Description
LUST LSH-050-2-45-320/T1,K | 320V Servo Motor
Product Introduction
For a legacy servo replacement, the full ordering code is the starting point—not just the frame size. The LUST Electronics LSH-050-2-45-320/T1,K belongs to the LSH synchronous servo motor family. Its catalog-defined LSH-050-2 electrical configuration is rated for a 320 V DC-link, 4,500 rpm, 0.45 Nm rated torque, and 1.11 A rated current.
The LSH catalog identifies K as the resolver configuration in its motor-length data. That makes feedback compatibility a key procurement check. The comma and /T1,K notation should be preserved as shown on the supplied nameplate; do not assume it is interchangeable with a related T1-S4.1R or other suffix variant without confirming the complete configuration.

Global Sourcing & Live-Test SOP
5.1 Inbound Verification
- Photograph the full nameplate and all suffix markings.
- Confirm LSH-050-2-45-320/T1,K exactly as supplied.
- Record serial number and manufacturer identification.
- Inspect the shaft, flange, housing, and mounting holes.
- Inspect power and feedback connectors for damage or corrosion.
- Confirm whether the resolver, feedback cable, brake, or gearbox is included.
- Compare the physical assembly against the machine’s original motor.
5.2 Electrical and Mechanical Inspection
- Do not connect the motor until its power and feedback pinouts are verified.
- Inspect shaft condition and check for abnormal play or binding.
- Verify winding and insulation condition using an appropriate OEM-approved procedure.
- Avoid applying insulation-test voltage to feedback electronics or connected components unless explicitly permitted.
- Check for signs of overheating, moisture ingress, impact damage, or unauthorized repair.
5.3 Servo Drive Compatibility and Functional Test
- Identify the installed servo drive and confirm compatibility with the motor’s 320 V DC-link class.
- Verify resolver compatibility, feedback wiring, and drive parameter requirements.
- Load the correct motor data before enabling the drive.
- Secure the motor mechanically before testing.
- Perform controlled low-speed operation and verify direction, feedback recognition, and stable motion.
- Monitor current, drive alarms, abnormal vibration, and noise.
- Do not run unrestricted speed or torque tests without the applicable OEM limits and suitable test equipment.
5.4 Extended Run and Final Preparation
- Run the motor under controlled conditions appropriate to the application.
- Monitor temperature, current, feedback stability, vibration, and drive faults.
- Record test duration, drive model, parameter set, and observed results.
- Preserve the complete nameplate and serial information in the inspection record.
- Protect the shaft, connectors, and mounting face during shipment.
- Use suitable industrial packaging and accurately identify the item’s actual condition.
Field Engineer’s Pitfall Guide
❗ Do not discard the ,K suffix
The LSH catalog associates K with the resolver configuration. Confirm the feedback type and full ordering code before accepting a similar-looking motor as a replacement.
❗ The 320 V designation is a DC-link class—not a mains connection instruction
The motor must be operated through a compatible servo drive. Do not connect it directly to AC mains or infer drive compatibility from voltage alone.
❗ Confirm the full option code before substituting a related LSH motor
A related -45-320/T1-S4.1R is documented with the same core electrical class, but that does not establish complete interchangeability with -45-320/T1,K. Check feedback, shaft, mounting, and any option differences against the original machine.
Intent-Driven FAQ
We LUST /T1,K?
It is an LSH-series synchronous servo motor intended for industrial motion-control applications.
What are its rated speed and torque?
The documented configuration is rated at 4,500 rpm and 0.45 Nm. Confirm the exact nameplate before final application sizing.
What does the K suffix mean?
The LSH catalog uses K for the resolver-equipped configuration in its motor-length data. Verify the full order code and feedback details on the actual motor.
Can it replace another LSH-050 motor?
Not automatically. Compare the full part number, feedback configuration, electrical ratings, shaft dimensions, mounting, and drive compatibility.
Can the motor connect directly to 320 VAC?
No. The 320 V designation refers to the DC-link voltage class. The motor requires a compatible servo drive and the correct commissioning parameters.
Is this motor obsolete?
The LSH family is a legacy LUST/ LT i motor range, and related variants appear in surplus listings. Current lifecycle status and availability for the exact /T1,K variant should be confirmed with the supplier.
What should buyers verify before ordering?
Request a clear nameplate photograph, complete suffix, serial number, connector and shaft photos, feedback details, and written confirmation of condition and test status. Confirm compatibility with the installed drive before purchasing.
Bottom Line for Buyers
The Lronics /T1,K is an synchronous servo motor associated with a 320 V DC-link class, 4,500 rpm rated speed, and 0.45 Nm rated torque. The K resolver designation is an important configuration detail.
For replacement procurement, preserve the complete suffix and verify feedback, shaft and flange dimensions, and drive compatibility. A matching LSH frame size alone is not sufficient evidence of a drop-in replacement.
