Best Stepper Motor for 3D Printer – Know Everything Before Buying


The right option for you depends on the torque you require. This is because these motors are divided based on their torque ratings. There are basically 3 types of stepper motors: pancake, standard, and high torque. Now, unless you know the torque requirements of your particular 3D printer, you will not be able to make a choice. Also, picking the wrong one will cost you dearly because it won’t work at all. Here’s a brief about each to make things easy for you:

  1. Pancake stepper motor: This is ideal for lightweight or low torque applications. It is small in size and simple with 20-25N*cm torque rating. It is best used for direct-drive extruders with the biggest advantage being its price and compact design.
  2. Standard stepper motor: As the name implies, this is the standard option with 40-45N*cm torque rating. It is the most popular option and works with a majority of 3D printers. It is larger than a pancake stepper motor and has a wide range of applications. 
  3. High torque stepper motor: These are the largest and most powerful with 50-56N*cm torque rating. They can only be used in a fixed position because they are large. They work best for CNC work and not much with 3D printing. So, you can essentially ignore these. 

Once you determine the type of motor you want based on the torque, you can choose the best based on rated current, inductance, resistance, rated voltage, etc.
