Abstract
An arrangement for determining a temperature of an electric machine includes a supply unit for operating the electric machine, with a first temperature of the electric machine computed with a first thermal model of the electric machine in the supply unit, and a computing facility connected to the supply unit by way of a data transmission channel, with a second temperature of the electric machine computed with a second thermal model of the electric machine in the computing facility. The supply unit and the computing facility communicate by way of the data transmission channel so as to enable the computing facility to determine the second temperature of the electric machine with the second thermal model even when no current is supplied to the supply unit.
Claims21
An arrangement for determining a temperature of an electric machine, the arrangement comprising:
- a supply unit for operating the electric machine, the supply unit comprising a first thermal model of the electric machine stored in the supply unit, with the first thermal model computing a first temperature of the electric machine, and
- a computing facility connected to the supply unit by way of a data transmission channel, the computing facility comprising a second thermal model of the electric machine stored in the computing facility, with the second thermal model computing a second temperature of the electric machine,
- wherein the supply unit and the computing facility communicate by way of the data transmission channel so as to enable the computing facility to determine the second temperature of the electric machine with the second thermal model even when no current is supplied to the supply unit.
A method for determining a temperature of an electric machine, comprising:
- when no current is supplied to a supply unit operating the electric machine, determining the temperature of the electric machine with a thermal model of the electric machine in a computing facility, which is connected for data exchange with the supply unit.
