A method and system for estimating a parameter of an electric machine, including
a controller and a switching device, the controller responsive to at least one
of: a current sensor, and a temperature sensor. Where the controller executes a
parameter estimation process, which is responsive to at least one of: a current
value, a torque command and the resultant of the parameter estimation process representing
an estimated parameter of the electric machine. The parameter estimation includes
a method for estimating a temperature of the electric machine comprising: a temperature
sensor operatively connected to and transmitting a temperature signal corresponding
to a measured temperature to a controller, which executes a temperature estimation
process responsive to a temperature signal from a temperature sensor.
