B&R 8LSA46.R0045D000-0 Synchronous Servo Motor
The B&R 8LSA46.R0045D000-0 is a three-phase synchronous servo motor from B&R's 8LSA series — a family of permanent-magnet synchronous motors designed for high-precision, high-dynamics motion control. The 8LSA series is used with B&R's ACOPOS drive systems and is characterised by compact construction, high torque density and excellent dynamic performance for demanding automation and machine applications.
- B&R 8LSA synchronous servo motor
- Permanent-magnet, three-phase design
- Size 4 frame, length 6
- Resolver (R) feedback
- For use with B&R ACOPOS drive systems
- Order number: 8LSA46.R0045D000-0
Key Features & Functions
High Power Density
Compact design with minimal weight and favourable torque-to-size ratio, allowing space-efficient drive solutions.
Outstanding Dynamics
Fast axis response and high overload capability suit applications requiring rapid, precise positioning.
Sinusoidal Commutation
Permanent-magnet rotor with three-phase star-connected windings provides smooth, dynamically strong torque with optimised torque ripple.
Resolver Feedback
The “R” in the order number denotes resolver (rotary transformer) feedback, used for robust position and speed feedback.
B&R ACOPOS Integration
Designed for use with B&R ACOPOS drive systems for precise torque and speed regulation.
Industrial Construction
Self-cooling, flange-mounted design with the robustness required for continuous industrial operation.

Frequently Asked Questions
What is the B&R 8LSA46.R0045D000-0?
It is a three-phase permanent-magnet synchronous servo motor from B&R's 8LSA series, designed for high-precision, high-dynamics motion control with ACOPOS drive systems.
What does the order number tell us?
In B&R's 8LS order key: 8LSA = self-cooled, slim design; 4 = motor size; 6 = motor length; R = resolver feedback; 0045 = 4500 rpm nominal speed; D000 = standard configuration.
What torque and power does it deliver?
Torque and power figures vary by configuration and could not be confirmed from an official B&R datasheet. Please verify against B&R documentation before ordering.
Which drive is it used with?
The 8LSA series is designed for use with B&R ACOPOS drive systems. Confirm the correct drive selection using B&R's configuration tools.
Does it have a holding brake?
The “D000” suffix indicates a standard configuration without a holding brake. Confirm requirements against the official B&R datasheet.
Where can I find the official datasheet?
Official technical documentation is available from B&R Industrial Automation and authorized distributors. Verify all specifications there before purchase.
