A constant speed motor has the following duty cycles

-load rising linearly from 300kW to 500kW in 4 minutes

-Uniform load of 300kW for 2 minutes

– Regenerative power returned to supply reducing linearly from 350kW to Zero in 3 minutes

– Remain idle for 3 minutes.

If the duty cycle is repeated indefinitely, determine the suitable size of a continuously rated motor for the duty cycle
