86J1895EC-1000-LS 7.5 Nm NEMA 34 Stepper Motor - Closed Loop

The 86J1895EC-1000-LS is a 7.5 Nm NEMA 34 Stepper Motor with closed loop feedback, delivering 7.5 N·m holding torque from a 95 mm body at 6.0 A per phase. The 14 mm shaft provides a stiff output for direct coupling, and the compact length leaves more room inside equipment enclosures than longer motors in the same frame family.

closed loop Control: Removing the Assumption From Open-Loop Stepping

A conventional stepper system commands position without verifying it. If the rotor stalls under a transient overload, the controller has no way to detect the loss. This motor integrates a 1,000 P/R encoder and reports actual rotor position to the drive, which corrects any discrepancy. That eliminates the silent missed-step failure mode and lets the axis recover from brief overload rather than require a home cycle.

Speed and Torque Relationship

Holding torque is a standstill specification. As speed increases, torque drops because the winding cannot build full current within each electrical cycle. closed loop drives compensate with dynamic current control, extending the usable speed range while keeping temperature rise in check during idle phases.

Key Specifications

• Frame size: NEMA 34
• Body length: 95 mm
• Phase count: 2-phase
• Phase current: 6.0 A
• Holding torque: 7.5 N·m
• Shaft diameter: 14 mm
• Feedback: integrated 1,000 P/R encoder

Applications

As a distributor of industrial motion components, we supply this motor for CNC machine tools, packaging machinery, factory automation, precision robotic mechanisms, textile and printing machinery, food processing, and automated handling mechanisms. The 7.5 N·m rating supports geared pick-and-place and conveyor indexing where repeatable positioning matters more than peak speed.

Selection Considerations

Pair the motor with a closed loop stepper drive compatible with the 1,000 P/R encoder and the 6.0 A phase current. Because the 95 mm body is shorter than the 118 mm and 156 mm NEMA 34 variants, it offers a useful balance of torque and envelope for machine upgrades. Confirm the dynamic torque at your operating speed before finalizing the axis design.
