What are the Key Functions of a Stepper Motor?

Under the hood of every 3D printer out there, you’ll find a stepper motor.

The proper definition of a stepper motor is a brushless DC electric motor that divides a full rotation into an equal number of steps. The position of the motor can be ordered to move and hold at certain steps and used at your desired torque and speed.

In simpler terms, stepper motor is what the motherboard uses to communicate to the motors of your 3D printer to make it move around the various axes. It gives the precision, speed and positioning of how things move so it’s a very vital component of a printer.

The reason stepper motors are used in 3D printers is because of their wide range of benefits such as low cost, high torque, simplicity, low maintenance while being highly reliable, and works in just about any environment.

Also on the technical side of things, they are very reliable because there are no contact brushes in the motor, meaning the life of the motor depends solely on the longevity of the bearing.

Stepper motors are also used in medical instruments, engraving machines, textile equipment, packaging machines, CNC machines, robotics and much more.
