Why are the field loss detectors necessary in the large dc motors?
Field loss detectors are essential in large DC motors because they monitor the integrity of the field winding, ensuring that the motor operates safely and efficiently. If the field winding fails or experiences a loss of excitation, the motor can run at dangerously high speeds, leading to mechanical failure or damage. By detecting field loss promptly, these devices can trigger protective measures, such as shutting down the motor or reducing its load, thereby preventing accidents and extending the motor's lifespan. Overall, field loss detectors enhance the reliability and safety of large DC motor operations.
What are the possible losses for a dc generator?
Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
When excitation failure?
Excitation failure occurs when a generator or synchronous machine fails to maintain its magnetic field, leading to a loss of voltage and stability. This can result from issues such as a malfunctioning excitation system, loss of a power supply to the exciter, or mechanical failure. The consequences can include decreased system performance, potential damage to equipment, and disruptions in power supply. Proper monitoring and maintenance of the excitation system are crucial to prevent such failures.
What are the functions of Total productive maintenance?

What is magnetic loss in the stator called?
Magnetic loss in the stator is commonly referred to as "core loss" or "iron loss." This loss occurs due to the alternating magnetic field in the stator, which leads to energy dissipation primarily through hysteresis and eddy currents in the magnetic core material. Hysteresis loss is related to the magnetic properties of the material, while eddy current loss is caused by circulating currents induced in the core. Together, these losses reduce the overall efficiency of electromagnetic devices like motors and transformers.
