Can a 50HZ asynchronous motor be used at 60HZ frequency by using frequency conversion?

If the motor is operated at 60HZ using an inverter, can it be used this way? What impact will it have on the motor? Can it be used like this for a long time? Currently, the current under load during on-site monitoring is 18A, with a maximum of around 27A, and it is used for mixing. Please help analyze this: handshake
In that case, there should be no problems, but one issue might arise: if the motor rotates too fast, it will experience high-speed demagnetization, resulting in a significant decrease in its torque.
No problem, it has been in use for 15 years already! However, the impact of inverters on motors relates, on one hand, to the bearings, as the frequency of lubrication may need to increase ； Secondly, the harmonics generated by the inverter have a certain impact on the motor windings, so it is advisable to check them regularly!
Thank you very much, -------------:victory::handshake
