Electric Centrifugal fan motors are an important component of many industrial and commercial applications, ranging from HVAC systems to manufacturing processes. To ensure the durability and reliability of these Centrifugal fan motors, it is essential to protect them from electrical faults, in particular by choosing the appropriate insulation class.

The international standard for motor insulation classes is essential to ensure the safety, efficiency, and reliability of Centrifugal fan motors. The maximum operating temperature depends on the design, size and application of the Centrifugal fan motor. The maximum operating hot spot temperature is achieved by adding the nominal ambient temperature of the machine (often 40 °C), the temperature rise, and a 10°C hotspot allowance. Electric machines are usually designed with an average temperature below the rated hot spot temperature to ensure the required service life.
