Current limiting for stepper motors

current limiter

[Ito-Brazil] pointed out N-Labs simple current limiter for stepper motors. A current limiting system will let you run stepper motors at higher speeds, with greater torque and efficiency without overheating. This particular design is meant to improve upon the common L/R and Chopper drivers. It can handle high voltages without using large resistors and is high performance without using expensive ICs.
