Armature chokes, typical temperature during operation of armature chokes
Question:
Which typical surface temperatures are normal / uncritical for armature chokes?
Answer:
The isolation materials used for Lenze armature chokes (order designation: ELA1-...) correspond to isolation class F, this means die limit of temperature rise is 100 K or the limit of temperature is 155 °C respectively. A surface temperature of 85 °C is typical, only temperatures of more than 100 °C lead to a restricted life time.
