# Motor Graph

The Super Servo Plus exhibits some behavior you might be unfamiliar with. It's controller is current limited to protect the servo bus, and keep currents over the PWM cables reasonable.

The natural stall current of the motor used in the Super Servo Plus is \~4.7A, while it is capped to \~3.9A of servo bus draw.

{% hint style="info" %}
To get the most out of your Super Servo Plus while having maintaining an efficient robot servo bus, aim to gear so it operates in the third quadrant of the motor graph (i.e. 450RPM-700RPM).\
\
You'll get better efficiency, while still getting max power out of your Super Servo. Your battery will thank you.
{% endhint %}

{% hint style="info" %}
To gauge where on the below graph your super servo is operating in your design, there are two possible ways.

* Use an encoder and measure rotation speed (make sure to account for any ratio's you might have between the Super Servo and your mechanism).
* Place a PWM extension cable between your Super Servo and your robot wiring. Cut the positive 6V wire, and reconnect them via a multimeter in current measurement mode. Then simply compare the measured current to the current on the below graph.<br>
