A stepper motor is a kind of electric motor with an internal rotor containing permanent magnets and a set of electro-magnet coils around the rotor which are switched electronically. Good luck!. That means it can be used with all the common controllers without tripping over-current protection as it only draws 1 or 1 1/2 A at 12VDC. You'll need to be concerned with three things: piloting the motor, fastening it to the mounting surface, and coupling the shaft to your load. Stepper motors are broadly available motors commonly used for positioning. Next, try to spin the shaft of the stepper motor again. Once the motor is up to speed, pull-out torque is the maximum sustainable torque without losing steps. If this bearing is not there, the shaft is not concentric with the stepper motor housing, thus it sticks to the stepper magnets. Stepper motors have highest torque at rest or slow speeds as the speed increases torque will start to fall off. As the motor runs, it moves along the shaft at a specific rate of 1cm per 5 full rotations. One such part is Motor Pinion Gear Puller or this Motor Gear Puller.
