The reversing vibration of the stepper motor is large...

When the load is heavy, especially when the timing belt is attached, too rapid reversing can cause large movements. The solution is to tighten the timing belt, decelerate for a longer time, and accelerate for a longer time. It is best to stop for more than 50ms in the middle of the conversion.

Adjust the acceleration and deceleration time a little more and try it.

There may be several reasons why the stepper motor just vibrates and does not rotate:1Insufficient drive current:

The stepper motor needs enough driving current to generate a magnetic field during normal operation, which drives the rotor to rotate. If the drive current is insufficient, the stepper motor may only vibrate and not rotate. Check whether the current setting of the motor driver is correct, if you need to adjust, you can refer to the rated current and working voltage of the motor to adjust.

2.Motor wiring error: The direction of the two-phase current of the stepper motor should be consistent, otherwise it will cancel each other out, causing the motor to just vibrate and not rotate.

Check whether the motor wiring is correct, you can use a test tool such as a multimeter to check. 3.Excessive load:

Excessive load on the stepper motor may cause the motor to simply vibrate and not be able to rotate. Check whether the load exceeds the rated load range of the motor, if you need to adjust the load, you can consider using a reducer or other mechanical transmission devices to reduce the load. 4.

Mechanical failure: There may be problems such as jamming or wear between the rotor and mechanical parts of a stepper motor, which can cause the motor to simply vibrate and not rotate properly. Check whether the mechanical parts are normal, if you need to repair it, it is recommended to seek help from professional technicians.

To sum up, the stepper motor only vibrates and does not rotate may be caused by insufficient driving current, motor wiring error, excessive load or mechanical failure, etc., which need to be investigated and solved according to the specific situation. If you are not familiar with the repair and troubleshooting of motors, it is recommended to seek help from a professional technician.

Hello, the reason why the stepper motor just vibrates and does not rotate is 1One of the phases inside the motor is damaged, resulting in the lack of phase of the motor and the inability to rotate normally. 2.

Poor wiring contact of the motor leads to phase loss. 3.The four wires of the motor are connected to the wrong sequence of the bending wires, which causes the two-phase windings of the motor to be unable to supply power normally, and the motor jitter.

Jan Jing 4The stepper motor driver is damaged and cannot drive the motor properly. Dear, the above is the answer to your question, do you have anything else to ask.

The vibration of the stepper motor after driving is large, usually because the motor is running at low speed (at the resonance point), and the vibration and noise of the stepper motor when rotating at low speed are its inherent shortcomings, which can generally be overcome by the following schemes:

1. If the stepper motor is working in the resonance zone, the resonance zone can be avoided by changing the mechanical transmission such as the reduction ratio;

Second, the use of the driver with subdivision function, this is the most commonly used and most convenient method;

3. Replace with a stepper motor with a smaller step angle, such as a three-phase or five-phase stepper motor;

Fourth, the replacement of AC servo motor can almost completely overcome the vibration and noise, but the cost is higher;

Fifth, add magnetic damper on the motor shaft, this product has been on the market, but the mechanical structure has changed greatly.

Generally, the stepper motor shake is caused by the situation that the stepper motor is running at low speed, and the solution to this situation is usually as follows

If the stepper motor happens to be working in the resonance zone, the resonance zone can be avoided by changing the mechanical transmission such as the reduction ratio;

Stepper motor drivers with subdivision are the easiest way to do this;

It can be replaced with a stepper motor with a smaller step moment angle, and if you are using a two-phase stepper motor, it can be replaced with a three-phase or five-phase stepper motor;

Replace it with an AC servo motor, which can avoid jitter, but the cost is very high;

Magnetic dampers can be added on the shaft of the stepper motor, but the disadvantage is that the structure of the mechanical structure is changed;

The motor shake is suppressed by a control algorithm that prevents motor jitter.

You haven't finished the program yet. o(╯□o。。。The motor swing is likely because the lines of your various phases are not connected, or the pulse sequence you give is not right...

The possible reasons why the stepper motor always swings back and forth at an angle are: the driving frequency subdivision is set incorrectly; The drive acceleration is set incorrectly; The load is too large.

A stepper motor driver is an actuator that converts electrical impulses into angular displacements. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle (called the "step angle") in a set direction, and its rotation is to run step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation and positioning.

Driven by segmentation! Subdivision drive is an effective method to specifically solve the low-frequency vibration of stepper motors.

If there is a tooth belt, the belt is tightened first, the deceleration time is extended, the acceleration process is increased, and the steering stops for more than 50ms.

You can add a shock ring to try it out, it should help you.

The stepper motor is open-loop control, which means "the signal is sent out regardless of it", and the servo motor is closed-loop control (the signal is sent out and controlled and managed through feedback). The significant disadvantage of the stepper motor is that the stepper motor is prone to low-frequency vibration at low speed, which is very unfavorable to the normal operation of the machine.

The frequency of vibration is related to the load situation and the performance of the drive. This low-frequency vibration phenomenon determined by the working principle of the stepper motor should generally use damping technology to overcome the low-frequency vibration phenomenon, such as adding a damper to the motor, or using subdivision technology on the driver.

Of course, this original shortcoming of stepper motors has been improved.

One is that there is a matching problem between your motor and the drive. In addition, the coarse is that the current is too large. In addition, the conversion frequency inside the driver is close to that of Soshen and can be heard by the human ear, so the frequency is increased.
