16 N·m Closed Loop Stepper Motor - NEMA 42 with Integrated Encoder

16 N·m Closed Loop Stepper Motor in a Balanced NEMA 42 Frame

The 110J12160EC-1000 is a 16 N·m Closed Loop Stepper Motor rated at 16 N·m holding torque with a 160 mm body length and 6.0 A phase current on a 19 mm shaft. It is a medium-length variant of the 110 mm frame family, offering a balance between available torque and axial space in the machine envelope.

How the Integrated Encoder Works

The motor carries an integrated 1,000 P/R encoder that feeds rotor position back to the drive. This feedback path eliminates the open-loop failure mode where steps are lost and never detected: position error is measured and corrected in real time, which is particularly useful when load varies with temperature or material thickness.

Speed, Response, and Vibration

As a three-phase design, the motor produces lower vibration and smoother motion at speed than an equivalent two-phase unit. It runs with high efficiency and low noise, and closed loop control extends the useful speed range beyond what a conventional stepper achieves without losing synchronism.

Where It Fits

Applications in factory automation, food processing, and precision robotic mechanisms benefit from the motor’s ability to hold position under load while keeping the control architecture simple. For vertical or gravity-loaded axes, consider the brake variants of the same frame. Lyenwsin can supply this 16 N·m Closed Loop Stepper Motor with a matched closed loop drive and support for commissioning.

Duty and Thermal Planning

The 6.0 A rating gives a useful margin on medium-torque axes while keeping drive sizing economical. Verify the mounting surface is flat and rigid so the 19 mm shaft transmits torque without flex, and allow airflow around the body on long production runs.
