    Torque & Motor H.P Required for Drum Rotation of 3T Weight

    Dear cosyindia: This is a problem that I have encountered recently while designing a coater drum for the food industry. I am assuming the following: -that the water remains quasi-stationary at the bottom of the drum and that it is not lifted by some sort of baffle to a higher point in the...

    Undergrad Torque required to reduce the speed of a rotor?

    Dear Mark You are so close to the answer. By this I mean that you have all the physical properties required to calculate the Torque. The key is to remember that any rotational problem is analogues to linear problems and you can utilize Newton's second law to calculate the torque. Firstly I...

    Does torque reduce/increase through gears?

    Dear PaulMa The key is to remember that power is constant throughout the drive train. Keeping this in mind together with the formula: P = T * omega shows you that when the power remains constant and the speed decreases, as is the case with the rotor of the wind turbine, then torque will...
