LC57H380+LCDA357H: delivery record
On this page
This delivery pairs a Lichuan LC57H380 three-phase closed-loop stepper motor with an LCDA357H drive. The motor label visible in the second photograph states 2.0 N·m and 3.5 A. The supply note explicitly calls the 2 N·m value holding torque, so it should not be presented as verified running torque at the source description's 1500 rpm.
Identification and delivery details
The December 11, 2025 note records one new, original motor/drive pairing with a one-year warranty and a 2.5 kg weight entry. The first photograph shows a square-flange motor, exposed output shaft, attached cables and the blue drive with green terminals beside Lichuan packaging.
The drive face separates VCC, Motor, Encoder and control-signal terminal groups and carries a printed setting table. These labels support identification of the interfaces; the reviewed views do not establish the complete supply range, pin mapping or selected settings clearly enough to reproduce them as a wiring specification.
The second photograph shows the motor side label partly covered by cables and the drive's mounting underside. The LC57H380, three-phase closed-loop stepper wording, 2.0 N·m and 3.5 A entries are visible. The current belongs to the motor label and is not a measured drive input current.
The 2.5 kg source weight has no stated basis. No loaded speed/torque curve, positioning test or cost comparison is documented, so the description's 1500 rpm and 45% savings claims are not treated as results for this supplied pair.

Photographs 1 and 2 were reviewed. Fourteen further images and one video are retained without individual visual review. The archive does not document motion performance under a defined load.
Matching this part
Compare the motor and drive as a supported pair, including full labels, motor phase wiring, feedback connector and cable length. Check flange, shaft and mounting dimensions against the installed mechanism.
Obtain the exact drive supply and command-interface specification before connecting it. Set motor current and motion parameters from the applicable motor/drive documentation; holding torque cannot substitute for a torque-speed curve at the required speed.
