Stepper motor & # 8203; Introduction of stepper motor stepper motor, the typical motion control motor, is the performance of the components in informatization, automation control system. Principle of stepper motor is the electrical pulse signal into angular displacement or linear displacement of open loop control elements, on the basis of the pulse signal, step motor according to the set direction rolling fixed point (Step torque Angle), through the manipulation of the pulse number to control the amount of angular displacement, the intention to reach accurate positioning. Step motor has more advantages, such as: brushless structure, high reliability; the more traditional motorEasy to stop and rotary, dynamic echo fast; The suspension can self-locking, adhere to the torque, etc. At present, the market widely used stepping motor is in hybrid stepping motor (Hybrid Stepping Motor, HB Stepping Motor)With permanent magnet stepper motor (Permanent all Stepping Motor, a PM Stepping Motor), VR step motor is screening at all. HB stepping motor to finish very precise small incremental step distance movement, to the clutter, fine linear motion control requirements; PM stepping motor torque and the volume is relatively small, control accuracy is not high, the output torque is small, is a kind of cost is more economic. Due to technology development and application of industrial demand, PM stepping motor subdivided into linear and rotary type two kinds. Stepper motor industry chain scale of stepper motor is widely used, such as office automation, factory automation, medical apparatus and instruments, measuring instruments, Banks, ATM equipment, car, entertainment equipment, communications equipment, stage lighting, etc. The rise of new industries, such as 3 d printing, solar power, such as motor vehicle use invented new market space. Stepper motor industry development direction of future development trends of stepper motor is from open loop to closed-loop, integrated with drive and servo system integration development. Integrated development and stepper motor drives, and BIDCM (Rare earth permanent magnet brushless dc motor)Communication servo motor system combining with the development are the two important trends, stepping motor has been gradually using full closed loop control, has the function of the servo motor. In the future, step motor volume more dainty, function better and more cost-effective, will be in the home robots, civil mass use of intelligent equipment and other civilian equipment. Stepper motor industry development prospects with the progress of industrial automation level, the new economy, the demand for step motor is improved. Stepping motor has been penetrated into multiple and continues to deepen the economic category, such as computers, communications equipment, office automation, industrial automation, bank equipment category. Future, touches people daily life food, clothing, shelter and done a lot of production and in the escalating use category, new industry, will put forward new requirements to stepping motor. Forward-looking industry institute analysis thought, 2018 -In 2023, the stepper motor manufacture industry in our country the size of the market will stick to 5. About 1% of the average annual growth rate. Optimistic estimates that by 2023, industry market size is expected to break 18 billion yuan. The current overall, stepper motor production and demand is huge. Stepper motor is in addition to the direct current motor and communication outside the most widely used the third type of motor, the motor in open loop high resolution positioning system, has yet to find more suitable to replace its products, especially in some small power of the system, the mainstream of the stepper motor has no alternative location, so always have a large market demand. A nasty use category start motor is deepening, and create new market demand.
