Title
A Wireless System for inner Temperature Measurement of High Speed Electric Motors
Abstract
The design of an electric motor requires, in addition to electromagnetic modeling, also a specific thermal analysis. The search of the maximum performance with minimum dimensions leads to a rise in internal temperature. Above certain limits, this can lead to loss of performance or even to irreversible damage, such as the demagnetization of the magnets or stator windings deterioration. Therefore, it is important to be able to accurately estimate the temperatures at critical points. This can be done with the help of models and simulation tools. However, modeling may be misleading if it is not supported by experimental evidence. Considering that an error in the estimation of temperatures may have non-reversible consequences, it is very important to validate the models by comparing numerical estimates with data obtained from an experimental campaign. In this case, it is necessary to measure the temperatures in the various internal points of the motor: both in the stator part and in the rotor part.The measurement system introduced in this paper involves the use of 24 type-K thermocouples for temperature measurements up to 250°C with a resolution of 0.25°C and sampling frequency equal to 1Hz. The system consists in two circular-shaped PCB with a diameter of 46.8mm, one placed on the stator and one on the rotor.
