Its robust construction and high power density make it a practical solution for machine axes where performance and reliability are important.

Series and Model Identification

The LST series is part of the LUST LTi DRiVES motor portfolio. The model designation LST-097-3-30-560/T1.1R includes information about the frame size, winding, speed class, and voltage class. The 097 indicates the frame size, while the 3 refers to the winding variant. The 30 indicates the speed class, and 560 defines the DC bus voltage compatibility. The T1.1R suffix refers to the feedback and connection configuration, including the RE15-1-A14 resolver. This identification helps users match the motor to the correct servo drive and mechanical system.

Motor Design and Construction

The motor uses rare earth permanent magnets in the rotor. This design eliminates the need for rotor excitation and contributes to high efficiency and high torque density. The stator winding is designed for low losses and good thermal behavior. The housing provides mechanical protection and effective heat dissipation. The shaft and flange are manufactured for stable mechanical integration with gearboxes, pulleys, and other machine elements. The resolver is mounted to provide accurate rotor position information across the full speed range.

Electrical Characteristics

The LST-097-3-30-560/T1.1R is designed for operation with a servo drive that provides field oriented control. The motor can deliver high peak torque for short periods, enabling fast acceleration and deceleration. The rated torque of 5.3 Nm provides sufficient force for medium and high load axes. The rated speed of 3000 rpm supports rapid traverse movements and short cycle times. The 560 VDC bus voltage is compatible with modern servo drives that operate from a rectified three phase supply.

Feedback and Control Compatibility

The motor is equipped with an RE15-1-A14 resolver. The resolver provides rotor position and speed information to the servo drive. This information is essential for accurate commutation and precise motion control. The resolver is known for robustness and reliability in industrial environments. The feedback interface must match the drive configuration. Motor temperature sensors can be connected to protect against overheating. Feedback parameters are configured during commissioning.

Thermal Management

Thermal performance is a critical factor in servo motor selection. The LST-097-3-30-560/T1.1R is designed to manage heat generated during continuous and intermittent operation. The winding insulation system is suitable for standard industrial ambient conditions. When the motor is mounted on a metal machine frame, additional heat can be transferred through the flange. In applications with high duty cycles, forced air cooling or liquid cooling may be considered, depending on the specific motor variant and operating conditions.

Mechanical Integration

The motor shaft and flange dimensions are designed for standard mechanical interfaces. Coupling to the load should be aligned carefully to avoid radial and axial forces that could damage bearings. The motor can be mounted in horizontal or vertical orientation, provided that lubrication and sealing requirements are observed. The power and feedback connectors are positioned for convenient cable routing in the control cabinet or machine frame.

Dynamic Performance

High dynamic response is achieved through a low rotor inertia and a magnetic circuit that supports rapid current changes. This allows the motor to follow complex motion profiles with minimal lag. The drive can implement position, velocity, and torque control modes. In multi-axis systems, the motor can be synchronized with other axes for coordinated motion, such as in gantry systems, rotary tables, and interpolating machine tools.

Applications

The LST-097-3-30-560/T1.1R is suitable for applications such as packaging machines, labeling systems, printing presses, textile machinery, and automated assembly lines. It can be used for feed axes, positioning tables, winding drives, and tool changers. Its 5.3 Nm rating makes it appropriate for medium and high load axes, while the 3000 rpm speed supports fast positioning. The motor is also suitable for applications requiring frequent starts and stops, where peak torque and thermal capacity are important.

Installation and Commissioning

Correct installation begins with mechanical alignment and secure mounting. The motor cables should be shielded and connected according to the drive manufacturer instructions. The feedback cable should be routed separately from power cables to reduce interference. During commissioning, motor parameters such as pole count, rated current, torque constant, and resolver resolution must be entered into the servo drive. Autotuning functions can help optimize control loop gains, but manual adjustment may be required for demanding applications.

Maintenance and Reliability

The motor requires minimal maintenance under normal operating conditions. Bearings are the primary wear component, and their condition can be monitored through vibration and temperature measurements. The motor should be kept clean and free from excessive dust or moisture. If the motor is used in harsh environments, proper sealing and protection should be verified. Regular inspection of cables and connectors helps prevent intermittent faults.

Selection Considerations

When selecting the LST-097-3-30-560/T1.1R, users should verify the required torque and speed, the available bus voltage, the feedback type, and the mechanical interface. The motor should be matched to the load inertia for stable control. The drive must be capable of supplying the required continuous and peak current. In applications with high radial or axial loads, an appropriate bearing or gearbox arrangement should be used.

Conclusion

The LUST LTi DRiVES LST-097-3-30-560/T1.1R is a powerful and efficient servo motor that provides 5.3 Nm of rated torque at 3000 rpm with 560 VDC bus compatibility. Its RE15-1-A14 resolver feedback supports precise commutation and reliable operation. With correct selection and commissioning, it contributes to productive and accurate machine performance.
