Motor Temperature Estimation

The Motor Temperature Estimation function estimates the rotor and stator

temperatures.

Function inputs

The Motor Temperature Estimation uses the following information to calculate the

rotor and stator temperatures:

• Estimated rotor and stator resistan ces

• Thermal properties of the stator and rotor winding materials

• Motor ambient tempera ture

The estimated rotor an d stator temperatures are cal culated using online parameter

estimation. The thermal properties of the winding materials and the motor ambient

temperature are int ernal drive constants.

Function outputs

The following table sp ecifies the outputs of the Motor Temperature Estimation.

Variable Description

Rotor temp Estimated rotor temperature. Degrees C or Degrees F

Stator temp Estimated stator temperature. Degrees C or Degrees F

Power Dip Protection

The Power Dip Protection function sustains DC link voltage when a low voltage

condition is detected.

Function inputs

The following table specifies the input variables of the Power Dip Protection

function.

Variable Description

DC bus feedback DC link voltage. DC volts

Function configuration

The following table specifies the configuration parameters for the Power Dip

Protection function.

Parameter Description

Power dip control Specifies one of three functional modes:

Disabled

Enabled with standard operation

Enabled with custom operation

Custom pwr dip time Length of time that the function attempts to sustain the

DC link in custom mode. Seconds
