Q:What is the difference between a step motor six and four
Stepper motor there is a vast difference between four and six lead wire, with four lines there are two possible, one kind is bipolar, that is, four line and outlet is four wire. The second one is the unipolar, the line four. There are two possibilities for the sixth line, but they're both bipolar motors, and they're just different. The difference between two phase four and two phase six steps: The same thing, the six-wire machine can be connected to four lines. The driver of the six-wire machine can only use the six-wire machine, but the four-wire motor can be driven by a six-wire machine and a four-wire machine. This is the difference between the half-bridge and the bridge. The six-wire motor actually pulls two heads out of the two winding of the four-wire machine. If you have to say the difference, the six-wire machine is more suitable for running than the four-wire machine.
Q:What is the difference between a step motor and a servo motor and a three-phase asynchronous machine?
Fundamental classification of electrical machinery 1, divide by the input current Dc motor Principle: the input current is dc through the brush and the commutator segment so that the motor rotor continuously gets the same current. Advantage: the speed regulation scope of dc motor is broad, the speed adjustment characteristic is smooth, the overload ability is stronger, the starting and braking torque is larger. Disadvantages: because the brush is easily worn, the motor life is not high. And dc motor is relatively low power. 2) alternator Principle: the input current of ac, electromagnet for instead of permanent magnets, the ac signal is loaded into the motor stator rotating magnetomotive force generated, so that the motor winding is constantly cutting magnetic field force. Advantage: high life, high power, not easily damaged by large current shock, cooling braking is more convenient. Disadvantages: low precision and low speed regulation performance.
Q:How does sanyo go into the motor?
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:What is the difference between step motor control and servo motor control?
Different control accuracy Two-phase hybrid stepper motor step Angle is 3.6 ° and 1.8 °, 5 phase hybrid stepping motors interval Angle is 0.72 ° and 0.36 ° in general. There are also some high performance steps in the step of the motor. The control accuracy of ac servo motor is guaranteed by rotating encoder on the back end of the motor shaft. Panasonic digital ac servo motor, for example, in line with standard 2500 encoder of the motor, drive due to the internal used four frequency multiplication technology, the pulse equivalent to 360 ° / 10000 = 0.036 °. For with 17 encoder of the motor, drive each receive 217 = 131072 pulse motor turns a circle, namely the pulse equivalent to 360 ° / 131072 = 9.89 seconds. Interval Angle is 1.8 ° is 1/655 of the pulse equivalent of stepper motor.
Q:How do you control step by step motor?
The control system sends a pulse signal through the actuator, which causes the step motor to rotate the Angle. So the speed of the step motor is proportional to the frequency of the pulse signal. To control the frequency of the step pulse signal, the speed adjustment of the motor can be precise. To control the number of step pulse, the purpose of precise positioning of the motor is possible.
Q:What is the connection between PLC and motor, including ordinary motors and stepper motors.
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:How does the step motor achieve position control
Ha! Ha! If you want an accurate position control it's not just about stepper motor control circuit with you, because of stepper motor step but a common thing and also is a bad deal with problems. This can only be reduced to the lowest level in the control method, if you want to be precise in position control, preferably with a closed-loop scheme. Because the control of this step motor is the product of the number of pulses that are given and the step Angle of this step into the motor to be converted to your actuator. Ha! Ha! Just fear that when resistance is large, you give the pulse but it can't move.
Q:What is the difference in performance between the three-phase step motor and the two-phase 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.
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:This paper summarizes the characteristics and advantages and disadvantages of the stepper motor motor
Step Angle: corresponding to a pulse signal, the angular displacement of the rotor of the motor is expressed in theta. Theta = 360 degree (the number of rotors), in the case of the normal two and four phases, the rotor teeth are 50 teeth motor. Four run time interval Angle is theta = 360 degrees/(50 * 4) = 1.8 degrees (commonly known as a whole step), eight beats runtime interval Angle is theta = 360 degrees/(50 * 8) = 0.9 degrees (commonly known as half step). These two concepts clearly, after we again to calculate the rotational speed, with basic steps within 1.8 ° Angle of stepping motor as an example (now in the market of conventional two, four basic steps from the Angle of the hybrid stepping motor is 1.8 °), four phase eight running mode, each receives a pulse signal, around 0.9 °, if receive 400 pulses every second, so speed is 400 megabits per second x0. = 9 ° 360 °, equivalent to turn every second, every minute 60. Other things can be calculated.
