Brushless Motors

Specifications

TThe BR serie servomotors has been designed to offer the highest dynamic performance and the maximum flexibility. The Boron Iron Neodymium magnets with high energy production allow to get a motor with high specific power, bearing high overload without any risk of demagnetization. The magnetic circuit has been studied to allow the motors to produce sinusoidal power with reduced torque ripples. Low rotor inertia allow strong accelerations and decelerations.
