High-Speed Servo Performance for Modern Automation
In today's fast-paced manufacturing environment, achieving precise motion control at high speeds is essential. The B&R 8LSC46.ee060ffgg-4 three-phase synchronous servo motor addresses this need with a nominal speed of 6000 rpm and a maximum speed of 6600 rpm. This motor is designed for applications that demand excellent dynamic characteristics, positioning precision, and compact size.
With a nominal torque of 7.7 Nm and a stall torque of 13.0 Nm, the 8LSC46.ee060ffgg-4 provides robust performance for a variety of industrial tasks. Its large overload capacity, reflected in a maximum torque of 38.0 Nm, ensures that the motor can handle peak loads without compromising stability. This makes it a reliable choice for high-throughput production lines.
Key Technical Specifications
The 8LSC46.ee060ffgg-4 is engineered with precision in mind. Its torque constant of 0.81 Nm/A and voltage constant of 49.22 V/1000rpm indicate efficient energy conversion. The stator resistance is 0.53 Ohm, and the stator inductance is 4.3 mH, contributing to a fast electrical time constant of 8.0 ms. These parameters ensure responsive control and minimal delay in dynamic operations.
The motor's moment of inertia is 4.0 kg·cm², and its mass without brake is 8.64 kg. For applications requiring a holding brake, the optional brake provides a holding torque of 15 Nm and adds 1.00 kg to the mass. The motor's thermal time constant is 27 minutes, and it is rated for continuous operation (S1) per EN 60034-1, with insulation class F per IEC 60085.
Applications in High-Speed Manufacturing
The 8LSC46.ee060ffgg-4 is well-suited for applications such as packaging machinery, textile processing, and material handling systems. In a typical packaging line, the motor's high speed and precise positioning enable rapid and accurate product placement, reducing cycle times and increasing throughput. Its compact design allows for easy integration into space-constrained equipment.
For robotics and assembly automation, the motor's excellent dynamic characteristics and overload capacity ensure smooth and reliable operation even during rapid acceleration and deceleration. The optional single-cable (hybrid) solution simplifies wiring, reducing installation time and potential points of failure. This motor is a versatile choice for OEMs seeking to enhance machine performance.
Integration with ACOPOS Drives
The 8LSC46.ee060ffgg-4 is designed to work seamlessly with B&R ACOPOS servo drives, specifically the recommended drive model 024X. This integration ensures optimal performance and simplifies system commissioning. The motor supports resolver or EnDat feedback systems, including safety-related variants, providing flexibility for various control architectures.
For functional safety, the motor can be equipped with encoders that support safe motion monitoring. Safe Torque Off (STO) is implemented via the ACOPOS servo drive, enhancing operator safety without adding complexity to the motor. This makes the 8LSC46.ee060ffgg-4 a suitable choice for applications requiring safety-rated motion control.
Environmental and Mounting Considerations
The motor operates in ambient temperatures from -15°C to +40°C, with a maximum of +55°C, and can be derated at higher elevations. It has an IP64 protection rating per EN 60034-5, with the fan rated IP20. For harsher environments, an optional oil seal can upgrade the protection to IP65. The motor is designed for horizontal mounting (IM 3001) and other configurations per EN 60034-7.
Compliance with LVD 2014/35/EU, EMC 2014/30/EU, and RoHS 2011/65/EU ensures that the motor meets European safety and environmental standards. It is not C-UR-US listed, but it conforms to EN 60034-1/7/11/14. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
