How to overcome vibration and noise in low-speed operation of a hybrid stepping motor

There may be multiple reasons for vibration and noise in a two-phase hybrid stepper motor during low-speed operation, and the following are some common solutions:

Choose an appropriate driver: Choosing an appropriate driver can effectively reduce motor vibration and noise. It is recommended to use a microstep driver, as it can divide the stepper motor's step into smaller microsteps, making the motor run smoother.

Increase current: When the motor operates at low speed, the current decreases, which can lead to increased motor vibration and noise. Increasing the current to improve the motor's torque and stability can effectively reduce vibration and noise.

Reduce load: Excessive load can also cause increased motor vibration and noise. Reducing the load can lower motor vibration and noise.

Install shock absorbers: Installing shock absorbers between the motor and external structures can effectively reduce the transmission of vibration and noise.

Check motor bearings and mechanical structures: Damage or poor design of motor bearings and mechanical structures can also cause increased motor vibration and noise. Checking and replacing damaged bearings and structures or redesigning the mechanical structure can effectively reduce vibration and noise.

Use low-noise materials: Selecting low-noise materials in the manufacture of motors and mechanical structures can also effectively reduce vibration and noise. For example, using rubber or other materials can reduce the transmission of vibration and noise to external structures.

In summary, there are many ways to reduce motor vibration and noise. The appropriate solution should be selected based on the actual situation.
