Hybrid Stepping Motor H421 (42MM) - Nema 17

Q:How do you solve the screw sloshing of the straight line of the shaft?: Stepper motor is the default step 1.8 ° Angle, 360/1.8 = 200 pulse, so the default is 200 pulses a stepping motor, but in some institutions require high precision, 1.8 ° doesn't fit, so there will be a drive the segment above Settings, such as the drive with a 1000 (or 5) segmentation, is 5 times Angle reduces is 1.8/5 = 0.36, every step is refers to the motor rotation Angle is 0.36 °. That's a five fold increase in accuracy. And current, the stepper motor has A rated current, such as A click of the rated current of 4 A, if you are in the drive selected above is 2.25 A, then the strength of the motor can't reach the moment of it, but you set it to 5 A, while the strength, fever also become bigger, but relative to the motor current this setting needs to set up according to actual situation.

Q:What is the difference between the two phase stepping motor and the four-phase step motor?: The dual-polarity drive can drive a single polarity motor, but a unipolar drive cannot drive a bipolar motor. To put it bluntly, four phases of maeda draw two lines in the middle of the AB winding.

Q:How to control step motor? I'm going to make a smart blinds to stop the motors: Motor head need to stop the travel switch can be used in control, motor speed is slow, can the wheels of the motor shaft with a freshman, the wheels with other devices can be used in.

Q:What is the control of the frequency converter: It is controlled by the driver of the step motor. The main function of step motor drive breakdown is to improve the precision of stepping motor. It usually subdivided by 2, 4, 8, 16, 16, 32,62,128,256,512... In foreign countries, the step system is mainly adopted by the two-phase hybrid step motor and corresponding subdivision drive. But in domestic, the masses of users to understand "segmentation" is not special, just think, segmentation is in order to improve the accuracy, actually otherwise, segmentation mainly is to improve the performance of the motor, the instructions are as follows: stepping motor subdivision control is precisely controlled by the driver of stepping motor phase current, the two-phase motor, for example, if the rated current of motor is 3 a, if you are using a conventional drive (such as a common mode of constant current chopper) driving the motor, every step motor running, in its winding current will mutations from 0 to 3 a or 3 a mutation to 0, the great changes in phase current, is bound to cause vibration and noise of motor running. If using subdivision driver, under the conditions of 10 subdivision drive the motor, step motor each run A micro, current changes in the winding is only 0.3 A, rather than 3 A, and the law of electric current is A sine curve changes, thus greatly improve the motor vibration and noise,

Q:How much static torque a motor can have when it is cut off: The moment of the power failure is the torque of the motor itself, which is the force of the rotor without the electricity

Q:How to determine which is the phase A and B of the two phase four step motors?: It's not clear your question; A four-wire step motor is represented by two winding coils in the motor, usually labeled "A +; A -; B +; B - '", which can be measured by A meter. If there is no multimeter in the field, you can also shorten two sets of two lines. If the motor is unable to rotate, the two lines representing a short connection are the same set of winding;

Q:The difference between stepping motor, steering machine, servo motor?: Steering gear (electronic steering machine) : the main component of the steering machine is servo motor. It contains servo motor control circuit + reduction gear group. Oh, yes, the servo motor has no reduction gear. The steering gear has a reduction gear. If it is a limit steering machine, determine the steering Angle by the potentiometer below the output shaft. Steering signal control is a kind of pulse width modulation (PWM) signal, which is easily generated by microcontrollers.

Q:What are the advantages and disadvantages of stepping into the motor?: I pour you into the motor like garbage, but the most common thing on the market is the stepping motor. There is no benefit of stepping into an electric motor. The greatest advantage is that you can pinpoint it.

Q:How does the two phase step motor connect: Four lines, two for one phase. Choose two lines for one phase (A phase) and two for B. There are three states, 1. The motor runs normally. The motor is operating normally but the reverse is reversed, and then the machine is chosen for a phase 2 wire and the motor can be transmitted. The motor jitter does not work, the A phase any line with B should be interchanged

Q:Is the stepping motor way?: Double phase double triple beat, its electric sequence is AB - BC - CA - CB This way of electricity because of the two phase electricity at the same time, the rotor by the induction of torque, static error is small, high positioning accuracy, and there is always a common electricity transformation, can work stable, not easy to out of step. Three, three, six beats, the order of the electric power is A - AB - B - BC - c-ca - A This is a single, double-phase alternating current, which has a double beat, and is doubled by the number of current states, and reduces the Angle of the step twice.
