Unbalance Vibrator Motors



Questionnaire for Unbalanced Vibrator Motor

ELEKTROMAG-AEG Vibrator Motors are robust, reliable, highly loadable, quite-running and require no maintenance. Their essential characteristics are :

  • Generously dimensioned cylindrical roller bearing, self lubricating maintenance-free, long life expectancy;
  • Embedded in high-quality impregnating resin vibration-proof winding, insensitivity to damp and dust;
  • Dust-tight and water-tight through a sealing covering with special circular rubber washer;
  • Robust terminal board, cast in synthetic resin;
  • Reliable starting by means of a high-powered starting torque;
  • Quality-tested components, each motor tested under load;
  • Permanent and well legible setting marking of the unbalance weights;
  • One or two solid lifting lugs;
  • Vibration-proof joining through the considerable tensility of the mounting screws;
  • Absolutely secure centrifugal mounting; only the inner centrifugal weights are steplessly adjustable, the outer ones cannot even be dislodged through an unintentional loosening, due to the provision of a retaining ring;
  • Highly stressed casting of ductile cast iron;
  • Universal mounting facilities through an optimum choice and interspacings in the base mounting;

POWER CONNECTION

Vibration motors are connected to a three-phase system with protective conductor. Connection can be effected as per fig. 3 in the simplest manner by means of a common contactor, which must be interlocked by means of auxiliary contacts. With two motors, protection circuit-breakers are required.

On the other hand, with the latter connection, considerable oscillatory occur, to a greater or lesser extent, on the disconnection of the equipment, due to the fact that resonant frequencies of the support springs will have a comparatively slow run through, especially at a time when the trough is empty and the bulk material is absent. For this reason, a connection of the motors via a break unit, Fig. 4 with which the motors can be brought to a standstill through d.c. braking in a period of one to two seconds, is recommendable.

 

 

EXAMPLES OF APPLICATIONS
As drive for Vibrating conveyors, Conveyor throughs and tubes, 
Conveyor sections, Vibrating screens, Bar  grid screens, Helical conveyors.
As vibrators for Silos, Bins, Deflection, grids, Filters, Filling plant, Chutes, Gravity pipes.
