Frameless stator-rotor kit with hollow shaft; customer supplies bearings, housing, feedback, drive electronics and the thermal path; electrical values below are for the star-serial interconnection
Motion & Actuation · Low-voltage frameless hollow-shaft servo motor kit
ILM-E85x13
This record freezes the 85 mm diameter, 13-class stack size of the ILM-E series in the star-serial interconnection published in the official data sheet. Rated torque carries the manufacturer condition that thermal behavior depends strongly on the installation situation, and peak torque carries its 20%-deviation-from-linearity definition.

Known limits
What this record does not prove.
- Electrical values are interconnection-specific; delta-serial and star-parallel variants of the same size have different current, torque-constant and resistance values.
- Rated torque has no published reference mounting or heatsink condition; the installation determines the real thermal envelope.
- The frameless kit is not a finished actuator; no RCI physical assembly, torque, thermal or life test exists.
