Read MoreThe motor designer (or vendor) will convert the specified rated mill speed into the speed of the motor, ωrated as Hz, which for a Gearless Mill Drive is simply ϕRPM ÷ 60. For a gear driven mill, the motor speed is a function of the mill speed ϕRPM, and the gear ratio of the mill bull gear and the drive pinion.
