A step motor is a type of electric motor that uses a series of electrical pulses to move the rotor. The rotating rotor causes a linear actuator, which produces motion in one direction. The pancake stepper motor is a type of step motor that has the capability to rotate continuously in both directions without any need for periodic rotary encoder. It is also known as the "pancake" stepper because it resembles a pancake, with its flat shape and circular cross-section. This article discusses how this type of step motors work and their applications in industrial machinery such as 3D printers, CNC machines, and robotics. What Makes the Pancake Stepping Motor Different From Others? The pancake stepping motor is a type of electric generator that uses an electromagnet to produce electricity. It is also known as the pancake motor because it looks like a pancake when it is folded in half. It has been around since the 1970s, but it saw a surge in popularity after the Fuk
