Vertical Spin bench for E-rotors type ESV25-AR

The balancing of electric rotors also includes accelerating them to their later operating speed in the vehicle. This run-up to operating speed - also known as spinning - often leads to a shift in the mass of the laminated cores within the rotor, which in turn leads to a changed unbalance. With regard to the relatively low unbalance tolerances of the E-rotors, a centrifugal process is essential, so that this is part of the balancing of the rotors. The Hofmann spin benches are available in a horizontal and vertical orientation. With the addition of the active balancing system AB9000 developed by Hofmann, it is even possible to spin the e-rotor before the actual balancing process, which in turn means that a complete work step, namely the pre-balancing of the rotors, is eliminated. Loading can be done manually or automatically by a robot.
