Just the thing to guide a guided missile
Not all servo drives come on rectangular circuit boards. The annular shaped board by Elmo Motion Control Ltd. goes into an Israeli missile. It contains four axes of servo controllers with each axis capable of driving 16 kW. The resistor arrays visible on the board are each able to hold 2 kW and work in a regenerative circuit. The whole board can handle up to 14 g rms of vibration. 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.
