Microstepping provides improved resolution without limiting step rates, and provides much smoother low-speed motor operation. An automated, innovative packaging technology combined with power NMOS FETs and monolithic CMOS logic/control circuitry advances power multi-chip modules (PMCMs™) toward the complete integration of motion control.
