Stepper motors can be damaged or even burned due to overheating if they are blocked for a long period of time, so stepper motor blocking should be avoided as much as possible.
Stepper motor stalling can be caused by excessive mechanical resistance, insufficient drive voltage or insufficient drive current. In the design and use of stepper motors, should be based on the specific circumstances of a reasonable choice of motor models, drivers, controllers and other equipment, and reasonable setting of stepper motor operating parameters, such as drive voltage, current, speed, etc., in order to avoid motor stalling.
the following points should be noted when using stepper motors:
1、Appropriately reduce the load of the stepper motor to reduce the possibility of blocking.
2、Regularly maintain and service the stepper motor, such as cleaning the inside of the motor and lubricating the bearings, to ensure the normal operation of the motor.
3、Adopt protective measures, such as installing overcurrent protection devices, over-temperature protection devices, etc., to prevent the motor from being damaged due to overheating and other reasons.
In summary, the stepping motor may burn the motor in the case of a long time blocking, so the motor should be avoided as much as possible to avoid blocking, and at the same time to take appropriate protective measures to ensure the normal operation of the motor.
The solution of stepping motor blocking
The solutions for stepping motor blocking are as follows:
1、Check whether the motor is normally powered, check whether the power supply voltage is in line with the rated voltage of the motor, and whether the power supply is stable.
2、Check whether the driver is working normally, such as whether the driving voltage is correct and whether the driving current is appropriate.
3、Check whether the mechanical structure of the stepper motor is normal, such as whether the bearings are well lubricated, whether the parts are loose, etc.
4、Check whether the control system of the stepping motor is normal, such as whether the output signal of the controller is correct and whether the wiring is good.
If none of the above methods can solve the problem, you can consider replacing the motor or driver, or seek professional technical support.
Note: When dealing with stepper motor blocking problems, do not use excessive drive voltage or drive current to “force” the motor, which may lead to motor overheating, damage or burn, resulting in greater losses. Should be based on the actual situation step by step to investigate the problem, find out the root cause of the problem, and take appropriate measures to solve it.
Why does the stepper motor not turn after blocking the rotation？
The reason why the stepper motor does not rotate after blocking may be due to damage to the motor or the protection measures of the motor are triggered.
When a stepper motor is blocked, if the driver continues to output current, a large amount of heat may be generated inside the motor, causing it to overheat, be damaged, or burn out. In order to protect the motor from damage, many stepper motor drivers are equipped with a current protection function that automatically disconnects the power output when the current inside the motor is too high, thus preventing the motor from overheating and damage. In this case, the stepper motor will not rotate.
In addition, if the bearings inside the stepper motor show resistance due to excessive wear or poor lubrication, the motor may be blocked. If the motor is run for a long period of time, the bearings inside the motor may be severely worn and may even become stuck or jammed. In this case, if the bearing has been damaged, the motor will not be able to rotate properly.
Therefore, when the stepper motor does not rotate after blocking, it is necessary to first check whether the motor is damaged, and if the motor is not damaged, it is also necessary to check whether the driver is working properly and whether the circuit is malfunctioning and other problems, so as to find out the root cause of the problem and solve it.
