Application areas of stepper motors

A stepper motor is a special motor that rotates in fixed step angles. Stepper motors have the advantages of high precision, fast response speed, and easy control, so they are widely used in many fields. This article will introduce the main application areas of stepper motors.

A stepper motor is a motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement output is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. Therefore, a stepper motor is also called a pulse motor.

Stepper motors are mainly used in the field of CNC machine tool manufacturing. The reason why they are mainly used in this field is that the motor does not require A/D conversion and can directly convert digital pulse signals into angular displacement, which is exactly what CNC machine tool equipment needs, and it is also something that many other types of motors cannot achieve. Therefore, stepper motors can be said to be the most ideal actuators for CNC machine tools, and naturally they will be widely used in the manufacturing field of CNC machine tools.

Stepper motors are mainly used in the field of CNC machine tool manufacturing, but it does not mean that they are only used in this field, because in terms of their uses, in addition to this field, they can also be used in many other machines, such as motors in automatic feeders and general floppy disk drive motors. In addition, they can also be used in printers and plotters.

Stepper motors have the characteristics of fast start and stop and positioning. In the field of digital control, stepper motors are often used as actuators for position control. When the stepper motor is running quickly, the drive circuit is required to provide the drive current to the stepper motor winding as close as possible to the value required by its technical indicators to generate sufficient torque. The maximum temperature allowed on the surface of the stepper motor. Stepper motors are used with drivers. Many drivers support subdivision functions, that is, to achieve very small step angles and more precise control. The torque of the stepper motor will decrease with the increase of speed. The accuracy of a general stepper motor is 3-5% of the step angle, and it is not accumulated. The stepper motor can operate normally at low speed, but it cannot be started if it is higher than a certain speed, and it is accompanied by a howling sound.

It is widely used in ATM machines, inkjet printers, engraving machines, photo machines, spraying equipment, medical instruments and equipment, computer peripherals and mass storage devices, precision instruments, industrial control systems, office automation, robots and other fields. It is particularly suitable for applications that require smooth operation, low noise, fast response, long service life and high output torque.
