Its stall torque is 15.6 Nm, with a stall current of 9.6 A, indicating strong starting performance. The maximum torque reaches 45.6 Nm, supported by a maximum current of 44.0 A, allowing for rapid acceleration and deceleration.

The motor's torque constant is 1.63 Nm/A, and the voltage constant is 98.44 V/1000rpm, ensuring efficient energy conversion. With a stator resistance of 1.66 Ohm and inductance of 14.1 mH, the electrical time constant is 8.5 ms, contributing to quick response times. The thermal time constant of 27 minutes helps in managing heat buildup during prolonged use.

For applications requiring precise positioning, the motor offers a moment of inertia of 4.8 kg·cm² and a mass of 9.55 kg (without brake). An optional brake provides a holding torque of 15 Nm, adding 1.00 kg to the mass and 1.66 kg·cm² to the inertia. The motor is designed for continuous operation (S1) per EN 60034-1, with insulation class F (IEC 60085).

Real-World Applications and Use Cases

The 8LSC47.ee030ff00-4 is ideal for applications that demand high dynamics and precision. In packaging machinery, for example, the motor's rapid acceleration and deceleration capabilities enable faster cycle times without compromising accuracy. Its compact size allows for space-saving machine designs, which is a critical factor in modern production lines.

Another common use is in material handling systems, where the motor's high overload capacity ensures reliable operation even under variable loads. The single-cable (hybrid) solution option simplifies installation and reduces wiring complexity, which is particularly beneficial in multi-axis systems. The encoders for functional safety enhance machine safety, meeting the requirements of modern safety standards.

In a typical automotive assembly line scenario, the 8LSC47.ee030ff00-4 can drive a conveyor system that requires precise speed control and frequent starts and stops. The motor's ability to deliver high torque at low speeds, combined with its dynamic response, ensures smooth and efficient material flow. This hypothetical example illustrates how the motor's specifications translate into tangible operational benefits.

Compatibility and Integration with ACOPOS Drives

For optimal performance, the 8LSC47.ee030ff00-4 is recommended to be paired with ACOPOS servo drives, specifically the 013X model. This combination ensures seamless integration and maximizes the motor's capabilities. The motor supports resolver (R0/R2) or EnDat feedback systems, including inductive and optical variants, with safety-related options available.

The motor features built-in plug-in connectors and a single-cable (hybrid) solution, which reduces cabling and installation time. The connector size/type is designated as '1', and the cable cross-section is 0.75 mm². This integration-friendly design helps engineers streamline their machine builds and reduce potential points of failure.

Business Value and ROI Considerations

Investing in the 8LSC47.ee030ff00-4 can lead to significant long-term savings. Its high efficiency and dynamic performance reduce cycle times, increasing throughput. The robust construction and thermal management extend the motor's lifespan, minimizing downtime and maintenance costs.

Furthermore, the motor's compliance with LVD 2014/35/EU, EMC 2014/30/EU, and RoHS 2011/65/EU ensures it meets European standards, facilitating easier machine certification. The optional encoders for functional safety can simplify safety system design, potentially reducing overall system costs. These factors contribute to a lower total cost of ownership.
