How long do motor withstand in times of lock rotor current before it burns?

The duration a motor can withstand lock rotor current before it burns out varies based on the motor's design and cooling methods. Typically, this period ranges from a few seconds to a couple of minutes, depending on the motor's thermal capacity and the specific conditions. Overheating due to prolonged lock rotor conditions can lead to insulation failure and damage. To prevent this, most motors have protection measures such as overload relays.
