VFD control panels UNIDRIVE-T series
The UNIDRIVE-T series control panels have been specifically designed for the feeding and control of the motors for the rotation of the TBM Cutterhead.
Being very high the powers involved, combined with the dimensions that must be as small as possible, given the purpose of application, there are specific problems inherent in heat dissipation: to solve these problems, in addition to the use of special liquid-cooled VFD units, the UNIDRIVE-T series switchboards are built to house a circulation system for cooling water which, in addition to the heat exchangers which regulate the internal temperature of the switchboard, also reaches the cooling system of each individual frequency converter.
