Stepper motor when choosing stepper motor don't know what to do, it doesn't matter, step 5 teach you choose good stepper motor step 1: keep the torque stepper motor holding torque, equivalent to the traditional motor said & other; Power & throughout; 。 Of course, they are the distinction that having essence. Physical structure of step motor, is completely different from the ordinary ac, dc motor, its output is variable. Usually according to the size of torque of need, to choose what type of stepper motor. In general, torque at zero. 8 n。 M here, generally choose 28, 35, 39, 42; Torsion in 1 n. 57 motor m or so, the choice is more appropriate. The torsion in the few N. M or more, you should choose the bigger torque, 75, 85, 86, 90, 110, 130, and other specifications of the stepper motor. At the same time, we also should consider the speed of the machine. Because, the output torque of motor, and speed is inversely proportional to the relationship. Step 2: empty frequency step motor no-load start frequency, generally called & other; Empty the frequency & throughout; 。 This is to choose an indicator of stepper motor is very important. If required frequent start, stop, in a flash, and the speed at 1000 r/minutes or more. Had better choose reactive or permanent magnet stepper motor, the motor & other; Empty the frequency & throughout; Are high. Step 3: number phase stepping motor phase selection, the content, many clients have little attention, mostly buy casually. In fact, the number of different phase motor, working effect is different. Phase number, the more the interval Angle is small, can do the work of the vibration is relatively small. Most occasions, the use of two phase, three-phase, five more for the hybrid stepping motor. In high speed large torque working environment, choosing three-phase stepper motor is very practical. Step 4: waterproof anti-corrosion waterproof anti-corrosion type stepping motor can waterproof, prevent oil, suitable for some special occasions. Underwater robot, for example, you need water machine. Most 75 byg series stepper motor with waterproof structure. For special purpose machine, will be targeted to choose from. Step 5: special specifications, special specifications of the stepper motor, usually need to communicate with the manufacturer, within the scope of the technology that allows, processing customized. For example, the shaft diameter, length, stretched out direction, etc.
