coal mill gearbox three stage speeds

Understanding Motor and Gearbox Design : 10 Steps (with

For example, combining a Fisher Price and CIM motor would require an extra 3:1 gear reduction for the Fisher Price motor because its output speed is approximately 3 times faster than a CIM’s. If the output speeds are not matched, it will cause added resistance in the gearbox and negate any benefits of having multiple motors.
