ACTIVE TEMPERATURE ESTIMATION FOR ELECTRIC MACHINE

Title:

ACTIVE TEMPERATURE ESTIMATION FOR ELECTRIC MACHINE

Document Type and Number:

Japanese Patent JP2003134869

Kind Code:

A

Abstract:

To provide a system which estimates the temperature of an electric machine.

This system includes a step, in which the temperature value corresponding to a temperature signal 23 from a thermosensor 13 connected operationally with a controller is obtained and a step, in which a temperature signal corresponding to a measured temperature is transmitted to the controller. The controller executes a temperature estimating process 100 and is connected operationally with a switching device, which is connected operationally between an electric machine and a power supply and responds to the controller. Further, a storage medium, which is encoded with machine-readable computer program codes for the estimation of the operating temperature of the electric machine, is released. The storage medium includes instructions, by which the controller can realize a method for estimating the operating temperature of the electric machine.
