Stator thermal model for short-time thermal transients

2014 International Conference on Electrical Machines (ICEM), 2014
This paper presents a thermal model for the simulation of the stator winding temperature in short-time thermal transient. A practical application of the model is the overload thermal limit prediction in electrical drives. The proposed thermal model and its evolution is presented in detail in the paper; the thermal parameters computation, based on a ...

Thermal conductance and its relation to thermal time constants

Journal of Thermal Biology, 1981
Abstract A large body of thermoregulation studies exists in which the proper relationship between the physiological variable, thermal conductance, and heating or cooling time is not recognized. This is owing, in part, to conflicting definitions of conductance which either fail to relate to mean heat flow through the body surface or which fail to ...

Space-Time Dependencies and Thermal Perception

2016
This experiment was focused on determining whether the spatial representation of thermal stimuli is influenced by the temporal parameters of stimulation as has been demonstrated for tactile stimuli. Four warm thermal pulses within the innocuous range of temperatures were presented on the forearm in varying spatial and temporal sequences.

Thermal time response of microfilaments

2000 IEEE/LEOS International Conference on Optical MEMS (Cat. No.00EX399), 2002
The thermal time response of polysilicon microfilaments has been characterized at high and room temperatures. We have found cool down time constants that are several times lower at room temperature than for equivalent filaments at high temperatures. It is proposed that the cool down transient can be directly controlled by "substrate quenching," where ...

Thermal-blooming time constant

Journal of the Optical Society of America, 1982
Thermal blooming is analyzed by using a wave-propagation code to determine the speed of response of the blooming effect to changes in the transmitted laser beam. Results are developed to indicate where along the propagation path the dominant part of the thermal-blooming effects arise.

Stator thermal time constant

49th IEEE/IAS Industrial & Commercial Power Systems Technical Conference, 2013
The thermal model providing motor overload protection is derived from the first order differential equation for heat rise due to current in a conductor. Only the stator thermal time constant and the service factor are the required settings. The thermal model utilizes the full thermal capacity of the motor and allows current swings and cyclic overloads ...

Thermal converter time constant and response time

Electrical Engineering, 1958
THE DYNAMIC CHARACTERISTICS of a thermal converter∗ for measuring alternating current or voltage are of some importance in a number of applications. Of these, the time constant and response time are the characteristics most often required. The change of emf of a thermal converter after a step change in heater current is only approximately exponential ...
