Frecuentemente escuchamos decir a nuestros miembros, que uno de sus clientes le ha informado que un motor que había sido reparado, ahora se calienta. Nosotros siempre les preguntamos ¿Qué tan caliente? y por lo general responden “Bueno, no puedo mantener mi mano sobre él”.
Vamos a pensar un minuto en esta respuesta. La mano del ser humano típico, puede soportar una temperatura entre 60-65°C (140 -150°F), dependiendo de las callosidades, el dolor que pueda tolerar, cuantas personas estén observando, etc. Recuerden este número, mientras discutimos las temperaturas típicas de funcionamiento de un motor.
La norma NEMA MG1-2009 12.43 (ver Figura 1), define el aumento de temperatura para los motores a una temperatura ambiente máxima de 40 °C.
