Totally Enclosed Fan Cooled (TEFC) High Voltage Cage Induction Motors

Flowpak motors comply with the requirements of IEC 34-1, the relevant parts of BS4999 and BS5000, IS:325 & other relevant Indian standards. They are designed for continuous duty corresponding to Duty Type S1 of IEC 34-1 and BS4999, part 101 section 3, with a temperature rise by resistance not exceeding 80K in a maximum ambient temperature of 40°C. The standard rated outputs are taken from the R40 series of preferred numbers in accordance with the requirements of clause 7 of BS4999 Part 101 and Part 1 of IEC 34-1. For enquiries with intermediate ratings the next highest preferred rating will be offered and performance data will be quoted accordingly. This maximises the cost and lead time benefits available from the range design.
