The 110J12190EC-17BC is a 3-phase closed-loop stepper in a NEMA 42 frame, rated 6.8 A per phase with 20 N.m holding torque on a 19 mm shaft. The 190 mm body provides the stack needed for heavy rotary table and CNC axis loads.
Closed-loop control here relies on the integrated 17-bit encoder, which reports rotor position to the drive with high resolution. Any mismatch between commanded and measured position is corrected immediately, so the axis does not accumulate error across a cutting or indexing cycle. This is the practical advantage of closed-loop stepping: the motor behaves like a servomechanism for positioning purposes while keeping the simplicity of a stepper system.
Holding torque is measured at standstill with rated current. As speed rises, torque decreases due to winding inductance. The 6.8 A rating sets the thermal limit; closed-loop drive current reduction during idle helps keep the motor within its temperature budget on intermittent duty.
The motor serves CNC machine tools, packaging machinery, factory automation, precision robotic mechanisms, textile and printing machinery, food processing, and automated handling mechanisms. Its 20 N.m rating fits medium CNC axes, rotary indexing tables, and heavy feed mechanisms in production lines.
