Rated speeds range from 2800 RPM to 5200 RPM, and voltage ratings up to 325 VDC for offline drives can be achieved.
All versions are designed with medium to high Ke to accommodate low buss voltage applications; feature rugged IP65 construction; incorporate heavy-duty 0.5-inch shafts and front shaft seals; and are CE, UL and cUL approved.
Motors can be equipped with optical encoders, external holding brakes, Hall effect sensors, precision servo gearing, mating power and feedback cables (packaged in kits), and other customization options to satisfy particular application requirements.
