Advantages of linear stepper motors:

1. Linear stepper motors comprehensively replace DC motors for speed regulation, variable frequency converters for speed regulation, and asynchronous motors+reducers.

2. It have all the advantages of traditional DC motors, while eliminating carbon brush and slip ring structures; It has the feature of small size, light weight, and high output power.

3. It can operate at low speed and high power, eliminating the need for the gearbox to directly drive large loads.

4. It has good torque characteristics, good torque performance at medium and low speeds, high starting torque, and low starting current.

5. Stepless speed regulation, wide speed range, strong overload capacity; Optional trapezoidal wave magnetic field motor and forward rotating wave magnetic field motor as needed.

6. High reliability, good stability, wide adaptability, and simple maintenance.

7. Anti impact vibration, low noise, low vibration, smooth operation, and long service life.

8. No radio interference, no spark generation, especially suitable for explosive locations, with explosion-proof type.

In the field of aerospace, there is a high demand for the accuracy of mechanical devices. Linear stepper motors can meet the application requirements of the aviation industry with their own advantages. Linear stepper motor is a driving device that can convert current pulse signals into micro step linear motion. In situations where precise linear motion is required, linear stepper motors are widely used for their high-speed positioning, high reliability, and high-density digital linear motion servo systems. It can replace an indirect mechanical device that achieves linear motion by rotating a stepper motor through a set of intermediate conversion devices.

The structure of a linear stepper motor is relatively simple, without an intermediate conversion structure. The moving part is light in weight, having small inertia, without drift phenomenon, and having no accumulated positioning error. Linear stepper motor is an ideal high-precision instrument with high positioning, which can be developed, applied, and widely promoted. The hybrid linear stepper motor is a simple improvement. It has been widely used in computer equipment applications, CNC machine tools, automatic plotters, robot development, transmission equipment testing and control, and other fields. Especially in recent years, the rapid development of microelectronic devices and interface technology has greatly reduced the cost of automation, intelligence, and highly integrated linear stepper motors, and has great development potential and broad promotion prospects in the aerospace field.
