The exact part number is also listed by industrial automation suppliers as a 3-phase, 3000 RPM, 560 V-class servo motor with self-cooling and holding brake. Because different sources present the voltage differently, the physical nameplate should be treated as the final reference for electrical commissioning.
๐ญ Typical Applications
The 8LSA78.R2030D600-3 is suitable for industrial machinery where high torque, controlled positioning, and repeatable servo motion are required.
Typical applications include:
- Industrial machine tools
- Automated production equipment
- Packaging machinery
- Material-handling systems
- Robotics and positioning equipment
- High-load motion axes
- CNC and precision machinery
- Industrial automation systems
Its IP65 protection makes the motor suitable for applications where protection against dust and water jets is required, provided the complete installation environment remains within the manufacturer’s operating limits.
๐ Identification References
When checking this motor against an existing installation, the following markings are useful:
- 8LSA78.R2030D600-3
- AB180-S2-P2
- Rev. C8
- 3000 RPM
- 400 V
- 27 A
- 44 Nm
- IP65
- E235396
- M5Z11 417143
The AB180-S2-P2 designation is also used for planetary gearheads, so buyers should confirm whether their requirement is for the complete motor/gearhead assembly or for a particular mechanical component.
โ Frequently Asked Questions
Q1: What is the rated speed of the 8LSA78.R2030D600-3?
The listed rated speed is 3000 RPM.
Q2: What is the rated torque?

๐ Compatibility & Ordering Notes
For replacement applications, compare the complete motor identification rather than matching only the 3000 RPM rating.
Recommended checks include:
- Motor part number: 8LSA78.R2030D600-3
- Motor model: AB180-S2-P2
- Revision: C8
- Rated voltage and current
- Rated and peak torque
- Brake configuration
- Shaft and gearbox dimensions
- Gear ratio
- Encoder/feedback arrangement
- Motor connector configuration
- Compatible B&R servo drive
Because this is a large servo motor assembly, the physical mounting dimensions and shaft/gearhead interface are especially important when replacing an installed unit.
For the referenced item, the seller listing identifies the condition as Used and the approximate weight as 80.2 kg.
