This article will introduce you to the basics of stepper motors, including their operating principle, construction, control methods, uses, types and their advantages and disadvantages. 1. stepper motor basics Stepper motor is a kind of motor that rotates the shaft by stepping (i.e. moving at a fixed angle). Its internal structure makes it possible to know the exact angular position of the shaft without a sensor, by simply calculating the number of steps. This feature makes it suitable for a wide range of applications. 2. stepper motor principle of operation Like all motors, stepper motors include a fixed part (stator) and a movable part (rotor). The stator has a gear-like protrusion around which a coil is wound, while the rotor is a permanent magnet or variable reluctance core. We will cover the different rotor configurations in more depth later. Figure 1 shows a cross-section of a motor with a variable reluctance core rotor.Translated with DeepL.com (free version)
The most basic motor is the “DC motor (brush motor)”. By placing a coil in a magnetic field and passing a flowing current through it, the coil will be repelled by the magnetic poles on one side and attracted by the other side at the same time, and will keep rotating under this action. During the rot
The screw stepper motor uses a screw and nut to engage, and takes a certain method to prevent the screw nut from rotating relative, so that the screw moves axially. Advantages include high precision and repeatability, the ability to hold position without power, and excellent torque at low speeds, making them ideal for applications like 3D printers and CNC machines. Additionally, they offer simple control systems, making them user-friendly for various automation tasks.
Advantages Of Stepper Motors Being Widely Used Stepper motors are now well known and widely used by most people, which is of course due to their own advantages and performance. In particular, the step value of the motor is not affected by various disturbing factors. Such as the size of the voltage, the value of the current, the waveform, the change of temperature and so on.
