YKA2304ME is identical-angle constant-torque microstep drive with working voltage DC12~40V. It’s designed for various models of two phase 6/8 wire 42~57mm (NEMA 17~23) hybrid stepper motors which current are below 3A.
With the uses of the first advanced six-wire technology, the motor will proceed Automatic Gain Control at high speed and reducing reverse EMF, thus greatly improve the torque output (double torque compared with four-wire drive) in high speed.
