The 130J12205EC-17BC offers 28 N.m holding torque from a 205 mm NEMA 52 body, drawing 6.8 A per phase on a 24 mm shaft. It shares the heavy-duty frame with the 35 N.m unit but with a shorter stack, trading a little torque for lower inertia and a shorter envelope.
The 3-phase winding with integrated 17-bit encoder provides smooth torque and high-resolution position feedback. The drive continuously compares the commanded position with the encoder reading and corrects any step error in real time. For heavy-load automation, this removes the risk of silently lost steps during acceleration or load spikes.
Holding torque is rated at standstill. Running torque falls with speed as current build-up in the 6.8 A winding lags the electrical cycle. Closed-loop current management keeps the motor cooler during long dwells, and the 24 mm shaft provides a stiff connection to gearboxes or direct couplings.
Applications include CNC machine tools, packaging machinery, factory automation, precision robotic mechanisms, textile and printing machinery, food processing, and automated handling mechanisms. The 28 N.m rating covers large rotary tables, heavy conveyor indexing, and multi-axis machines where load changes are frequent.
