DC-injection lets motors do the braking

Much is made of increasingly dynamic performance available from electric motors (and drives), and rightly so. The other side of the equation is ability to stop all that speed and acceleration efficiently, when needed. External braking is the more familiar stopping method, but three-phase ac induction motors provide internal electronic means to slow and brake their motion—among them, dc-in...
