In recent years, with the development of high-energy permanent magnets at a low price and performance, makes use of permanent magnet synchronous speed regulating motor communicate with step by step into the system performance is increasingly prominent, to solve the problems of ac asynchronous step brings hope. Compared with the vector control of induction step by step, the permanent magnet synchronous motor rotor temperature is low, the axial connection position precision is high, the requirements of the cooling conditions is not high, the temperature of the environmental impact of nc machine tools is small, easy to achieve the minimum lower limit velocity.
even if under the low speed limit, also can make constant torque operation, especially suitable for machining. At the same time, its high torque density and moment of inertia of small, good dynamic response characteristics, especially suitable for high productivity. Is easier to achieve high speed ratio, allowing the same spindle has a variety of processing capacity, can be processing the low hardness of materials like aluminum, can also be very hard brittle metal processing, to create conditions for the optimal cutting machine tool.
at present, the machine is mainly used in feed step permanent magnet synchronous ac stepping system, there are three types: analog, digital and software. Simulation step USES a single, only to receive analog signal and position control is usually implemented by the upper machine.
digital step can realize multi-usage, such as speed, torque, and position control. Can receive analog instructions and pulse, various parameters are set in digital way, stability is good. Has a rich self-diagnosis, alarm function.
software step is full digital stepper system based on microprocessor. It will be all kinds of control mode and different specifications of stepping motor, power monitoring program in software implementation. When using can be set by the user code and the related data automatically. Equipped with digital interface, change the way we work, change the motor specifications, only need to reset the code, so also called universal step by step.
communication step has held the dominant position of machine tool feed step by step, and constantly improve, with the development of new technology embodies in three aspects.
a is the power drive system of the power electronic device continuously develop to the direction of high frequency, popularization and application of intelligent power module; The second is based on an embedded microprocessor platform technology mature, will promote the application of advanced control algorithm; Three is the development of networked manufacturing mode and the mature of field bus technology, will make the stepper control based on network is possible.
around stepper system dynamic characteristic and static characteristic, in recent years developed a variety of stepper drive technology. Four macro mechanical and electrical company supply MOONS integrated step progress motor TSM series, innovative to incorporated in the stepper motor, stepper control technology to create a new revolutionary integration of the excellent performance of motion control terminal. Especially the TSM series is the third generation integrated step progress motor products, integrated machine, integrated terminal; Intelligent, built-in motion controller; Bus control, multi-axis network communication; Enhanced motor, long life design; High efficiency, high precision, high response; Low vibration, low noise, low fever and other excellent characteristics.
the predictable with ultra high speed cutting, the ultra precision processing, network development of advanced manufacturing technology, such as manufacturing, has a network interface of the digital stepping system, linear motor and the high speed motorized spindle, etc will become the hot spot in the CNC machine tool industry, and become the stepping system 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. Telephone:
