3 Phase AC Machine With Loading Arrangement For Electrical Lab Training Description and Specifications for Lab Tenders
3 Phase AC Machine With Loading Arrangement For Electrical Lab Training Workshop.
This is a 3-phase AC machine. This is mechanically
coupled to a breakdrum to provide loading. The shaft of the machine is
coupled a drum. In turn the drum is connected to mechanical weighing pan
by means of a belt. Rotating the screws provided on either sides of the
belt can adjust the belt tension. There by it is possible to load the
shaft of the 3-phase motor with a defined tension. The difference in the
scale reading, provides the tension, the shaft is subjected to. As a
result of this the current in the windings are varied. By noting the
readings of the associated meters and the difference in the weighing pan
readings, the load characters of the motor can be evaluated.
