Question

Stepper motor frequently forward and reverse, how long is the life? There is a project, consider using stepper motor forward and reverse to achieve, the process is forward transmission for 2 seconds, reverse for 2 seconds, no pause in between, used to achieve positioning, 24 hours of work. Don't know how long such a process motor or drive will last? Domestic brands. Is there a reliable brand, or how long is the service life if you use servos?

Answer 1

There is no definite value for the life of a stepper motor with frequent forward and reverse rotation, because it is affected by many factors. The following are some of the main factors that affect the life of a stepper motor:

1. Load conditions: The load conditions of a stepper motor have a great impact on its life. 

If the load is too large, the stepper motor will overheat, which will accelerate the wear and aging of the motor. 

Therefore, when using a stepper motor, it is necessary to select a suitable motor and driver according to the actual load conditions to ensure its normal operation and life.

2. Use environment: The use environment of the stepper motor also affects its life. If the use environment temperature is too high or too low, and the humidity is too high or too low, it will have a negative impact on the life of the stepper motor. Therefore, when using a stepper motor, it is necessary to select appropriate environmental conditions to ensure its normal operation and life.

3. Working mode: The working mode of the stepper motor will also affect its life. Frequent forward and reverse operations may increase the wear of the motor, but the specific degree of impact needs to be evaluated based on the design, quality and use conditions of the motor.

4. Maintenance: Regular maintenance of the stepper motor, such as cleaning, lubrication, and checking the connectors, can effectively extend the life of the motor.

5. Motor type and quality: Different types of stepper motors may have different designs and qualities, so their lifespans may also vary. At the same time, the quality and lifespan of the same type of motor may also vary due to different manufacturers.

In summary, the lifespan of a stepper motor with frequent forward and reverse rotation is a complex issue that requires consideration of multiple factors. Generally speaking, if the stepper motor works under appropriate load and environmental conditions and is well maintained, its lifespan can reach tens of thousands of hours or even longer. However, the specific lifespan needs to be evaluated based on actual conditions.

In order to extend the lifespan of the stepper motor, it is recommended to pay attention to the following points when using it:

* Select the appropriate motor and driver according to the actual load conditions.

* Select the appropriate environmental conditions for use.

* Regularly maintain the motor.

* Avoid frequent forward and reverse operations, especially under high load or high-speed operation.

* Pay attention to the heat dissipation of the motor to avoid overheating.

Answer 2

The life of a stepper motor depends mainly on its bearing wear and coil aging, and frequent forward and reverse use may accelerate these life reductions.

Generally, stepper motors need to replace bearings and grease after 200 hours of continuous operation, and need maintenance and maintenance after 500 hours of continuous operation.

Under normal use conditions, the life of the stepper motor can reach thousands of hours or even tens of thousands of hours, but the specific life should be determined according to the quality of the motor itself, the use environment, maintenance and other factors.

Therefore, in order to extend the life of the stepper motor, it is recommended to carry out regular maintenance and maintenance to avoid frequent forward and reverse use, and at the same time pay attention to the load and speed of the motor and other parameters during use.
