8JSA54.R0028D900-0
The B & R Automation 8JSA54.R0028D900-0 is a high-precision three-phase synchronous motor from the 8JS Synchronous Motors series, engineered for demanding industrial automation tasks. This permanent-magnet motor delivers a rated torque of 5.0 Nm and achieves a nominal speed of 2750 RPM, ensuring consistent power output. Designed for continuous operation (EN 60034-1 S1), it operates within a protected environment class of IP65 with oil seal (EN 60034-5), making it ideal for harsh factory conditions where dust and moisture resistance are critical.
Incorporating a resolver feedback system with 10' accuracy and 981 m/s² shock tolerance, this motor ensures precise angular positioning and rapid response to control commands. The star-connected three-phase winding supports a rated current of 4.3 A, optimizing energy consumption and thermal stability. Its self-cooling method via mounting flange and high peak torque for transient loads provide robust overload capability. The motor’s dynamic performance is characterized by optimized torque ripple and high dynamic torque, enabling smooth acceleration and deceleration in high-speed conveyor or robotic applications.
The 8JSA54.R0028D900-0 features a keyed shaft and swivel connector for reliable cable orientation and electrical insulation, minimizing installation complexity and EMI interference. Rated for an operating temperature range of 5 °C to 40 °C, it maintains performance across standard industrial climates. Plug-and-play integration with B&R drives allows seamless parameterization and system integration, reducing setup time. Built for continuous 24/7 operation with exceptional shock resistance and low power consumption, this motor enhances productivity and extends maintenance intervals, delivering unmatched efficiency and reliability in automation, robotics, and material handling systems.
