Hola comunidad, hoy les comparto un mantenimiento preventivo realizado a motor trifásico de 5 HP. Como se puede ver en la imagen, se desarmo el motor por completo y se cambiaron ambos rodamientos ya que estos se encontraban con desgastes y esto trae como consecuencia que el rotor tenga dificultad al girar y aumente la corriente de consumo. Seguidamente se realizó un lavado con dieléctrico para quitar la grasa, polvo y toda sustancia que ocasione resistencia al paso de corriente que circula por la bobina. Es importante que luego de estos pasos se haga la prueba de aislamiento a las bobinas del motor para verificar que estas tengas el nivel de aislamiento requerido y así estar seguro que el motor no tenga fuga de corriente con la carcasa, esto se realiza con un instrumento de medición eléctrica llamado (MEGER) y el nivel de aislamiento que debe tener una maquina rotativa es de 5000 MEGA OHMS. Por último, se realiza nuevamente el armado del motor y se coloca en funcionamiento para tomar las mediciones de corrientes y que estas estén de acuerdo con los datos de placa del motor, esto se realiza mediante una pinza amperimetrica. Espero que este aporte les sea de ayuda.
Hello community, today I share with you a preventive maintenance performed on a 5 HP three-phase motor. As you can see in the picture, the motor was completely disassembled and both bearings were changed as these were with wear and tear and this causes the rotor to have difficulty rotating and increase the current consumption. Next, a dielectric wash was performed to remove grease, dust and any substance that causes resistance to the current flowing through the coil. After these steps, it is important to test the insulation of the motor coils to verify that they have the required insulation level and thus be sure that the motor has no current leakage with the casing, this is done with an electrical measuring instrument called (MEGER) and the insulation level that a rotating machine must have is 5000 MEGA OHMS. Finally, the motor is reassembled and placed in operation to take measurements of currents and that these are in accordance with the data plate of the motor, this is done using a clamp amperimetric. I hope this contribution will be of help.
Nice work i was hoping to see more photos of the fix, hope it continues to work.
gracias amigo, sigue en funcionamiento y disculpa por la fotos que faltaron, pasa que se me borraron y solo me quedo esa. Estamos a la orden por cualquier duda
Bummer about the other photos. Nice work thnaks for sharing.
