Stepper Motor Reprap 3D17

Q: What is the principle of the three-phase six-step motor?: The step motor is a discrete value control motor that converts the electrical impulse excitation signal into the corresponding angular displacement or line displacement. This motor moves one step at a time when it enters an electrical pulse, so it is called the pulse motor. The rotor of a stepper motor is made from a flexible magnetic material or permanent magnetic material, and the stator is fitted with a multi-phase control winding. Its excitation signal has dc pulse, square wave, multiphase square wave and logical sequence. The step distance and velocity of the step motor are not affected by voltage fluctuation, ambient temperature and load change, but only with pulse frequency. Changing the pulse frequency can adjust the speed of the motor in a large range. As a result, the step motor is used to open loop digital control, which greatly simplifies the control system. Stepper motor with position detection device can also be used for closed-loop digital control, commonly used in printers, and tape reader, counters, drawing machine, CNC machine tools, valve actuator, positioning platform and digital to analog converter, etc. There are various kinds of stepper motors, and they are divided into rotating stepper motors and linear stepper motors

Q: I just want to know, how many pulses does it take to get into the motor?: Two phase stepper motor, the step (understandable subdivided into 1), one revolution of the 200 pulse interval Angle is 1.8 °, 360 ° / 200), half step interval Angle is 0.9 °. The corresponding three-phase step motor, the whole step 300 pulse a circle. Subdivision steps behind can intuitive see corresponding segment, the step is to give much pulse went a circle, such as 2 behind segment is 400 steps, which means 400 pulse motor turns a circle. The number of steps in the following is a description of the segmentation, which is aimed at reducing the low frequency vibration and noise of the stepping motor. It's a little messy, I hope you can help.

Q: What do you mean by step motor? Two phase stepping motor and three-phase step motor: It is not possible to do so at the moment, only each phase is directed by a certain order. Notice stepping in the name of the motor, step by step, electromagnetism is the electromagnetic relationship, electromagnetic objectivity. Stepping motor is only the tip of the iceberg. Don't feel abstruse and know the rules, you don't ask. The best don't ask such a low level question.

Q: What is the difference between a step motor drive and a controller: If the motor is a fist, the controller is the brain, the driver is the muscle.

Q: What is the main application of stepper motor?: The motor is operated under 600 PPS (0.9 degree) and should be driven by low current, large inductance and low voltage. Should follow the principle of electing electric motor first. Motor mountain club is a professional research and development, sales and marketing of stepper motor high-tech enterprise, supply high quality stepper motor, and high quality service at the same time, the products are widely used in automation control, medical equipment, textile machinery, packaging machinery and other fields.

Q: What is the step motor? What is it used for?: The permanent magnet step is generally two phases, the torque and volume are smaller, and the step distance is usually 7.5 degrees or 15 degrees. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phases, four phases and five phases: the two phases are normally 1.8 degrees and the five-phase Angle is 0.72 degrees. This step is the most widely used. The phase number of the step motor is the number of coils within the motor, and the two phase, three phases, four phases and five phase stepping motors are commonly used. The number of the motor is different, the Angle of the step is different, the Angle of the step distance of the second phase motor is 1.8 degrees, the third phase is 1.5 degrees, and the fifth phase is 0.72 degrees. In the absence of a breakdown driver, the user mainly selects the steps of different phases to meet the requirement of the step Angle. If you use a subdivision drive, the number of phases becomes meaningless, and the user simply changes the score on the drive to change the step Angle.

Q: Type: 103-845-02, 3VDC 6.7 A, 6 lines "red, yellow, blue, black, white, green", not knowing how to connect?: So you can according to your stepper motor nominal test your motor, this motor nominal voltage is 3.6 V, so I just use 5 V dc regulated power supply to test, the method is as follows: 1, first connect the two coil center tap and 5 V power supply of the anode (also can be negative); 2, with the power supply cathode to touch the other four thrum, touch once, look at the motor forward or reverse, if is positive, then meet again next, see is or was, the means of this line is not what you need at present, was, is, and then back to a process, just confirm it. This way, you can determine the driving order of the step motor. Here introduces a small detail, also is the need to the motor shaft with a small label, to facilitate observation of motor rotation, I began to no label, thought motor without rotation, is discouraged, then think of something, as if heard the noise of motor internal rotation, then I think because of the rotation Angle is small, the naked eye is not easy to detect, so I just posted a indicator label on it, this time really touch line is found, the motor have rotational Angle:) it's the test result is: four phase sequence is: blue, green, yellow and red.

Q: Is the stepping motor way?: It is usually powered by a dc switch, and a computer sends a pulse signal to drive the step motor

Q: Do you need a speed reducer to step into the motor? What is the effect of a speed reducer?: Look for the torque that you need, if you go beyond the range, the only object is to increase the torque. Step by step motor is an open loop controlling element which converts electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.

Q: The step motor and the servo motor are big: Running performance different ac servo drive system for closed-loop control, the drive can be directly to the motor encoder feedback signal sampling, internal position loop and speed loop, general won't appear step motor lose step or overshoot phenomenon, more reliable control performance Stepper motor control for the open loop control, start frequency is too high or too much load step easy appear lost or blocked, stops frequently occur high speed overshoot phenomenon, so as to ensure the control accuracy, should handle the ascending and descending speed problem Speed response performance better acceleration performance of the ac servo system, different from the static accelerated to the rated speed 3000 RPM it takes only a few milliseconds, can be used for quick start-stop control occasions Stepper motor accelerate from 0 to work speed (generally for a few hundred revolutions per minute) 200 ~ 200 milliseconds
