Synchronous regenerative drive:
Going one step farther than just regenerative braking, a Sabertooth motor driver will return
power to the battery any time a deceleration or motor reversal is commanded. This can lead to
dramatic improvements in run time for systems that stop or reverse often, like a placement robot
or a vehicle driving on hilly terrain. This drive scheme also saves power by returning the
inductive energy stored in the motor windings to the battery each switching cycle, instead of
burning it as heat in the motor windings. This makes part-throttle operation very efficient.
