Stepping motor operating status monitoring system based on wireless sensor network

Demagnetization will appear when stepping motor internal operating temperatures exceed about 130deg, and causes decreasing of the output torque and out-of-step. A wireless sensor network was applied to design a new type of stepping motor operating status monitoring system. In order to realize an easy and reliable monitor, the improved algorithm-directed diffusion protocol was introduced into wireless sensor network system. Atmega128L and CC2420 were adapted to design the sensor node. The monitoring system will alarm when surface temperature of stepping motor exceed 90degC, so as to take steps and guarantee the safe of field equipments. The experiment results indicated the monitoring system is effective, and attain the requirement of monitoring.
