3.0 N·m Closed Loop Stepper Motor with 1000P/R Encoder, 57 mm Integrated Unit

Product Overview

The iESSC57-36-30 is a 3.0 N·m Closed Loop Stepper Motor in a 57 mm frame with a 100 mm body length. Because the drive stage and the motor share one housing, machine builders can eliminate the separate driver cabinet and shorten the power path between the output stage and the winding.

closed loop Operation

Position feedback is taken from a 1000 P/R incremental encoder on the shaft. The control loop compares the commanded step position with the measured shaft angle and compensates in real time, so the unit does not depend on open-loop step counting alone. This reduces the risk of missed steps during rapid acceleration and improves holding when load torque fluctuates.

Torque and Thermal Characteristics

With 3.0 N·m holding torque, the motor covers axis loads typical of small machine tool feed stages and indexing stations. The integrated drive is tuned to keep heat generation low during dwell periods, which is useful in enclosures where several drives run together. Low vibration and fast acceleration result from the closed loop control behavior rather than from over-driving the winding current.

Specification Summary

• Frame size: 57 mm
• Body length: 100 mm
• Holding torque: 3.0 N·m
• Rated current: 4.0 A
• Feedback: 1000 P/R incremental encoder

Why an Integrated Closed Loop Helps

The closed loop design is well suited to applications that see changing loads or frequent direction changes, where an open-loop stepper might lose steps. Because the encoder confirms the shaft reached its commanded position, the machine can run with greater confidence at higher speeds.

Where It Fits

The unit is regularly applied in CNC machine tools, packaging machinery, industrial automation transfer lines, precision robotic mechanisms, textile and printing stations, food processing equipment, and automated handling mechanisms.

Selection Considerations

Confirm the supply can deliver the 4.0 A rated current and that the 100 mm body fits the mounting space. Since the encoder is incremental, plan a home reference if the application needs absolute orientation.
