DC tachogenerator VARIMOT Acionamentos

The BR11-Series tachogenerators are manufactured with 60 volts rated voltage at 1000 RPM, with 20 or 40 volts optional at 1000 RPM and maximum speeds up to 5000 RPM. They are comprised of two different parts, rotor and stator with total length reduced.
It has hollow shaft and embodies an original fixing device, allowing direct mounting to the extension of the shaft end, forming a rigid coupling. In addition to eliminating the roller and couplings, reducing the length, it eliminates every possibility of vibration torsion between the motor shaft and the rotor, producing a better quality signal, especially in the acceleration and deceleration stages.
