All About CNC Stepper Motors

CNC stepper motors are designed to be used on mid-sized and small CNC mills and milling machines, lathes, engravers, cutters, plasma cutters, vinyl sign cutters, foam cutters, and many more.

stepper motor control system are used in other things besides CNC machines, like robots. These motors offer advanced torque curves as well as low inductance. These motors, because of advanced torque curves and the low inductance that they offer, are the best choice for higher-speed rapids and close lead screw pitches.

CNC stepper motors come in basically two different forms: the unipolar motor and the bipolar motor. The bipolar series of motors use the full coil, which in turn gives great torque at low speeds; however, the higher the inductance quality that is offered with the CNC stepper motors, the more quickly torque drops off.

Other bipolar motors are offered, for example, the bipolar parallel motors which also use the full coil.

Unipolar and bipolar half coil stepper motors do not give great torque at low speeds because fewer turns are being used; however, because of the low inductance quality that is offered with the CNC stepper motors, the torque is held out at higher speeds.

As with any other CNC motor, the motor quality, reliability and compatibility will all depend upon the brand that is purchased. Different manufacturers offer different setups, different options, and different configurations between their CNC machines and the CNC stepper motors that are designed to work with each other.

You will be better off if you purchase a CNC stepper motor that is of the same brand and that will work with the CNC machine that you currently have or that you are looking at buying.
