The 86J1880EC-1000-LS-SCG is a 4.5 N·m closed loop Stepper Motor in a NEMA34 frame, pairing a shorter 80 mm body with an integrated holding brake. Holding torque is rated at 4.5 N·m with a 6.0 A phase current and a 14 mm output shaft. The shorter stack keeps the same frame cross-section while reducing rotor inertia, which is useful when the axis must accelerate and decelerate quickly.
An integrated 1,000 P/R encoder feeds rotor position back to the drive. The closed loop corrects step loss in real time, so the motor maintains synchronized motion even when friction or cutting load changes. This also allows the axis to run with a smaller current margin than an equivalent open-loop design, lowering motor temperature during long cycles.
The integrated brake holds the shaft when power is removed. For vertical or inclined axes on packaging and handling equipment this removes the risk of back-driving during a stop or an emergency stop. Brake supply is wired separately from the phase supply so the two can be sequenced correctly in the machine logic.
The motor is specified for CNC machine tools, packaging machinery, factory automation, precision robotic mechanisms, textile machinery, printing machinery, food processing, and automated handling mechanisms. The 80 mm body is a practical choice for retrofits where the original motor cavity is limited in length but the frame size must stay at NEMA34.
Mounting uses the standard NEMA34 flange pattern. Keep ambient airflow clear of the end cap so the closed loop controller and brake can dissipate heat. When pairing with a Lyenwsin closed loop drive, set the encoder resolution and brake sequence in the drive parameters before commissioning the axis. As a distributor, we also provide wiring diagrams and application support to help your team get the axis running quickly.
