China NEMA 17 NEMA 23 NEMA 34 Stepper Motor

Q:What are the step motor parameters and characteristics?: Some basic parameters of the step motor: Inherent step distance of motor: It means that the control system sends a pulse signal, the Angle that the motor spins. Motor factory is given a step away from the Angle of value, such as 86 byg250a type motor is given a value of 0.9 ° / 1.8 ° (half step work step 0.9 °, the whole work of 1.8 °), the interval Angle may call it the 'inherent interval Angle motor, it is not necessarily the motor when the actual work of real interval Angle, real interval Angle and drive on. Step motor: It refers to the number of coils within the motor, which are currently used in two phases, three phases, four phases and five phase stepping motors. Step motor phase number is different, it is apart from the different Angle, the general step of the two-phase motor pitch Angle is 0.9 ° / 1.8 ° and 0.75 ° of three-phase / 1.5 ° and 0.36 ° of five phase / 0.72 °. When the driver is not broken, the user mainly depends on the step of the different phase to meet the Angle of the step. If you use a subdivision drive, the "phase number" will become meaningless, and the user simply changes the score on the drive and can change the step Angle. HOLDING TORQUE:

Q:The step motor is widely used in any field: Widely used in the ATM machine, spraying machine, carving machine, pictorial machine, spraying equipment, medical instrument and equipment, computer peripherals and mass storage equipment, precision instruments, industrial control system, office automation, robots and other fields. It is especially suitable for the application of stable, low noise, fast response, long service life and high output torque.

Q:The difference between the servo motor and the step motor: I take it very seriously, to answer the question of science, to be sure, not to mislead the questioner, and the answers of these answers are misleading Performance comparison of stepper motor and ac servo motor The step motor is a discrete motion device that is intrinsically linked to modern digital control technology. In the domestic digital control system, the application of stepping motor is very broad. With the advent of full digital communication servo system, ac servo motor is increasingly applied to digital control system. In order to adjust to the development trend of digital control, most of the motor control system is used as an actuator motor. Although the two are controlled in similar ways (pulse train and direction), there are significant differences in performance and application situations. Now compare the performance of the two.

Q:What is the connection between PLC and motor, including ordinary motors and stepper motors. What is their power supply?: Contactor is electromagnetic switch, PLC provides only a small power switch, to control the intermediate relay, have intermediate control contactor, contactor to connect power, side of the motor, the controller, is to control the step motor, if you want to program, must provide detailed control requirements.

Q:What is a hybrid step motor?: Hybrid stepper motor: the step motor is divided into three types: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 1.5 degrees. The reaction type step is generally three-phase, can realize the big torque output, the step Angle usually is 1.5 degrees, but the noise and vibration are very large. Developed countries such as the United States and Europe were eliminated in the 1980s. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phase, three-phase and five phase: two phase stepper Angle of 1.8 degrees commonly and five phase stepping Angle of 0.72 degrees commonly, hybrid stepping motor as the increase of the number of phase (several) winding the power supply, the stepping Angle decreases, and improve the precision and the application of the stepper motor is more extensive

Q:What is step motor drive breakdown: As you can see in figure 3, the phase current of the step motor is distributed by the sinusoidal function (as shown in the dotted line). The larger the fraction, the closer the current is to the sine curve. Step 2: the relationship between the step motor and the motor stability is measured in the step distance of the motor, which is 1.8 degrees. At the time of the experiment, the motor speed was set to 2 r/s. When the motor 2 is subdivided, the motor is 400 steps per turn, and the cycle is 1.25 ms. When the machine is subdivided, the motor has a period of 0.3125 ms per step. When the motor 64 is subdivided, the motor has 12800 steps per cycle, 0.0391 ms per step period. When the step is subdivided, the current waveform step is uniform, and the current pulse is high, the maximum is 70.7% of the maximum current. When stepping into the 8 subdivision of the motor, the current waveform step is obvious, but the current ripple value is small, the maximum is 19.5% of the maximum current; Stepping motor subdivision, 64 current waveform is smooth, the current waveform has been difficult to distinguish, respectively, the number of steps, maximum current pulse is only 2.45% of the maximum current. By electromagnetic induction theorem, stepper motor output torque and motor coil current is proportional to the, and: T = KT * I type in the KT as the motor torque constant, it with the motor structure, the material, the length of the coil and other factors.

Q:What is the reason for the continuous burning of several steps: If the voltage is too high, the nameplate on the motor is rated at the rated voltage, unless the designer has a problem

Q:What happens to the step motor? What is the solution? Thank you very much!: There are several reasons: 1. Excessive load. The speed is too high. Increase the torque. Increasing the voltage of the driver can also be achieved

Q:What is the difference between a step motor and a 2380v: Stepper motor end using the pulse constant current source, the input ac just provide energy, 380 v input is smaller than 220 v input current is commonly used in big torque stepper motor drives. Suppose A 24 n. M stepper motor power of about 750 w, then using the 220 v power supply drive ac input current = 750/220 = 3.4 A, if you are using A 380 v power supply current = 1.732/750/380 = 1.14 A. That's the difference.

Q:The main shaft of the step motor is very tight, and the hand can't move when it is not energized: The normal step motor can be rotated by hand under the condition of power failure. You say that the main shaft step into the motor is different, generally vertical installation, with the brake, so the power failure condition can not move. Of course, if the machine does burn down the card, it will not move. To sum up, can't say "do not use the hand to turn the hand without the power" to think the motor must be bad.
