Abstract
CIRCUITO AVISADOR DE SOBRECARGAS EN MOTORES ELECTRICOS. EN UNA FASE (3) SE INTERCALA UNA RESISTENCIA (R) CUYA TENSION SIRVE DE REFENRENCIA DE INTERSIDAD Y AMPLIFICADA (VI) SE INTRODUCE EN UN MULTIPLICADOR (MU) Y EN UN SUMADOR (SV), A TRAVES DE UN POTENCIOMETRO (CO) PARA TENER EN CUENTA LAS PERDIDAS JOULE, SIENDO LAS OTRAS ENTRADAS DEL SUMADOR (SV) REFERENCIA DE TENSION, Y SU SALIDA (VU) ENTRA AL MULTIPLICADOR (MV), DONDE SE OBTIENE UNA SEÑAL DE POTENCIA A LA QUE, EN UN SUMADOR (SI), SE LE RESTA UNA SEÑAL (KU) DE PERDIDAS EN EL HIERRO Y OTRA DE UN POTENCIOMETRO (P2) DE PERDIDAS EN VACIO, OBTENIENDOSE UNA SEÑAL (P), A LA QUE SE LE RESTA EL AUMENTO (P) DE PERDIDAS DE JOULE CON LA TEMPERATURA. LA SEÑAL TOTAL (S) SE COMPARA CON UNA TENSION DE REFERECIA (UR), QUE SI SE SOBREPASA, SE DISPARA UN RELE (RE1) INDICADOR DE SOBRECARGA. PARA AJUSTAR LAS PERDIDAS EN VACIO SE TOMA LA TENSION DE REFERENCIA NULA CERRANDO EL INTERRUPTOR (K).
