The integrated stepper motor is a kind of motor commonly used in automatic control system, which has the advantages of precise control, accurate positioning, high efficiency and energy saving, so it is widely used in industrial automation, medical equipment, smart home and other fields. This paper will introduce the basic working principle, structure characteristics and application scenarios of the integrated stepper motor.
1. Basic working principle

The working principle of the integrated stepper motor is similar to that of the traditional stepper motor, which realizes rotation by controlling the magnetic field of the motor, but it uses a fully digital control mode, that is, the control circuit and the motor body are integrated together, and the motor movement is controlled by digital signals.
Specifically, the controller of the integrated stepper motor sends a series of pulse signals to the motor, and the frequency and number of these signals determine the speed and rotation direction of the motor. Each time a pulse signal is received, the motor will rotate forward at a certain Angle, which is usually fixed, called the step Angle. By constantly sending pulse signals, the motor can be controlled to rotate at a certain speed, direction and Angle.

2. Structural characteristics
The structure of the integrated stepper motor has the following characteristics compared with the traditional stepper motor:
Integrated design: The control circuit and the motor body are integrated together, occupying small space and convenient installation and maintenance.
High-precision sensor: The integrated stepper motor uses high-precision sensors to detect the position and speed of the motor in real time to ensure the accuracy and stability of the motor.
High efficiency and energy saving: The integrated stepper motor adopts digital control mode, which can effectively save energy and improve the efficiency and life of the motor.
Self-protection function: integrated stepper motor built-in overcurrent protection, overheating protection and other safety protection functions, can effectively avoid motor damage due to external factors.

3. Application scenarios
Integrated stepper motors are widely used in the following fields:
Industrial automation: The integrated stepper motor can be used in automatic control systems, industrial machinery and other fields, with high precision, high reliability and other characteristics.
Medical equipment: The integrated stepper motor can be used for the control and positioning of medical equipment, such as CT, MRI and other medical equipment.
Smart home: The integrated stepper motor can be used for smart curtains, smart door locks, etc.
