For motor-only applications, the slower the electric motor speed, the bigger the motor must be. Large motors could be expensive and might not match within the allowable envelope space of a credit card applicatoin. Utilizing a gearbox with a smaller motor allows the unit to use at lower speeds.

To be able to understand the need for using a gearbox to diminish motor speed, think about this scenario. You possess a pastry conveyor that adds cherry filling as the pastries go by. Because this can be a reasonably light load, you’ll not need the conveyor speed gearbox operating at 5000 rpm. If it had been, there would be pastries and cherry filling just about everywhere!
