When a motor shaft breaks, it means that the motor shaft or the parts connected to the shaft break during operation. Motors are vital drives in many industries and equipment, and a broken shaft can cause the equipment to stop running, causing production interruptions and losses. The following article explains the causes of motor shaft breakage.
01 Overload
When the motor is subjected to work exceeding its rated load, the shaft may break. Overloading may be caused by a sudden increase in load, equipment failure, or improper operation. When a motor cannot handle excessive loads, its internal materials may not be able to withstand the pressure and break.
02 Unbalanced load
If an unbalanced load is installed on the rotating shaft of the motor, the vibration and impact force during rotation will increase. These vibrations and impact forces can cause stress concentration at the rotating shaft, eventually leading to shaft breakage.
03 Shaft material problem
Quality problems with the material of the motor shaft may also lead to shaft breakage. If the material of the rotating shaft does not meet the requirements, such as defects, insufficient material strength or expired service life, it will be prone to breakage during work.
04 Bearing failure
The bearings of the motor are important components that support the operation of the rotating shaft. When the bearing is damaged or excessively worn, it will cause abnormal friction in the rotating shaft during operation, increasing the risk of shaft breakage.
05 Design or manufacturing defects
When there are problems in the design and manufacturing process of the motor, shaft breakage may also occur. For example, if the factor of load change is ignored during the design process, there are material quality problems or improper assembly during the manufacturing process, etc., it may cause the motor’s rotating shaft structure to be unstable and prone to breakage.
06 Adjustments and corrections
Regularly check and adjust the alignment and balance of the motor to ensure proper operation and stability.
07 Training operators
Provide correct operating instructions and training to operators to ensure they understand correct operating methods and maintenance requirements.
To sum up, motor shaft breakage may be caused by various reasons such as overload, unbalanced load, shaft material problems, bearing failure, design or manufacturing defects, vibration and shock, temperature problems, and improper maintenance. Through measures such as reasonable selection of motors, balanced loads, use of high-quality materials, regular maintenance and training of operators, the risk of motor shaft breakage can be reduced and the normal operation of the motor and the continued stability of the equipment can be ensured.
