Q:What do you mean by step motor?
Said stepping motor phase number is the number of motor coil winding, two phase two sets of coil, three phase three groups namely, power supply depends on the drive circuit, not directly on the motor.
Q:The application and applied advantages of stepping motor
Defect 1. It is difficult to operate at a high speed. It's difficult to get a big torque There is no advantage in volume weight, low energy utilization. More than the load, the synchronization will be broken, and vibrations and noise will be emitted at high speed.
Q:What is the reason for the stepper motor not running at high speed
Analysis of stepping and missing steps of stepping motor: Step 1: in the wrong type of motor, the inertia of the motor moment is not enough, or the inertia of the motion of the object exceeds the self-locking force of the motor, causing the lost step or the lost step 2: drive improper selection, form a complete set of drive current is small, affect the normal operation of motor, now on the market a lot of drive current virtual target, take a peak current when the rated current to fool consumers, drive type rated current should be greater than stepper motor 1.2 1.5 times rated current 3: the auxiliary power source is not suitable, and the auxiliary power supply should be 1.5-2 times the rated power supply of the driver, which is more serious than the imaginary mark The control part should be excluded from interference, away from the frequency converter, antistatic. The equipment can be ground to ground processing, prevent the inductive power, the signal line is done to block processing, set up the proper start frequency, and do well to add deceleration
Q:The speed of the step motor and servo motor is respectively
Stepping motor is a kind of actuator that converts electrical impulses into angular displacement. When stepping drive receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (called "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:How to control step motor? I'm going to make a smart blinds to stop the motors
First answer your first question, how to control the step motor, there are two ways: one is make your own driver circuit, there are many online information, this may not be stable, not recommended. The second is the use of the external manufacturer's drive device, the 51st chip machine as the main control system, through the communication interface to control the motor. This approach is simpler than development Intelligent curtain you said is which kind of, is the horizontal pull, or vertical lifting, in either, can through the sensor (limit switch) way to deal with to stop and start. The third question, motor speed is slow, it is related to your driver circuit and program, the speed of the motor depends on the pulse frequency, you give the information of some fuzzy, the specific issues that need to be combined with your current situation to judge. Keep in touch if you need to
Q:Why do we take the small step Angle
Step distance, the smaller the Angle, the higher positioning accuracy, we step distance of two-phase hybrid stepping motor Angle is 1.2 degrees, usually through each step we step subdivision drive can reach minimum 0.009 degrees or less
Q:The step motor and the servo motor are big
Servo motor stepper motor Different control precision Ac servo motor control precision is interval Angle is 1.8 ° of the stepper motor pulse equivalent 1/655 of two-phase hybrid stepper motor step Angle is 1.8 ° and 0.9 °, 5 phase hybrid stepping motors interval Angle is 0.72 ° and 0.36 ° in general. There are also some high-performance stepper motors that are smaller by segmenting the back step The low frequency characteristics of the ac servo motor are very stable, and even at low speeds there is no vibration. Ac servo system has a resonance suppression function, can cover the mechanical rigidity, and internal system has the function of frequency resolution (FFT), can detect the mechanical resonance point, is advantageous for the system to adjust stepper motor at low speed is easy to appear low frequency vibration phenomenon. The vibration frequency is related to the load condition and drive performance, and the frequency of vibration is generally considered to be half the frequency of the motor. The low-frequency vibrations, determined by the principle of stepping motor, are very bad for the normal operation of the machine. When the stepper motor work in low speed, general damping technology should be adopted to overcome the low frequency vibration phenomenon, such as add damper on motor, or drive the segmentation technology, etc
Q:What happens to the step motor? What is the solution? Thank you very much!
Step 1 increase torque (device driver is reasonable), 2 check the line to have interference, 3 check program is accurate, 4 contact step motor manufacturer to replace electric motor
Q:What is the phase number of the step drive motor, and how does the user select several phases of step motor?
To understand the number of phases of the step motor drive, the first step is to understand the phase number of the step motor, which is the number of coils. Several phases of stepping motor are matched with several phases of drive. Two, three, four, five stages of the motor are two, three, four, five sets of coils. N phase stepper motor windings have N, N the windings shall be evenly embedded in the stator, so the number of stator poles must be N integer times, therefore, the steps of one revolution of the rotor should be integer times of N; That is to say: the steps of one revolution of the three phase stepper motor is integer times of 3, 4 steps one revolution of the stepper motor is 4 integer times, the steps of one revolution of the five phase stepper motor is 5 integer times; If the basic step for developing the stepper motor is apart from the Angle of theta, round number is M, the number of phase step motor is N have the following relations: theta = 360 / M for these mechanical symmetry principle, M is necessarily phase number N integer times. As you can see from the above analysis, the base step Angle cannot be arbitrary. There is no necessary connection between the wiring and the phase number of the step motor. It depends on the actual application.
Q:It's a reasonable step in the acceleration of the motor,
While selecting a stepper motor, usually because of the stepper motor can't work in the same direction for a long time running, easy to heat up, life), so the stepper motor using occasions are usually short run, namely in the running, time is short, considering the moment, time also is the important factor to consider.
