintenance free and present a strong dependence off battery resources. Battery changing is in fact the main obstacle to wireless sensor networks widespread use.
