Determining the voltage constant of a motor experimentally

If the voltage constant ke is not specified in the motor data sheet, you can determine it experimentally.

The voltage constant ke is only required if you are not using an encoder but want to use one of the following functions:

  • Load angle detection
  • Step loss detection

The procedure is described in section "Induced countervoltage".
