I am trying to do a project on electrical engineering which involves design of electrical circuitry for a soot blower arrangement.i am having problems in designing a motor( 3phase induction motor). i know how to calculate the rotor parameters,losses, efficiency,etc. i am told that i have to find the load and load torque on the motor. how do i do that and how i proceed from there?.i would appreciate if anyone can help me in this.

To produce that power, you will need to factor in the efficiency of an electric motor, which is typically 7580%. The torque of the motor will depend on how it is connected to the load. If it is directly connected (same speed as fan) the torque is related to the fan speed: [tex]Power = \tau\omega = 2\pi\tau f [/tex] where f is the speed in revolutions per unit time AM

there is no fan invovled here( sorry i shud have mentioned)the cleansing media is steam and directed directly from a steam manifold.how do i go ahead?
