DC and AC electric motors
MCA and ESA tests
Engine Circuit Analysis (MCA™) is a de-energized test that assesses the health of the engine. It can be performed from the Engine Control Center (ECC) or directly on the engine and examines the entire electrical system, including connections and wiring.
Electrical Signature Analysis (ESA) is an energized test method that captures voltage and current waveforms while the motor is running. This approach provides valuable information about AC and DC induction motors, generators, synchronous motors, and more.
DC and AC electric motors
MCA (Motor Circuit Analysis) Testing.
Contact resistance (resistive)
Measures the resistance of electrical contact connections to ensure they have low resistance, which guarantees an efficient connection and reduces power loss or overheating.
Insulation resistance (resistance)
Evaluates the insulation capacity of the motor or electrical system to prevent current leaks, ensuring safety and proper operation.
Phase angle
It measures the time difference between voltage and current in a circuit, a crucial parameter for evaluating motor efficiency and detecting possible imbalances or electrical problems.
Current/Frequency (I/F)
It verifies the relationship between current and frequency in the operation of the motor, helping to identify problems such as imbalances, overloads or variations in the electrical supply.
ESA (Electrical Signature Analysis) tests.
Voltage and current imbalance
Evaluates whether there are differences between voltage or current phases in the motor, which could indicate faults such as poor connections, charging problems or anomalies in the power supply.
Detects so many mechanical and electrical problems
Analysis that can identify both electrical faults (such as short circuits or damaged insulation) and mechanical faults (misalignment, bearing wear, etc.), ensuring a comprehensive diagnosis of the motor.
Vibration analysis for bearings and eccentricities
Evaluation that measures motor vibrations to detect bearing problems, rotor imbalances or eccentricities that may cause mechanical failures.
Rotor shaft test
Checks the integrity of the rotor, evaluating its alignment and condition to detect defects such as deformations, cracks or wear, which can affect the efficiency of the motor.
