Ring Encoder Outfits A Direct-Drive Torque Motors

The ECI/EBI 4000 inductive 90 mm hollow-shaft rotary encoder series is designed for as a motor feedback system to be used specifically with direct drive torque motors. Features include an operating temperature range up to +115°C, a maximum speed up to 6000 rpm, and a maximum vibration load up to 400 m/sfor scanning unit and 600 m/s2 for rotor according to EN 60068-2-6, impressively demonstrate this. Scanning is performed through a circumference scanning method. With a position resolution of 20 bits, this scanning principle has an extremely positive effect on the mounting and operating tolerances of the application allowing an axial offset of the scale drum to the scanning unit in a range of ±1.5 mm with a maximum drive shaft runout tolerance of 0.2 mm.
