| Abstract |
Measuring the rotor temperature of an electric machine can not only safeguard the system fromoverheating, but can also improve the control and thermal utilization of the drive. In this contribution anovel on-rotor temperature acquisition system will be introduced, based on low cost circuitry andfeaturing an innovative energy harvesting system which uses power transfer induced by the commonmode voltage alternation in inverter-fed drives. It is shown that using a simple and versatile energyharvesting antenna is sufficient to power the system and that Bluetooth Communication is suitable totransmit the measured data to the receiver, located outside of the machine. |
