The Class H series of three-phase asynchronous motors are designed with a Totally Enclosed Fan Cooled (TEFC) construction and are available in both cast iron and aluminium housing. These motors are an enhancement over our standard induction motors and share the same technical data. They are specifically designed to meet the High Temperature Resistance requirements and can endure an ambient temperature of up to 85 °C and an internal winding temperature of up to 300 °C for up to 2 hours. This is achieved through the use of higher temperature safety margins and enhancements made to our internal winding, among other things.
