D.c. permanent magnet servomotors BR series These d.c. servomotors include ferrite magnets, plus rotors with many slots and many commutator segments to guarantee absolute smooth rotation even at speed lower than 1 RPM. TENV execution, IP 54 protections. The overtemperature is in F class, although almost all materials employed have H class capability. The standard version includes the hollow shaft tachogenerator BR 11/2,20V/1000 RPM. As option a 24Vd.c. stopping brake can be incorporated in the motor. The servomotors are available with many windings at different nominal speeds and with armature voltage from 60 to 170 Volt to optimize the torque constant.
