Modern communication stepper system with high efficiency, has experienced the transition from analog to digital, digital control loop is ubiquitous, commutation, current, speed and position control; Using new type of power semiconductor devices, high performance DSP and FPGA, and step into the special module (Like the IR launched special stepper control engine)It is not surprising. Use of magnetic materials different function, different shapes, different surface bonding structure (SPM)And embedded permanent magnet (IPM)Flush of motor rotor structure, split type iron core structure the use of technology in Japan to make the fruit of the brushless permanent magnet stepping motor to realize the high efficiency, large quantity and automation, and cause of collecting manufacturer. Whether brushless permanent magnet stepping motor is still a step motor is positive to the smaller the size of the development, like 20,28,35 mm outside diameter; Also in the development of more powerful and size of the model, has seen 500 kw of permanent magnet stepper motor. But this way in the face of greater technical challenge,Such as reliability)And engineers use habits of challenge, so it is difficult to become mainstream, in the whole step market has distinguishing feature is a small unit. Mainly includes high efficiency motor itself is like function of permanent magnetic material to improve and better the magnet installation structure design, including driving system of high efficiency, including the inverter drive circuit optimization, optimization of deceleration motion, regenerative braking and energy feedback and better way of cooling, etc. Sometimes we call this integration and communication of motor intelligent motor (智能电动机), sometimes we call integrated motion control and communication drive intelligent stepper motor drives. Follow the need of large-scale distributed control device of rising demand, the successful development of high-grade CNC system, the development of networked digital step has become the top priority. Reflecting the development tendency to heal. Integration and integration and higher accuracy of the encoder (Turn every million pulse)Digits, faster, higher sampling precision and data of DSP, no the cogging effect of high functional rotary motor, linear motor, and the application of adaptive control, artificial intelligence and other modern strategy, will step into the system of indicators of progress. Motor, drive and control from design, manufacturing to the integration of three operation and maintenance are more closely integrated. Intelligent universal drive configuration has a large number of parameters and rich menu functions, making it easy for users to under the premise of without changing the hardware configuration, the land was set to V/F control, open loop of speed sensorless vector control, the closed-loop flux vector control, permanent magnet brushless ac stepping control electric thoughts and regeneration unit five kinds of works, such as applied to various occasions, can drive different types of motor, asynchronous motor, permanent magnet synchronous motor, brushless dc motor, stepping motor, also can adapt to different sensor types even without position sensor. Modular refers not only to stepper driver module, power module, regenerative braking module, communication module between combinations, and refers to the stepper motor drive internal software and hardware modular and reusable. You can use the motor itself, constitute a half closed loop feedback control system configuration, also can through the interface and external position or speed or torque sensor constitute a high precision closed loop control system. Network and modular modern communication stepper motor drives have parameters memory, fault self-diagnosis and analysis function, the vast majority of the entrance to the drive has function of load inertia measurement and automatic gain adjustment, some can automatically identify the motor parameters, automatic determination of encoder zero, while others can automatically suppress vibration. International manufacturers step product every five years will, every 2 ~ 2 new power device or module. Will update once 5 years, new software algorithm is rapid, short product life cycles are getting shorter. Generalized electric thoughts, feedback, vertical integration of control, drive, communication has been becoming the current low power stepper system of a development direction. 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.
