Stepper Motor Reprap 3D17

Q: A problem with the zero detection of step motor: The step motor is different from the PG motor, which should not be tested for zero. An Index signal can be used as an internal reference point control if a more accurate closed-loop control is implemented.

Q: The step motor is more expensive than the reversible motor: The model price is different also, different brand also is different. And they're not a class of products. There's no comparison. It's not an occasion.

Q: What is a step motor: Stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller.

Q: What is the maximum speed of the 86 step motor per minute?: The speed of the step motor is not too small, depending on your load, and the 42 motors we have tested can go up to over 1,600

Q: Do you choose the step motor or the servo motor?: This is more suitable for servo motors. First, stepper motors have the largest start frequency, once above a start frequency can't start, that is to say, the stepper motor to achieve a certain speed need longer time to speed up the process. Relatively speaking, the characteristics of the stepper motor is high torque output is stable under the condition of low frequency, frequent positive &negative need motor has a very high response and high speed stability, this is not a step motor strengths, it is precisely the characteristics of the servo. In addition, the motor stator no direct contact, so there is no return gap problem, but frequent positive &negative, step step electricity opportunities have lost phenomenon. The server is given feedback by the encoder, so you can be completely satisfied with this issue.

Q: How do you calculate the inertia and torque on the output shaft of the motor: Every move slowly into the motor drive moment of inertia, mostly manufacturer tests, because there were some fuzzy parameters, the calculation of inertia force and the biggest difference is that moment of inertia is a set of quality area, torque is set the length of the unit quality. The formula is: the moment of inertia equals the mass of the object. The inertia of the step motor is produced by the rotor, so it is important to calculate the rotor weight of the step motor.

Q: What is the control of the frequency converter: Stepper motor control points several commonly: small power stepping motor generally + power tube directly by single chip microcomputer control, but this does not control the whole step control, does not carry on the current closed loop control, control is simple, but the machine effect is poorer, generally in the home appliances or request is not high application occasions; If required by the step running effect of small probability is higher, can use special chip to control the general current closed-loop control is realized by using hybrid attenuation method, but the working voltage and working current is lower, the main drive, 42 small motor etc; For stepper motor general over 57 special drive control method was adopted to realize closed loop control of motor current, control methods including hysteresis comparison, attenuation, current analog hybrid PI, full digital control method. The best control method is to use DSP control all-digital stepper drive, can have inhibition of the stepper motor vibration and noise, and fever, improved the performance of the step

Q: I have a step into the motor, I want to get him to work, what do I need to prepare, about the cost?: Although the stepping motor has been widely used, the step motor is not used as a normal dc motor and ac motor is used regularly. It must be used by the control system such as double ring pulse signal and power drive circuit. Therefore, it is not easy to use a good step motor, which involves a lot of specialized knowledge, such as machinery, electrical machinery, electronics and computers. Stepping motor is one of the key products of mechanical and electrical integration, and is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand for stepping motors is increasing, and there are applications in the national economy.

Q: Type: 103-845-02, 3VDC 6.7 A, 6 lines "red, yellow, blue, black, white, green", not knowing how to connect?: Six line is generally in the two groups, with multimeter pens and pick up one of the first line, and then, in turn, points the other lines, all of is another group, the remaining two are with you through this is a group of a group of the inside of the three lines, one of which is a center tap, use pens and repeated the test three lines, the largest is the coil resistance between the two ends of the tap, the rest is the center tap. This will determine the definition of all the lines!

Q: What is the reason for the stepper motor not running at high speed: What is the high speed specified? Stepper motor is a low speed high torque motor, the majority of applications in 600 ~ 1500 RPM range, provide equipment load is very light, to run high-speed, need to refer to the stepper motor torque of the condition of different voltage and frequency curve, if the device in high speed work need is smaller than the motor output torque, torque can work, otherwise the motor will be closed.
