Heidenhain Ring encoder for direct-drive torque motors
The ECI/EBI 4000, an inductive 90-mm hollow-shaft rotary encoder series, was designed 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 6,000 rpm and a maximum vibration load up to 400 m/s2 for scanning unit and 600 m/s2 for rotor according to EN 60068-2-6. The product uses a circumference scanning method and has a position resolution of 20 bits. The inductive circumference scanning makes it possible to compensate position errors common to modular encoders when the center of rotation of the drive shaft shifts.
