请问这个对应的是所有类型的电机还是只对应单独哪一种?

如果不是我想请问下罩机电机的对应值

以及同步电机的含义是什么?

只看馬達是否有絕緣系統，不管馬達是否有認證，依認證絕緣等級，直接對應UL982 Table 36.1所標示的耐溫值。如果絕緣系統未認證，則直接對應Class A Insulation System的耐溫值。

class A=class 105 温升限值为75K

   Thermocouple method    65
   Resistance method    85
13.    Class B insulation systems on coil windings of motorsa:
   Thermocouple method or resistance method    105
14.    a) Copper, tinned or bare strands:
   1) less than 0.015 inch diameter    125
   2) 0.015 inch diameter and larger    175
   b) Nickel, gold, or silver platings or combinations of those platings, over copper conductors    225
15.    Class E insulation systems on coil windings of motorsa:
   Thermocouple method or Resistance method    95
