LTi LSH-074-2-30-320/T1 1R Servo Motor
The LTi LSH-074-2-30-320/T1 1R Servo Motor is a synchronous servo motor for industrial motion control. It belongs to the LSH motor family, which is used with compatible LTI and LUST servo drives. The motor is designed for applications requiring accurate torque, speed, and position regulation.
The type code contains important selection information. LSH identifies the motor series and mechanical size. The 074 and 2-30-320 values relate to motor length, winding, and voltage class. T1 identifies the feedback system. 1R indicates a design or option feature. These details help users match the motor to the drive, mechanics, and machine process.
Motor Design
This motor uses permanent magnet synchronous technology. The rotor has permanent magnets and no rotor winding. This design provides high efficiency, low inertia, and fast dynamic response. The stator winding is designed for operation with a servo controller that supplies controlled current and voltage. The housing supports mechanical stability and heat dissipation.
The LSH series is suitable for industrial machines with frequent acceleration and deceleration. Low rotor inertia helps the drive achieve short cycle times. The motor can be mounted in different orientations. Correct alignment between the motor shaft and the load is important. A suitable coupling should be used to limit radial and axial forces.
Feedback and Control
The T1 feedback option provides rotor position and speed information to the drive. This feedback is required for synchronous motor commutation and closed loop control. The drive uses the signal to regulate current, speed, and position. Shielded cables and proper grounding are important for signal quality. Incorrect feedback settings can cause rough running, direction errors, or drive faults.
When paired with a compatible servo drive, the motor can operate in torque, speed, and position modes. Torque mode is used for tension and force control. Speed mode supports rotary axes and conveyors. Position mode is used for indexing and synchronized motion. The drive must be configured with the correct motor data set.
Performance
The LSH-074-2-30-320/T1 1R is designed for continuous and intermittent duty. Continuous torque depends on cooling, ambient temperature, altitude, and load profile. The drive thermal model should match the motor. Overload capability is available for short periods, but the exact limits depend on the application. Proper sizing prevents overheating and extends motor life.
The motor provides smooth torque and accurate positioning when installed and tuned correctly. This is important for production processes that require repeatability and surface quality. Mechanical rigidity, coupling alignment, and drive tuning all affect final performance.
Installation
Mount the motor on a rigid surface with the correct flange. Tighten screws to the specified torque. Check coupling alignment in radial, axial, and angular directions. Avoid impact on the shaft. Connect protective earth securely. Route power and encoder cables separately. Use shielded cables for feedback and control signals.
Ensure adequate cooling around the motor. If the machine enclosure restricts airflow, additional ventilation may be required. Surface temperature can become high during operation. Provide touch protection and respect thermal limits in the machine design.
Commissioning
Before commissioning, check the nameplate data, wiring, and mechanical installation. Enter motor data into the drive. Set feedback type and verify encoder direction. Run the motor at low speed without load. Confirm direction and stopping behavior. Then tune speed and position loops. Set current limits, speed limits, and ramps. Test brake release and holding functions if applicable. Record parameters and backup the configuration.
Applications
The LTi LSH-074-2-30-320/T1 1R is suitable for packaging, printing, handling, textile, and general automation. It can control feed axes, rotary axes, and small to medium power servo applications. Its robust design and dynamic performance make it useful in modern machine concepts.
Maintenance
Inspect bearings, cables, connectors, and cooling surfaces periodically. Check for unusual noise, vibration, and temperature. Feedback connectors must be clean and secure. If the motor is replaced, update the drive parameters to match the new motor and feedback system.
In summary, the LTi LSH-074-2-30-320/T1 1R Servo Motor provides efficient synchronous servo operation. It combines robust construction, feedback based control, and high dynamic response for industrial motion systems.
