At last year's show, Elmo showed this annular shaped board that goes into an Israeli missile. It contains four axes of servo controllers with each axis capable of driving 16 kW. The tiny board on the business card is called the Gold Bee and is billed as the most powerful servocontroller of its size, handling 4 kW. It has a sample time of as low as 50 µsec for current, velocity, and position loops.
