Stepper motor, synchronous motor and the product of digital control technology combined together. A standard of permanent magnet synchronous motor, driven by square wave drive or staircase and positioning (Current state)Control, is a devoted into the motor. In order to improve the resolution and improve the torsional rigidity and to increase the number of, often using magnetic resistance type and hybrid (Permanent magnetic induction type)Structure, and permanent magnet pole motor, there is no difference in principle. at present, the development direction of stepper motor and the development direction of the future may mainly has the following three points: (1)Perfecting and expanding further drive and control functions. Such as adopting SVPWM technology, the use of electronic gear than technology, expand communication network function, etc. ; (2)High power density of the stepping motor system. at present main products are stepper motor 50 of a synchronous motor, torque density is high, but the power density is rather small, so the high power density under the condition of certain step products could be developed; (3)Closed-loop control stepping motor system. In order to completely overcome step department unified some fundamental weaknesses, such as the tendency of oscillation and step out, can be changed to closed loop system, but the change of stepper motor system has been a qualitative change, is no longer the original sense of the stepper motor, and become a brushless dc motor (BLDCM), or ac stepping motor (AC servo)。 in the late 1960 s to the early 70 s, the stepping motor products began to mature, successful application, and fairly quickly developed into a certain scale of industry. Stepper motor is suitable for small power high resolution open loop positioning system, its characteristic is: open-loop system requires little debugging; No long-term accumulated error; Positioning state stability is good; Simple system, low cost. So in the digital motor control system always occupies very important position. after 30 years of development, the stepper motor technology and products, has been so perfect, mainstream products is 50 tooth of two-phase hybrid stepping motor drive system with current type micro step function. Another 50 tooth with a small amount of 5 phase hybrid stepping motor series products and developed a decade ago to 50 teeth three phase hybrid stepping motor series products. Shanghai four macros stepper motor, stepper motor drives, Shanghai four macro motor using permanent magnetic silicon steel sheet and Japan NSK original bearing manufacturing, has high positioning accuracy, high output torque, high response frequency, running low noise, good dynamic characteristics and advantages. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
