Technical specifications

The BR series servomotors are designed to offer the highest dynamic performance and are used in
applications such as CNC lathes, servopumps, metalworking machines, woodworking machines,
plastic and rubber processing machines.

The use of Neodymium Iron Boron magnets with a high energy product makes it possible to obtain motors with high specific power capable of withstanding large overloads without the risk of demagnetisation.

The magnetic circuit has been designed to allow the motors to produce a sinusoidal F.e.m. with reduced torque ripple.

The low rotor inertias guarantee the possibility of high acceleration and deceleration.
