If an encoder has a small enough profile, it can fit in many electric motor control applications. That is the goal of the ECI 119 absolute, inductive rotary encoder from HEIDENHAIN. This encoder has low profile (height of 19 mm, outside diameter 92 mm) and large through shaft (50, 38, or 30 mm), while offering 524288 (19 bit) positions per revolution and ±90” system accuracy.
The unit’s bearingless design avoids problems from bearing wear or loading. In addition, concerns of mechanical self heating of the encoder and shaft currents are eliminated. Designs that stay within encoder’s mounting tolerances require virtually no maintenance outside of contamination protection.
