1.Overview
A five-phase stepper motor is a motor that realizes rotor movement by changing the direction of the electromagnetic field. Its rotation position can be controlled by changing the current. It has the advantages of precise positioning and fast response, and is widely used in various automation control systems.

2.Step angle of five-phase stepper motor
Compared with two-phase stepper motors, five-phase stepper motors have higher control accuracy. The step angle of two-phase hybrid stepper motors is usually 3.6 degrees and 1.8 degrees, while the step angle of five-phase hybrid stepper motors is further subdivided into 0.72 degrees and 0.36 degrees, which provides higher position control resolution and smoother motion control. In addition, there are high-performance five-phase stepper motors on the market, whose step angles can be smaller, such as 0.09 degrees, which further proves the advantages of five-phase stepper motors in precision motion control.

High-performance five-phase stepper motors not only provide more options in step angle, but also show their unique advantages in application fields. For example, some high-performance five-phase stepper motors can set multiple step angles through the DIP switch, which is compatible with the step angles of two-phase and five-phase hybrid stepper motors. This flexibility enables the five-phase stepper motor to adapt to more different application scenarios and needs.

3.The role of each part
1.Rotor: It is the main moving part of the five-phase stepper motor. Its magnetic field will be affected by the magnetic field of the stator coil, so that it rotates in different directions.
2.Stator: It is the static part of the five-phase stepper motor. The changes in its magnetic field and current will affect the position and speed of the rotor.

3.Control circuit: It is the core part of the five-phase stepper motor, which controls the current of the stator coil so that the rotor position and speed are accurate.
4.Power supply: Provide energy to the stator coil so that the stator magnetic field and coil current can work normally.

In general, the five-phase stepper motor occupies an important position in the field that requires precision motion control with its higher control accuracy and smaller step angle. Whether it is machine tools, medical equipment or other precision instruments, the five-phase stepper motor can provide stable and reliable performance.
