	How is the efficiency of motors kept same between 60% to 100% load & as such manufacturers show flat efficiency curve for this range ?

	Simple. Match the motor to the load and keep the speed and torque that the motor delivers inside that band. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Its size and performance characteristics can be obtained from manufacturers' tables. Simply select a motor that will do the job. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	I want to understand the design parameters taken care of during manufacturing for obtaining flat efficiency curve between 60% to 100% load.

	Are you trying to copy a motor for business/financial reasons? __________________ "What others say about you reveals more about them, than it does you." Anon.
