Stepper Planetary Gear Motor (H281-1) 28mm

Q: How to reduce the S to the actual step motor control!: In addition, you can refer to the instructions of the panasonic A5 servo drive specification for the speed S curve setting parameters, which will help you understand the above. Hope to help you.

Q: Multiple step motor synchronous rotation: This is easy to implement, stepping motor model parameters is the same (best high consistency stepper motor), drive type and set the same parameters, the controller program parameters are the same, suggest that in the same way pulse control multiple drives, multiple drives again (each drive and drive 2 ~ 3 stepper motor). Disadvantages: the pulse voltage must be high, the control current needs to be improved, the drive current must be large, the motor must work under the rated current.

Q: Can a pulse signal from a PLC be given two steps at the same time?: First: your accuracy is low, and the speed is unpleasant. Second: two motors must be synchronized

Q: Can the numerical control system for stepping into the motor can be used for private motor: No, because the step motor is an open loop system, and the servo motor needs a closed loop system.

Q: What does it mean to step into a motor: Step number: refers to the number of wires drawn from the motor. The phase number of the step motor: the number of coils inside the motor, the two phase, three phases, four phases and five phase stepping motors are commonly used. 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 °

Q: Why is the first step always receding when the motor is on the power supply, and moving forward: In general, without electricity, stepping motor is relaxed, not necessarily in any Angle. And the starting position of the battery is set by the hardware and software in the controller, and certainly not exactly the same Angle that it stopped. So when you get on the electricity, you're always going to move. But this "move" does not always have to be "backward". It happens that you're "always backing away". If software design is clever, this can be eliminated. Method is: before each blackout, the Angle of the software to record the current (phase) stored in the nonvolatile memory block (EEPROM), and just read the last saved when electricity phase, according to the given initial drive electrical signals. This way, you can't "move" when you are on electricity, as long as there is no external force on the motor during the power outage.

Q: How do you solve the screw sloshing of the straight line of the shaft?: Modern segmentation of the principle of stepping motor is the same in different in different value of current, torque direction changing make their synthesis, thus in the original "whole steps" is divided into several stages, between such as ten step by step. The first step is to minimize or even completely avoid the wobble of the step motor, while also getting a smaller step. The current changes in each phase are generally sinusoidal. The sine of several phases is uniform. It took a lot of effort to realize the fact that the sinusoidal changes in the phase of the phase transition were achieved through more complex circuits and software. There are now many specialized integrated circuits, but they are basically Japanese, American and German. To is not expensive. It's very convenient. So, a lot of modern step motors are driven by segmentation.

Q: The step motor dc motor comparison and its advantages and disadvantages: The dc motor is controlled by the voltage of the motor, which is the command variable in position or velocity. The dc motor needs feedback control system and he controls the position of the motor in an indirect manner. The stepping motor system is operated in "open loop mode".

Q: Why does the stepping motor stop the brakes: Stepping motor: The step motor is an open loop controlling element which converts the 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: What is the torque of the step motor: The working principle of Normally the rotor of the motor is the permanent magnet, and when the current flows through the stator winding, the stator winding generates a vector field. The magnetic field will drive the rotor rotation, which will make the rotor's magnetic field go in the direction of the stator's magnetic field. When the stator's vector field spins an Angle. The rotor also moves in an Angle with the field. Each input an electric pulse, the motor turns an Angle further. The angular displacement of the output is proportional to the number of pulses in the input, and the speed is proportional to the pulse frequency. Change the order of the winding, and the motor will reverse. The rotation of the step motor is controlled by controlling the number of pulses, the frequency and the electrical sequence of each phase winding of the motor.
