The 86J12126EC-1000-60 is the short-body member of the NEMA 34 closed-loop family, measuring 126 mm with 6.8 N·m holding torque. It is specified when a machine has tight axis space but still needs the load capacity of the NEMA 34 frame.
Feedback comes from an integrated 1,000 P/R encoder. The control loop continuously compares commanded position with actual rotor position, which removes the need for the conservative acceleration limits that open-loop steppers impose. The result is faster moves with deterministic positioning.
Rated phase current is 3.0 A. The motor’s high efficiency and low heat generation simplify thermal management inside enclosures, while the low-noise, low-vibration profile suits machines that run near operators or in laboratory-adjacent settings.
Desktop CNC routers, motion control systems, and compact factory automation benefit from the balance of torque, length, and closed-loop reliability. It is also common in printing and food processing equipment where indexing precision matters more than peak speed.
