GEARBOX&SPEED
For motor-only applications, the slower the electric motor speed, the bigger the motor needs to be. Large motors could be expensive and may not fit within the allowable envelope space of an application. Using a gearbox with a smaller motor allows the unit
to operate at lower speeds.
In order to understand the importance of using a gearbox to decrease motor speed, consider this situation. You have a pastry conveyor that provides cherry speed gearbox filling as the pastries go by. Because this is usually a fairly light load, you would not need the conveyor working at 5000 rpm. If it had been, there will be pastries and cherry filling all over the place!
