Balancer for Axial Fans With External Rotor Motor Balancing Machines for Auto Fan Blower Balance Machine for Car Fan Motor Balancer for centrifugal blower with motor Balancer for Axial fan with motor Balancer for blower fan motor ...... FAB-5 machine which is designed by designed and developed on our own is a special balancing machine for motor assemble with impeller. The balanced test equipment which shows rotate speed, unbalance value, phase position in English and figures is adopted with micro computer test system. The unbalance values are directly by the unit of gram. Electromechanical transducer is adopted with piezoelectric sensors which are characteristic with easy to operate, high accuracy. Its main technical parameters are in the following. Its main technical parameters are in the following. Rotor data/ Machine type FAB-5 Max.weight of workpiece on roller carriage( kg) 5( suitable for 0.5~ 5) Max.diameter of workpiece over the machine bed( mm) 400 Balancing speed( rpm) self-driven Minimun achieveable residual unbalance( MARU) ( g.mm/ kg) d1 Unbalance reduction ratio( URR) ( % ) e90 Power supply 220V 50Hz We also accept order with special specification.
