Product Overview of the 8KSL85.ee030ff00-h
From a maintenance engineer's perspective, the 8KSL85.ee030ff00-h is a permanent-magnet three-phase synchronous servo motor built for continuous duty. Its external axial fan module keeps the winding within thermal limits, which reduces the risk of insulation degradation over long production runs. The terminal box simplifies field wiring, and the resolver or EnDat feedback options support functional safety when paired with an ACOPOS servo drive.
Technical Specifications of the 8KSL85.ee030ff00-h
- Nominal speed: 3000 rpm for steady production cycles.
- Nominal torque: 155 Nm at continuous rating.
- Nominal power: 48695 W for high-demand machinery.
- Nominal current: 90 A at rated load.
- Stall torque: 215 Nm for holding and start-up.
- Maximum torque: 505 Nm for peak acceleration.
- Maximum speed: 4300 rpm for fast positioning.
- Torque constant: 1.79 Nm/A for current-loop tuning.
- Stator resistance: 0.046 Ohm per phase.
- Stator inductance: 1.74 mH per phase.
- Electrical time constant: 45 ms published value.
- Thermal time constant: 25 min for overload budgeting.

These verified values allow precise drive sizing and current-loop setup. Note that the published electrical time constant of 45 ms differs from the L2ph/R2ph ratio by about 19 percent; allow roughly 10 percent margin during tuning.
Reliability and Maintenance Perspective
Because the motor is virtually maintenance-free, the main wear points are the fan module bearings and the shaft-end seal. Inspect the axial fan for dust buildup every 2000 operating hours, and verify the KTY84-130 thermal sensor reading against the drive. The insulation class F and maximum winding temperature of 155 degC provide headroom, but sustained overloads above the 25-minute thermal time constant will shorten service life. Bearing life is rated at LH10 20,000 hours under specified load conditions. Radial force limits depend on speed; consult the Fr-versus-speed diagrams before adding belt or gear loads.
Installation and Environmental Notes
Mount the 8KSL85.ee030ff00-h horizontally per IM B5 or IM B35. The FF flange, DIN 748 shaft end, and DIN 6885-1 Form A key ensure mechanical compatibility with standard machine interfaces. Cooling airflow follows direction A to B, so keep intake and exhaust paths clear. The IP54 rating suits dusty or humid plant environments within 5 to 85 percent relative humidity and 0 to +40 degC ambient. Maximum elevation is 1000 m. Vibration tolerance is 3 g radial and 1 g axial from 10 to 55 Hz.
Integration with ACOPOS Drives
The motor connects to ACOPOS servo drives through the terminal box for power and via speedtec or ITEC for encoder feedback. STO is implemented by the drive, not the motor, so safety wiring must follow the drive manual. When integrating into a fieldbus network, confirm gateway and cable requirements with the supplier.
