The unit is designed for studying the operation of the electric motor. It has an electric motor fault simulator.
The basic types of faults in three-phase asynchronous motors which can be studied with use of the simulator:
- simulation of the U-phase short circuit to ground;
- simulation of the V-phase short circuit to ground;
- simulation of the W-phase short circuit to ground;
- simulation of the U-phase winding interturn fault;
- simulation of the V-phase winding interturn fault;
- simulation of the W-phase winding interturn fault;
- simulation of the U-phase winding breakage;
- simulation of the V-phase winding breakage;
- simulation of the W-phase winding breakage;
- simulation of the U and V-phases interphase fault;
- simulation of the U and W-phases interphase fault;
- simulation of the V and W-phases interphase fault;
- simulation of the wrong winding breakage.
Each of the faults is set with a separate tumbler switch. It allows combining several faults simultaneously.
The panel allows to conduct the following experiments:
- Simulation of a short circuit phase on the case.
- Simulation of inter-turn phase winding.
- Simulation of phase winding breakage.
- Simulation of interphase closure of phase windings.
- Incorrect winding connection.
The complete set contains:
- removable module of asynchronous electric motor, pc. – 1;
- fault regulator, pc. – 1.
