Product catalog summary

Overview: The BR Series AC Servomotors, known as XtraforsBR, are designed for applications requiring a high torque-to-weight ratio in a compact form. These motors are particularly suitable for direct drive use in Automated Guided Vehicles (AGVs) and exoskeletons.

Key Features:

High torque/weight ratio
Compact footprint
Available in solid and hollow shaft configurations
Reduced weight and small volume
Pancake size with a low center of gravity

Technical Specifications:

Standard version includes an incremental encoder with commutation tracks, a 10-pair poles rotor, round flange, IP 54 protection, flying leads output cables, and 48 VDC winding.
Optional programmable encoder resolutions: 1000, 1024, 2000, 2048, 4000, 4096 ppr.

Torque Curves: The document provides torque curves for different winding configurations at 48VDC, illustrating performance across various RPMs.

Mechanical Dimensions: Dimensions are provided for three models (BR-2, BR-3, BR-4) with specific measurements for components such as flange diameter and shaft length.

Technical Data:

Stall Torque: BR-2 (0.8 Nm), BR-3 (2.6 Nm), BR-4 (3.85 Nm)
Rated Speed: BR-2 (3000 rpm), BR-3 (3000 rpm), BR-4 (1500 rpm)
Rated Current: BR-2 (8.00 Arms), BR-3 (18.5 Arms), BR-4 (15.0 Arms)
EMF Constant: BR-2 (0.06 Vs/rad), BR-3 (0.08 Vs/rad), BR-4 (0.15 Vs/rad)
Winding Resistance: BR-2 (0.71 Ω), BR-3 (0.21 Ω), BR-4 (0.25 Ω)
Rotor Inertia: BR-2 (0.016 kg.m².10⁻³), BR-3 (0.105 kg.m².10⁻³), BR-4 (0.385 kg.m².10⁻³)
Mass: BR-2 (0.47 kg), BR-3 (1.2 kg), BR-4 (2.18 kg)

Global Presence: Infranor has a worldwide presence with offices and manufacturing facilities in Germany, France, China, Switzerland, Spain, Italy, and the USA.
