Bore and shaft tolerances
The bore and shaft tolerances directly impact the motor’s performance and longevity. If the bore or shaft tolerances are too loose, the motor’s mounting may become unstable, causing vibration and eventual failure. If the bore or shaft tolerances are too tight, interference fits can occur, leading to excessive heat and wear. Manufacturers typically specify the acceptable bore and shaft tolerances for their servomotors, and it’s important to follow these guidelines during installation and maintenance. Regularly checking these parameters can ensure that the servomotor maintains optimal performance and reliability.
