A stepper motor is a special type of motor that rotates in fixed step angles. Stepper motors offer advantages such as high precision, fast response, and easy control, and are therefore widely used in many fields. This article will introduce the main application areas of stepper motors.
A stepper motor is a type of electric motor that converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational 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. This is exactly what CNC machine tool equipment needs and what many other types of motors cannot achieve. Therefore, stepper motors can be said to be the most ideal actuator for CNC machine tools, and naturally they are widely used in the field of CNC machine tool manufacturing.
Stepper motors are primarily used in CNC machine tool manufacturing, but this doesn't mean they're only used in this field. Besides CNC, they can be used in many other machines, such as motors in automatic feeders and general-purpose floppy disk drives. Furthermore, they can be used in printers and plotters.
Stepper motors are characterized by rapid start/stop and positioning, and are frequently used as position control actuators in digital control fields. During rapid operation, the drive circuit must provide the stepper motor windings with a drive current as close as possible to its technical specifications to generate sufficient torque. The maximum permissible temperature for a stepper motor's exterior is also important. Stepper motors are used in conjunction with drivers; many drivers support microstepping, enabling very small step angles for more precise control. The torque of a stepper motor decreases as its speed increases. Generally, the accuracy of a stepper motor is 3-5% of the step angle, and this accuracy does not accumulate. Stepper motors operate normally at low speeds, but above a certain speed, they fail to start and produce a whistling sound.
It is widely used in ATMs, inkjet printers, engraving machines, photo printers, 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 especially suitable for applications that require stable operation, low noise, fast response, long service life and high output torque.
