      Description

      The attraction and holding of the magnetic pieces are obtained by feeding the coil inside the solenoid. When the power supply stops, the solenoid looses the piece. When working with hanged loads, security norms must be respected.

      The data shown in the chart are the Magnetic Force (Fm) values depending on the air gap, measured in the following conditions:

      • Direct current supply.
      • Flat piece (3 µm rugosity) in AºSt37 and thickness as shown.
      • Room temperature 35ºC.
      • Coil working on its regime temperature.

      The dimensions of the pieces used in the test are similar or bigger than the attraction face of the different holding electromagnets. At different conditions, the magnetic force (Fm) may decrease.

      The value of the magnetic remanence after the power supply stops is 5% of the holding force.

      When lifting or handling heavy loads a minimum security margin of 3 must be respected, the weight of the load cannot exceed 33% of the magnetic force.
