Rod S****I purchased the 3-pack of the smaller steppers for my current ender 3 pro project. For my applications, they work perfectly. It's a great deal for quality motors, and I'm going to purchase another 10 packs.
Sam N***These are great motors and they are very strong. They are operating quietly, and also need them to release their hold every time a move is complete.
Jim S**Please develop more low noise gearbox and with better prices, so we can sell your products to more clients and gain larger markets. Thank you.

Another reason to use a gearbox with a stepper motor is to increase the torque available to drive the load. When the load is driven by a motor-gearbox combination, the gearbox multiplies the torque from the motor by an amount proportional to the gear ratio and the efficiency of the gearbox.
Since stepper motors and other control motors are designed to allow accurate positioning, the gearheads used for these motors must provide the same level of accuracy.A gearbox—otherwise known as a gear reducer or speed reducer—is a set of gears that can be added to a motor to drastically decrease speed and/or increase torque.Each gearbox type works in unison with a motor to achieve the desired speed-torque output.
