Linear stepper motor directly serve system is nearly 10 years developed a kind of new type into contact transmission ways, in all kinds of high speed and precision machining on the wide application of former record, break system in machine tool & quot; A rotary motor + ball while bar 'feed drive way, due to limited by its own structure. In the feed speed, acceleration, the position precision, etc, it is difficult to have ever been sex, already cannot satisfy the ultra high speed cutting, ultra-precision machining machine tool feed system step by step seaborne performance put forward higher requirements. Linear stepper motor is a kind of mechanical energy convert electrical energy directly into linear motion, without any intermediate conversion mechanism of transmission. With starting thrust is big, high stiffness and dynamic response is fast. High positioning accuracy, jin cheng unlimited length encoding sorrow points, especially due to the high linear motor without heart function, so the eyes move straight male young speed can be not affected by system; And its very big, such as speed of up to 10 g (g = 9。 8m/s2）。 Can realize starting between pupil it to high-speed, high-speed run-time can instantly stop push again. Only at a high speed, therefore, Lai Mi machine tool feed system to use linear motor direct face move way, to achieve the required high feed rate and feed acceleration. But in the machine tool feed system to use linear motor direct drive mode will bring new contradiction and problem, main show is: fever. Magnetic isolation and protection, load disturbance and applied to the vertical feed mechanism of self-locking and gravity acceleration, to solve these problems is very important to the application of linear motor direct drive way, the working principle of linear motor and rotary motor, it also has the dc. 交流,步前进。 The permanent magnet. Electromagnetic. A variety of types such as synchronization and different step 'from its structure. It has dynamic surface type, moving iron type. Flat and cylinder type, etc. The development of linear motor has experienced a long history. As early as at the end of the old age 19 and 20 temple JiChu has been engaged in the research of linear motor. But did not succeed. 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.
