System for the study of failures on a asynchronous squirrel cage motor 1500W + brake.
Diagnosis panel for student + Panel for teacher with controls.
- Simulating common failures encountered with a cage induction motor with brake: damage winding, cut, shorted to ground
- Diagnosis by performing measurements and safety tests
Practical works
- Cut Winding
- Winding in short circuit
- Winding to ground
- Damaged winding
- Cut brake control system
This complete kit on casters, comprising two back-to-back units and an asynchronous squirrel cage
motor and a parking brake, can be used to simulate the faults which occur most frequently.
The principle and the instructions have been devised by teachers who want to propose a method for
diagnosing faults.
PRINCIPLE
Faults are recreated when the teacher rotates a single switch. Students can take measurements or
perform tests in complete safety, regardless of the fault type. Faults can be looked for inside the student
unit and in the motor terminal. The unit is isolated from the mains by means of an insulation transformer.
In addition, a TT earthing system is recreated on the secondary for safety reasons.
Therefore, even isolation faults are detected by a 30mA differential mechanism. All safety measures
are implemented in order to protect individuals and equipment. (See the faults in the description of
the teacher unit)
