Description
Here’s the English version of the 8LSA46.R0045D000-0 servo motor introduction:
8LSA46.R0045D000-0 High-Performance Synchronous Servo Motor
The 8LSA46.R0045D000-0 is a premium synchronous servo motor from B&R (Bernecker + Rainer), part of the 8LS series, designed for high-precision industrial automation applications requiring compact size, high power density, and exceptional dynamic response.

8LSA46.R0045D000-0 B&R High Performance Synchronous Servo Motor
Key Features
- High Power Density
- Advanced electromagnetic design delivers high output power in a compact form factor, ideal for space-constrained applications.
- Ultra-Precision Control
- Supports high-resolution encoders (e.g., 24-bit absolute encoders) for micron-level positioning accuracy, suitable for robotics, CNC machining, and automated production lines.
- Fast Dynamic Response
- Low moment of inertia enables rapid acceleration/deceleration, perfect for frequent start-stop or high-speed reciprocating motions (e.g., packaging machinery, electronic assembly).
- Synchronous & Self-Cooled
- Synchronous motor design ensures high efficiency; self-cooling structure reduces reliance on external cooling systems, lowering maintenance costs.
- High Reliability
- IP65-rated enclosure (dust/waterproof) for harsh industrial environments.
- Withstands 3000V surge voltage without breakdown; noise level <60 dB (measured at 1 meter).
Technical Specifications
- Rated Speed: 4,500 RPM (some variants support higher speeds).
- Output Frequency: Adjustable from 0.1–120 Hz; supports V/F curve programming.
- Control Modes:
- 16 preset speed stages, 15 programmable operation stages.
- Built-in PID feedback control with time/quantity cycle control options.
- Communication Interface: RS-485 port compatible with multiple protocols (e.g., EnDAT, Hiperface, BiSS).
- Electrical Parameters:
- Output voltage: 0–300V (configurable); temperature rise: 155°C (including ambient temp).
- Compatible with B&R drives: AKD, S700 series.
Typical Applications
- Industrial Automation
- Robotic joint drives, CNC machine tool feed axes, synchronized multi-axis control in production lines.
- Energy Management
- Fan/pump systems (supports multi-motor coordination for pump staging/de-staging and automatic energy savings).
- General Industrial Equipment
- Building HVAC systems, wastewater treatment plants, municipal water supply networks.
Advantages
- Compact & Efficient: High power output in a small footprint saves installation space.
- Precise & Flexible: High-resolution encoders and multi-mode control adapt to complex motion requirements.
- Durable & Reliable: IP65 protection and vibration-resistant design ensure long-term stability under continuous operation.
- Easy Integration: Supports multiple communication protocols for seamless pairing with B&R or third-party drives.
Important Notes
- Discontinuation: This model has been discontinued. Verify stock availability or consider alternatives (e.g., 8LSA46.R2045D000-3).
- Maintenance Tips: Regularly inspect encoder connections, bearing wear, and thermal performance to ensure optimal operation.
