The iESS86-80-120-17BC is a large-frame integrated stepper motor on an 86 mm base with a 156 mm body length. It combines the motor and its drive in one housing and carries a 17-bit absolute encoder, which makes it a suitable building block for high-load axes that must keep their position reference without a homing run after power-up.
The 17-bit absolute encoder reports the absolute shaft position, so the controller always knows where the axis is. The closed loop corrects position in real time, combining the torque behavior of a stepper with the positioning discipline of a servo. This arrangement reduces the risk of step loss on heavy loads and supports multi-turn position tracking.
With 12 N·m holding torque, the unit is suited to heavy positioning work such as machine tool axes and large indexing tables. The drive is tuned for low heat generation, which helps keep the large frame from transferring excess heat into the machine structure. Low vibration and fast acceleration are supported by the closed-loop response.
The motor is applied in factory automation, packaging machinery, robotics and CNC machine tools where high torque and absolute position feedback are needed.
