Development Trend Of Linear Stepping Motor

The development of linear stepper motors is closely related to the computer industry. Since linear stepping motors have replaced small DC motors in computer peripherals, the performance of their equipment has improved and the development of linear stepping motors has been promoted.

On the other hand, the development of microcomputers and digital control technologies will apply linear stepper motors as executive parts of numerical control systems to other fields, such as electrical machining machine tools, small power machining machine tools, measuring instruments, optical and medical instruments Packaging machinery, etc. So where should the trend of linear stepper motors go in the future?

In the process of maturity of any product, the specifications and varieties are gradually unified and simplified. The development of linear stepper motors at this stage has come down to three types of single-stage reluctance, hybrid and claw-pole permanent magnets. The claw pole motor is cheap and the performance index is not high. The hybrid and reluctance type are mainly used as high-resolution motors. Because the hybrid linear stepper motor has low control power and good running stability, it gradually takes the lead.

The most typical products are two-phase 8-pole 50-tooth motors with a step angle of 1.8 ° / 0.9 ° (full step / half-step); and two-phase and five-phase 5-phase 10-pole 50-tooth and some rotor 100-tooth Stepping motors and five-phase motors are mainly used for occasions with high running performance.
