Housed in compact packages from 40–80 mm flange sizes, DMV Series can be driven by any servo drive with UVW commutation capabilities. Servo motors are pre-wired with 1 m long cable leads and are equipped with incremental encoder at 2,000 P/R for positional feedback. UL standard compliant, motors feature IP67 protection rating for harsh environments such as falling debris or liquid splash. Optional electrical magnetic brake is available.
CMOS DDR SDRAMs offer densities up to 1 Gb.
