3D printing is usually achieved using digital technology material printers. Often used in mold making, industrial design and other fields to manufacture models, and then gradually used in the direct manufacture of some products, there are already printed parts using this technology. Known technology applications range from desktop level to industrial level, with product segments as large as aerospace, automotive, and construction engineering,
Small to jewelry, shoes. Dental and Education. The 3D printing we will discuss today is not only for industrial applications. At present, many 3D products that can be touched by family life have been reported by the outside world, such as food, clothes, shoes and even houses. This article will elaborate the trend and future of 3D printing at home. We have all kinds of motors for printers in our factory.
At present, the mainstream 3D printers are using subdivision drive technology, which can greatly improve the stepping moment resolution of the stepper motor, reduce torque fluctuation, avoid low-frequency resonance and reduce operating noise, so that the 3D printer can reduce noise. Subdivided driving technology is a kind of current waveform control technology, the basic idea is to control each phase winding current waveform, up or down the ladder, namely between 0 and maximum given multiple steady states in the middle, in the process of the rotation of the stator magnetic field also have multiple steady states in the middle, corresponding to the increase in the number of step motor rotor, interval Angle decreases. Medium,V motor speed (R/S), P pulse frequency (Hz); θe~ intrinsic step Angle of motor; M - Fine fraction.
