Performance Analysis: Torque, Speed, and Dynamics
The 8LSC45.ee030ff00-4 delivers a nominal torque of 8.8 Nm at 3000 rpm, with a stall torque of 10.4 Nm. This overload capacity allows the motor to handle peak loads without compromising continuous operation. The torque constant of 1.63 Nm/A indicates efficient torque generation per ampere, which can contribute to energy savings.
With a maximum speed of 6600 rpm, the motor offers a wide speed range. The electrical time constant of 7.8 ms and thermal time constant of 26 minutes provide insight into its dynamic and thermal behavior. For applications requiring rapid cycling, the low inertia and high torque enable fast acceleration and deceleration, improving overall throughput.
The motor's design includes optimized torque rippling for good controllability. This feature is essential for applications demanding smooth motion, such as precision machining or robotic axes. The permanent-magnet synchronous design ensures high efficiency and precise speed control.
Integration and Compatibility with ACOPOS Drives
For seamless integration, the 8LSC45.ee030ff00-4 is recommended for use with ACOPOS servo drives from B&R, specifically the 8X8X series. This pairing ensures optimal performance and simplifies commissioning. The motor supports single-cable (hybrid) solutions, which combine power and feedback in one cable, reducing wiring complexity and installation time.
Feedback options include resolver or EnDat encoders, with safety-related variants available. The motor features built-in plug-in connectors for easy installation. The single-cable option is particularly beneficial in applications with limited space or where minimizing cabling is a priority.
The motor's compliance with LVD 2014/35/EU, EMC 2014/30/EU, and RoHS 2011/65/EU ensures it meets European regulatory standards. It is not C-UR-US listed, so for North American installations, verify local requirements. The motor conforms to EN 60034-1/7/11/14 standards, covering rating, mounting, and vibration.
Application Scenarios: Where This Motor Excels
The 8LSC45.ee030ff00-4 is well-suited for applications that demand high dynamics and precision. In packaging machinery, for example, the motor can drive servo-controlled cutters or feeders that require rapid indexing and accurate positioning. The high overload capacity ensures reliable operation even during momentary peak loads.
In material handling systems, the motor's compact size and reduced weight facilitate integration into space-constrained equipment. The externally fan-cooled design (IC4A0A6) allows continuous operation in ambient temperatures up to 40°C, with derating above that. For applications at higher elevations, note that the motor is rated for up to 2000 meters, with derating of 5% per 1000 meters.
Another typical use is in printing presses, where the motor's low torque ripple contributes to consistent print quality. The availability of safety-rated encoders supports functional safety applications, such as safe stop functions when paired with ACOPOS drives. This makes the motor a flexible choice for modern, safety-conscious machinery.
Environmental and Mounting Considerations
The motor is rated IP64 per EN 60034-5, providing protection against dust and water splashes. The fan is IP20, but with an optional oil seal, the motor can achieve IP65. This makes it suitable for washdown environments, though you should verify the specific requirements of your application.
Mounting options include IM 3001 (horizontal), IM 3011, and IM 3031 per EN 60034-7. The flange is DIN 42948 Form A, and the shaft end is DIN 748 Form E, ensuring compatibility with standard couplings and pulleys. The motor's coating is water-based RAL 9005, which is environmentally friendly.
Operating temperature range is -15 to +40°C, with a maximum of +55°C. Storage and transport temperature range is -20 to +60°C, with humidity up to 90% non-condensing. These specifications help you plan for various installation environments.
