Teaching trainer for the simulation of faults in three-phase motors. Unit and motor are mounted in a painted steel structure.
Diagram in the front panel with similar distribution to the elements in the real unit.
Electrical diagram of the motor on the front panel.
The motor can be connected in star or delta connection.
Connections for the measurements.
The resistance of the windings can be measured.
6-position selector for the selection of the fault sequences.
Switch for faults activation.
Among others, the following faults can be caused and detected:
- Fault on a phase.
- Fault on the supply voltage.
- Coils with turns in short circuit (decrease of its resistance). The resistance of the windings can be measured.
- Open-ended coil.
- Short circuit between coils from different phases.
- Ground fault (motor
Faults are implemented by means a PLC and internal relays. This lets the motor can keep on working in different conditions when
certain faults are caused.
6 fuses of 2A to protect the motor.
Automatic Magnetothermal Differential switch.
Dahlander three-phase motor (0.3 to 0.5 CV), including cable and connector.
Cables and Accessories, for normal operation.
This unit is supplied with several manuals: Required Services, Assembly and Installation, Starting-up, Safety, Maintenance & Practices
Teaching trainer to simulate non-destructive faults in three-phase motors. Application of diagnostic and localisation techniques. The front panel of the unit reproduces the electrical diagram of the motor, it has connections to make all necessary measurements. It also has a power supply general switch with pilot lamps or signal lights,6 fuses of 2A to protect the motor and an automatic thermal-magnetic and differential switch for security and for checking how it gets activated when some faults take place. This unit is located between the supply electric line and a Dahlander three-phase motor that has a power between 0.3 and 0.5 CV, to enter the faults. The faults are activated with a switch and the fault sequences are selected by means a 6-position selector.
