Stepper motor selection method --—Five steps: step 1: keep the torque stepper motor, similar to the 'power' referred to in the traditional motor. Of course, the distinction that having essence. Physical structure of stepping motor, is completely different from ac, dc motor, the output power of motor is variable. According to the need of torque size (usuallyTo drive the torsion of size)To choose what type of motor. Roughly speaking, torsion in 0. 8 n。 M below, choose 28, 35, 39, 42 (The fuselage diameter of the motor or degrees, unit: mm); Torsion in 1 n. 57 motor m or so, the choice is more appropriate. Torsion in several N. M or more, be about to choose 75, 85, 86, 90, 110, 130, and other specifications of the stepper motor. For motor speed also want special consideration. Because, the output torque of motor, and is inversely proportional to the speed. That is to say, step motor at low speed,Several hundred revolutions per minute or less speed, the output torque is larger)In a state of high speed rotating torque (- 1000 r/min-9000 RPM)Is very small. Of course, there are some conditions environment requires high speed motor, stepping motor to the coil resistance and inductance of indicators to measure. Choose the motor inductance smaller, as a high-speed motor, can obtain larger output torque. On the other hand, the requirements under the condition of low speed high torque, will choose inductance in more than a dozen or dozens of mH, resistance to a few bigger as well. Step 2: step motor no-load start frequency, often referred to as 'empty frequency'. This is an indicator of the more important the choose and buy motor. If required frequent start, stop, in a flash, and, in about 1000 RPM speed (Or higher), usually need to 'accelerating'. Directly if you need to start the high-speed operation, had better choose reactive or permanent magnet motor. These 'empty frequency' of the motor is higher. Step 3: the number of phase step motor 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 a two-phase motor (Four phase stepper motor)There are many. In high speed large torque working environment, choosing three-phase stepper motor is very practical. Step 4: special stepper motor can waterproof, prevent oil, used in some special occasions. Underwater robot, for example, you need water machine. 75 byg series motor is mostly waterproof structure. For special purpose machine, will be targeted to choose from. Step 5: special specifications of the stepper motor, usually need to communicate with the manufacturer, in technology allow, within the scope of the processing order. For example, the shaft diameter, length, stretched out direction, etc. 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.
