Description

Product Overview

The Schneider LSH-050-2-45-320/T1.1R is an LSH-series permanent-magnet synchronous servo motor associated with the Schneider Electric / LTi Drives motion-control platform. The LSH-050-2-45-320 motor designation identifies a compact servo motor with a 320 V DC-link application, 4500 rpm rated speed, and 0.45 Nm rated torque. Published LSH technical documentation lists a 0.53 Nm stall torque, 1.11 A rated current, and 0.21 kW rated power for this motor frame. The motor is intended for precise machine-axis motion where controlled acceleration, repeatable positioning, and high-speed operation are required. The exact T1.1R suffix should be checked against the motor nameplate and the original machine documentation because encoder, feedback, connector, or mechanical configuration can vary by ordering code.

Technical Specifications

The published technical catalogue gives the 4500 rpm speed, 0.45 Nm rated torque, 1.11 A rated current, 0.21 kW rated power, and 0.92 kg mass for the LSH-050-2-45-320 configuration.

Key Features and Benefits

• Compact permanent-magnet synchronous motor design for precision motion.
• 0.45 Nm rated torque with 0.53 Nm stall torque.
• 4500 rpm rated operating speed and 12000 rpm maximum permissible speed.
• Designed around a 320 V DC-link servo-drive architecture.
• Low rotor inertia supports responsive acceleration and deceleration.
• Suitable for indexing, positioning, packaging, handling, and other machine-axis applications.
• Optional brake configurations are documented for the LSH motor family.

Personally, I would verify the feedback device and suffix code before treating this motor as a drop-in spare. Servo motors with the same frame size can still differ in feedback and drive compatibility.

Installation and Maintenance

Before replacement, verify motor mounting dimensions, shaft geometry, feedback device, connector arrangement, drive compatibility, and brake configuration. Confirm that the connected servo amplifier is correctly rated for the motor’s voltage, current, and feedback requirements.

During maintenance, inspect bearings, shaft seals, connectors, feedback wiring, and motor insulation. Check for overheating, unusual bearing noise, shaft play, or encoder faults. Never exceed the documented speed or current limits. Allow the DC bus to discharge fully before disconnecting motor power, and follow the machine manufacturer’s lockout and electrical-safety procedures.

Product Warranty

Warranty depends on supplier, condition, and purchase agreement. Confirm whether the motor is new old stock, unused, refurbished, or tested surplus, and request the exact nameplate data and feedback configuration before procurement.

The Schneider LSH-050-2-45-320/T1.1R is a compact precision servo motor suited to legacy LSH/LTi motion systems, with exact suffix verification being essential for a reliable replacement.
