Template:DCMotor MotorInductance

The inductance of a motor is a critical parameter that can significantly improve motor control when understood. The latest generation of Phidget motor controllers automatically measure the inductance of your motor.

You will hear an ascending pair of beeps after the controller has booted indicating the measurement was successful. You will hear no beep, or a descending pair of beeps if the measurement fails.

Other Considerations

• To properly characterize the inductance of your motor, it must be stopped, or turning very slowly when the controller is opened by your application. If this is not possible for your application, consider manually setting the Motor Inductance in the Attach Event. You can use a previously measured value, or a value from your motor's datasheet.
• Inductance measurements will have variations from measurement to measurement, which may cause slight variability in your motor's behavior. If you would like to limit this variability (or you would like to avoid the audible beeps), you can manually set the Motor Inductance in the Attach Event. You can use a previously measured value, or a value from your motor’s datasheet.
• The API for your controller will specify a minimum and maximum Motor Inductance. If your motor falls outside this range, please contact us for more information.
