8KSL94.ee010ff00-h | B&R 37 kW 355 Nm Servo Motor

Product Overview of the 8KSL94.ee010ff00-h

The B&R 8KSL94.ee010ff00-h is a high-torque three-phase synchronous servo motor from the 8KS series. Its permanent-magnet design with optimized external ventilation produces very high torque and power density. Therefore, it suits demanding general machine manufacturing tasks. The motor runs on the ACOPOS 1650 servo drive, which implements STO for functional safety.

Reliability and Service from a Maintenance Perspective

The 8KSL94.ee010ff00-h is virtually maintenance-free by design. Its external ventilation uses an independent axial fan module rated IC 416, with airflow direction A to B. A KTY84-130 thermal protector monitors winding temperature, with a maximum of 155 degC. The thermal time constant is 43.9 minutes, so the motor tolerates short overloads without rapid heating. Bearing life reaches LH10 20,000 hours under specified conditions. Furthermore, the resolver and EnDat 2.1 or 2.2 feedback options support functional safety encoders. For maintenance engineers, this means fewer unplanned stops and predictable service intervals.

Installation and Environmental Limits

Mount the motor horizontally per IM B5 or IM B35. The FF flange follows IEC, the shaft end follows DIN 748, and the key follows DIN 6885-1 Form A. Balancing meets DIN ISO 8821, runout meets DIN 42955 N, and the coating is water-based RAL 9005. The motor operates in class 3K3/3Z12 at 0 to +40 degC, with relative humidity of 5 to 85 percent and maximum elevation of 1000 m. It carries IP54 protection. Vibration resistance is 3 g radial and 1 g axial across 10 to 55 Hz. The fan module produces 74 to 78 dB(A) at 400 VAC.

Applications and Integration

This servo motor fits general machine manufacturing applications that demand high overload capacity. Typical uses include heavy-duty presses, extruders, and large material handling axes. Because the motor pairs with the ACOPOS 1650 drive, integration into the motion control system is straightforward. The terminal box handles power connections, while speedtec or ITEC connectors handle encoder feedback. For precise electrical specifications, contact AutoDCSTech with your exact requirements.
