FR-4环氧板绝缘的温度等级一般分为A级、E级、B级、F级、H级、C级、N级、R级。一般电机的绝缘等级较多采用E级和B级绝缘。机的热分级是指其所用绝缘材料的耐热等级，分A、E、B、F、H、C、N、R级。允许温升是指电动机的温度与周围环境温度相比升高的限度。 FR-4环氧板温度等级：绝缘的温度等级A级E级B级F级H级C级N级R级； 最高允许温度（℃）105 120 130 155 180 200 220 240； 绕组温升限值（K）60 75 80 105 125 135 150 170； 性能参考温度（℃）80 95 100 120 145 155 170 190。 FR-4环氧板加工在发电机等电气设备中，绝缘材料是最为薄弱的环节。绝缘材料尤其容易受到高温的影响而加速老化并损坏。不同的绝缘材料耐热性能有区别，采用不同绝缘材料的电气设备其耐受高温的能力就有不同。因此一般的电气设备都规定其工作的最高温度。
