挑选合适的步进电机和驱动器（Select the right stepper motor and drive） Engraving machine beginners must see teach you how to choose the appropriate stepper motor drive Part one: Introduction 1 、 stepping motor Lets talk about the dimensions of the stepper motor. 57, 60, 86, 110, and so on, say the diameter of the motor Machine. Square, usually width, in units of mm. After the width has been determined, the dimensions to be determined are Its length. 57 and 60 are generally between 40-100mm, 86 are between 60-130, and 110 are above 200mm. Of course, these lengths are more than Ive seen, and so are other lengths. The larger the average size of the motor, the greater the torque. When it comes to shape, some say round motors are weak and square powerful. I dont think this statement is complete Thats right. It needs some restrictions. In my contact with the motor, the general earlier Dongfang motor use more circular, then by the permanent magnet material limit, indeed the motor torque is relatively small. Later, the east of the motor basically used square, and technical progress, almost the size of the motor is significantly higher than the circle. But its also for the family. I have seen the 110 step motor in the American Pacific. Its torque has reached 20Nm, but its shape is also round, and SANYOs new stepper motor also has a round shape, and its torque is a little small. So, to see the torque, or mainly to determine its approximate year, the more new the same size, the torque will be greater. There is the stepper motor current, the size of the current determines the high speed performance of stepper motor, The higher the rated current, the better the motor speed performance. There is also a knowledge of current, which is the same factory, The same size stepper motor, although its rated current is different, but its torque is almost the same, the difference is that high-speed motor performance. Besides, the number of stepper motors. In general, we come into contact with the secondary
