Its compact and lightweight construction helps reduce machine footprint and inertia, contributing to faster cycle times.
Technical Specifications and Performance Analysis
Let's examine the key technical parameters that define the 8LSC44.ee030ff00-4's capabilities. The motor delivers a nominal power of 2205 W and a nominal current of 4.3 A, making it a robust choice for medium-duty applications. Its stall torque of 8.5 Nm and stall current of 5.2 A indicate a strong overload capacity, allowing the motor to handle short-term peak loads without issues.
The motor's dynamic performance is further enhanced by a maximum torque of 22.8 Nm and a maximum current of 21.9 A. This high overload capability is essential for applications that require quick acceleration or deceleration, such as in pick-and-place machines or packaging equipment. The torque constant of 1.63 Nm/A and voltage constant of 98.44 V/1000rpm provide predictable performance for precise control.
With a stator resistance of 3.78 Ohm and stator inductance of 29.1 mH, the motor's electrical characteristics are well-defined for servo drive tuning. The electrical time constant of 7.7 ms and thermal time constant of 25 min indicate how quickly the motor responds to control signals and how it manages heat. The moment of inertia is 2.6 kg·cm², and the motor mass is 6.82 kg (without brake), contributing to a favorable power-to-weight ratio.
Application Scenarios in Modern Manufacturing
The 8LSC44.ee030ff00-4 is versatile enough for a range of industrial applications. In a typical packaging line, this motor can drive the film feed rollers, providing the precise tension and speed control needed to maintain consistent seal quality. Its high overload capacity ensures it can handle the intermittent loads of cutting and crimping operations without stalling.

In the electronics assembly sector, the motor's compact size and high positioning accuracy make it ideal for component placement machines. The ability to integrate with encoders for functional safety is a significant advantage in applications where human-machine interaction is frequent, such as collaborative assembly cells. The motor's single-cable (hybrid) solution option simplifies wiring and reduces installation time, which is a practical benefit for machine builders.
Another key application is in material handling and robotics. The 8LSC44.ee030ff00-4 can be used in the axes of a delta robot or a gantry system, where its dynamic response and low inertia enable fast and accurate movements. The motor's IP64 protection rating (per EN 60034-5) makes it suitable for environments with dust and light moisture, though the fan is rated IP20.
Integration with ACOPOS Drives and System Compatibility
For optimal performance, the 8LSC44.ee030ff00-4 is designed to work seamlessly with B&R ACOPOS servo drives. The recommended drive series is 8X8X, which provides the necessary control algorithms and feedback processing to fully exploit the motor's capabilities. The motor supports both resolver and EnDat feedback systems, including safety-related variants, allowing for flexible integration into different control architectures.
The motor's feedback options include 32-line single-turn or multi-turn encoders, which deliver high-resolution position data for precise motion control. The built-in plug-in connectors simplify installation and maintenance. Additionally, the single-cable (hybrid) solution combines power and feedback in one cable, reducing wiring complexity and potential points of failure.
When integrating the motor, it is important to consider the environmental conditions. The motor operates in a temperature range of -15 to +40 degrees Celsius (max +55 degrees Celsius) and can be derated at higher temperatures or altitudes. The maximum elevation is 2000 meters, and the flange temperature should not exceed 65 degrees Celsius. These parameters ensure reliable operation in most industrial settings.

Business Value and ROI Considerations
Investing in the 8LSC44.ee030ff00-4 can yield significant business benefits. Its high overload capacity reduces the risk of motor stalling, which minimizes unplanned downtime and maintenance costs. The motor's energy efficiency, thanks to its permanent-magnet design, can lower operational energy consumption compared to older induction motors.
The compact and lightweight design also contributes to lower machine construction costs, as smaller frames and mounts can be used. The availability of a single-cable solution reduces installation labor and material costs. For machine builders, the motor's compatibility with ACOPOS drives simplifies system engineering and reduces commissioning time, leading to faster time-to-market.
From a total cost of ownership perspective, the 8LSC44.ee030ff00-4 offers a compelling value proposition. Its robust construction and high-quality materials ensure a long service life, reducing replacement frequency. The motor's compliance with standards such as LVD 2014/35/EU, EMC 2014/30/EU, and RoHS 2011/65/EU ensures it meets regulatory requirements, avoiding potential compliance issues.
